A concrete sense of responsibility
Eco-conscious and exceptionally hard working, Dr Patrick Tang is looking to accommodate both structural and functional needs in his research and practical design work on building materials
At the very core of Dr Patrick Tang’s studies is the environment. He’s tying research on global energy demands to research on concrete technology and design, ambitiously and admirably seeking to find the least costly means of heating and cooling buildings.
“Energy efficiency has become a primary objective for policymakers at regional, national and international levels,” he concedes.
Nowadays, the construction industry is one of the dominant energy consumers in the world and this is only expected to increase as people continue to spend more time indoors and act on their preferences for thermal comfort.
“It is also concerning that Australia is currently failing to meet its emissions reduction targets.”
“Despite all of these facts, however, there is still not much in the way of practical research on energy efficient building materials, such as cementitious composites.”
“I’m determined to fill this gap.”
Patrick’s research career began in 1999, when he commenced a PhD at the City University of Hong Kong (CityU). Principally focused on construction materials engineering during his three-year probe, the industrious academic sought to develop a new class of structural grade lightweight concretes with fibre-reinforced composite materials.
“These are 1,435 to 2,100kg/m3 with corresponding strengths of 20 MPa minimum,” he describes.
“Perhaps most impressively, however, is the fact that they are capable of fulfilling both large-scale structural and functional requirements.”
Joining CityU’s prestigious Department of Civil and Architectural Engineering as a Senior Research Assistant and then Lecturer after receiving his award in 2002, Patrick looked to tackle another big assignment – this time on self-compacting concrete.
“This particular type has the ability to revolutionise building construction by increasing cost-effectiveness and drastically reducing noise nuisance,” he comments.
“Performance of its mixes were thoroughly analysed in laboratory and field tests.”
“From this, comprehensive design and application guidelines were developed for Hong Kong’s Housing Authority.”
Patrick relocated to the University of Newcastle in 2009, signing on to become a Lecturer and then Senior Lecturer in Construction Management within its School of Architecture and Built Environment. The talented mid-career researcher has since led a handful of successful endeavours, most recently entering into a long-term collaborative partnership with field experts from mainland China and Hong Kong.
“I also won an Australian Research Council Discovery Project Grant in late 2015,” he shares.
“This is for the creation of structural-functional integrated concrete (TESA).”
“As its name aptly suggests, it will be a structural material and a functional material.”
Undertaking a number of microstructure, mechanical, thermal and durability studies, Patrick is planning to investigate and optimise these properties specifically in TESA concrete.
“This subtype is made of porous structural lightweight aggregate, which is impregnated with liquid phase change materials and coated with epoxy resins and mineral admixtures,” he explains.
“The aim is to design it in a way that ensures consistent and adequate indoor temperature control.”
“We’ll be developing it over the next three years.”
Adding another category to his ever-expanding repertoire of concretes and cement, Patrick is hoping to research sustainable construction materials in the not-so-distant future.
“Photovoltaics, which involve the direct conversion of sunlight into electricity, have been receiving a lot of attention lately,” he elaborates.
“They’re really exciting because they serve multiple purposes, such as efficient energy conversion.”
“I’m looking forward to seeing where this project takes me.”

Â© 2016Phase change materials (PCMs) have great potential for applications in energy efficient buildings. In this study, an innovative method of macro-encapsulation of PCM using hollow steel balls (HSB) was developed and the thermal and mechanical performance of PCM-HSB concrete was examined. The macro-encapsulation system (PCM-HSB) was attached with a metal clamp (c) for better mechanical interlocking with the mortar matrix. The latent heat of PCM-HSB-c that can be acquired is approximately 153.1Â¿J/g, which can be considered to rank highly among PCM composites. According to the self-designed thermal performance evaluation, the PCMÂ¿HSB-c concrete panel is capable of reducing and deferring the peak indoor temperature. The indoor temperature of the room model using PCM-HSB-c panels was significantly lower than the ones with normal concrete panels by a range of 3Â¿6%. Furthermore, the test room using a higher PCM-HSB-c content demonstrated a greater ability to maintain a lower indoor room temperature for a longer period of time during heating cycles. In consideration of the mechanical properties, thermal performance and other aspects of cost factors, 50% and 75% PCM-HSB-c replacement levels are recommended in producing concrete.

Â© 2016 W. C. Tang et al.The utilisation of recycled concrete aggregate (RCA) in Self-Compacting Concrete (SCC) has the potential to reduce both the environmental impact and financial cost associated with this increasingly popular concrete type. However, to date limited research exists exploring the use of coarse RCA in SCC. The work presented in this paper seeks to build on the existing knowledge in this area by examining the workability, strength, and fracture properties of SCCs containing 0%, 25%, 50%, 75%, and 100% coarse RCA. The experimental programme indicated that at RCA utilisation levels of 25% to 50% little or no negative impact was observed for strength, workability, or fracture properties, with the exception of a slight reduction in Young's modulus.

Â© 2016 by the authors; licensee MDPI, Basel, Switzerland.Carbon nanotubes (CNTs) have excellent mechanical properties and can be used to reinforce cement-based materials. On the other hand, the reaction product of carbonation with hydroxides in hydrated cement paste can reduce the porosity of cement-based materials. In this study, a novel method to improve the strength of cement paste was developed through a synergy of carbon nanotubes decorated with carboxyl group and carbonation reactions. The experimental results showed that the carboxyl group (Â¿COOH) of decorated carbon nanotubes and the surfactant can control the morphology of the calcium carbonate crystal of carbonation products in hydrated cement paste. The spindle-like calcium carbonate crystals showed great morphological differences from those observed in the conventional carbonation of cement paste. The spindle-like calcium carbonate crystals can serve as fiber-like reinforcements to reinforce the cement paste. By the synergy of the carbon nanotubes and carbonation reactions, the compressive and flexural strengths of cement paste were significantly improved and increased by 14% and 55%, respectively, when compared to those of plain cement paste.

Â© 2015 Elsevier Ltd. All rights reserved.During the last decade, self-healing of concrete has attracted so much attention in the research community as a promising tool toward more durable and sustainable infrastructures. Although various self-healing approaches have been vastly studied, employment of different assessment methods in these studies has made it difficult to compare the efficiency of various self-healing mechanisms. This paper presents a review of test methods which have been commonly utilized to assess the efficiency of self-healing mechanisms in concrete. Three broad categories of assessment methods are considered, namely visualization and determination, assessment of regained resistance and assessment of regained mechanical properties. Moreover, as a pathway toward standardized evaluation of self-healing mechanisms, various assessment techniques are evaluated against four proposed essential criteria - reliability, quality of results, operational considerations and in-situ applicability.

Â© 2014 American Society of Civil Engineers.In this paper, three recycled coarse aggregates (RCAs) with different 24-h water absorptions (5.67, 3.12, and 1.98 wt%) were used to produce recycled coarse aggregate concretes (RCACs). Different water absorption rates were obtained by modifying the surface of RCAs with low and high concentration of alkaline organosilicone modifier that is stable in concrete. A normal aggregate concrete mixture was also prepared to serve as control mixture. The effect of RCA absorption on the microstructure (interfacial transition zone), mechanical properties (compressive strength, modulus of elasticity, and concrete-rebar bonding strength), and durability (shrinkage and water permeability) of the resulting RCAC was investigated. Test results showed that the surface modification of RCA was effective in reducing the water absorption. From micrographs, RCAC prepared with low concentration of surface modifier (No. 2 RCA) showed mechanical interlocking with the surrounding cement matrix. Among RCAC, No. 2 RCA (with low concentration of surface modifier) showed better mechanical and durability performance due to the mechanical interlocking which served as effective force transmission medium between aggregate/cement matrix. It can therefore be concluded that RCA prepared with low concentration of surface modifier improved the properties of RCAC. In addition, it may be used as a potential tool to reduce possible slump loss in fresh concrete thereby resulting in consistent mix and providing greater flexibility in mix design.

This paper presents the results of experimental investigation on macro encapsulated phase change material (PCM) incorporated in concrete walls of room models in real conditions. The focus of this study was to evaluate the effect of positions (externally bonded, laminated within and internally bonded) of macro encapsulated PCM in concrete walls on indoor temperatures and humidity levels of room models. Experimental results indicated that PCM models could adjust the indoor temperature and humility levels, however, its effectiveness was found to be greatly dependent on the position of PCM in concrete walls. The model with PCM laminated within the concrete walls showed the best temperature control and was effective in reducing the maximum temperature by up to 4 C. Whereas, the model with PCM placed on the inner side of concrete walls showed the best humidity control and reduced the relative humidity by 16% more than the control model. Therefore, it can be concluded that PCM models are thermally efficient and by reducing the relative humidity they provide comfortable and healthy indoor environment. Moreover, it is shown that the application of PCM in public housing flat of Hong Kong is economically visible with a recovery period of 11 years. Â© 2013 Elsevier B.V.

In this paper, a method of aggregate surface modification using cement paste with RLP (Redispersable Latex Powder) was proposed aiming to improve properties of recycled aggregates and the resulting concrete. In this study, the cement pastes with different dosages of RLP on RA surface modification were used and the effects on the mechanical properties of the resulting concretes were studied. The experiments were carried in accordance with specifications and test methods in Building pebble and gravel (GB/T 14685-2001) and Ordinary concrete mechanics performance test method standard (GB/T 50081-2002). The test results showed that the properties of recycled aggregates were not as good as those of natural aggregates, thus resulting in poorer mechanical properties of the recycled aggregate concrete. By means of aggregate surface modification, the values of water absorption of the recycled aggregate were reduced and consequently the mechanical properties (i.e. compressive strength and elastic modulus) of the resulting recycled concrete were increased. This research provides some useful practical insights to improving mechanical properties of recycled aggregate concrete. Â© (2013) Trans Tech Publications, Switzerland.

On 29th January 2010, a tragedy took place before the blissful Chinese Lunar New Year. An old tenement building in Ma Tau Wai collapsed in a sudden, causing 2 deaths and 4 injuries. Not only did this raise people's concerns to investigate the reasons the collapse of the tenement building, it also raised their awareness on old tenement buildings as well as protecting them from collapsing. In view of this, this paper investigates on condensation and how it might shorten the service life of that old tenement building. Â© (2014) Trans Tech Publications, Switzerland.
