Toughened glass panels used as a glazing material in multistorey buildings are known to fracture prematurely when they contain nickel sulfide inclusions as a result of the – phase recrystallisation in nickel sulfide. The kinetics of this recrystallisation were studied by differential scanning calorimetry (DSC) under isothermal and non-isothermal conditions. The recrystallisation was observed to be a two-step process with an induction period followed by the phase change. A two-stage kinetic model was used to estimate the recrystallisation time under ambient conditions. These values were found to correlate well with the observed time to failure for glass panels installed in multistorey buildings.

Common approaches in practice to predict underground explosion-induced stress wave intensity are based on some empirical formulae. Those empirical formulae were obtained by different researchers based on their testing data at various sites. They can predict the peak particle velocities (PPV) and / or peak particle accelerations (PPA) of propagating stress wave at various locations. They usually include the effect of explosion loading density in terms of a decoupling factor, but do not take into consideration the effects of other explosion conditions, such as the charge chamber geometry, explosive location and distribution. In this paper, a previously calibrated numerical model is used to perform parametric calculations to investigate the effects of underground explosion conditions on stress wave propagation and damage at a granite site. Based on the numerical results, some formulae, which include the effects of various explosion conditions, are derived to predict peak particle acceleration (PPA), peak particle velocity (PPV) and principal frequency of stress wave in the granite mass. The proposed formulae are also compared with the empirical formulae obtained from blasting tests conducted at the site under consideration.

The degradation of poly(vinyl alcohol) was investigated using TG analysis and Fourier transform infrared spectroscopy to determine the effect of atmosphere on the process of degradation. In the spectra, four vibrational modes were identified that characterised the major steps of the degradation process. These were the O-H, C-H, C=O and C=C stretching modes. The mechanism observed for degradation in an inert atmosphere was in accordance with the accepted mechanism of elimination followed by pyrolisation. Evidence of conjugated polyenes, however, was not observed. For the air atmosphere, oxidation in both steps of the degradation process was observed.

View description>>

The long-term performance of concrete slabs in alumina refineries has been found to be mostly unsatisfactory. The effect of exposure of concrete to sodium hydroxide (NaOH) of various concentrations has been reported. Failure of slabs accidentally exposed to hot caustic has been observed to be associated with cracking, crystallisation of salts in the crack and seepage of caustic into subgrade, resulting in its expansion and uplift of the slabs. This deterioration mechanisms of concrete in caustic are, however, not well understood. This paper presents findings into the interaction between a range of supplementary cementitious materials (SCM), such as blast furnace slag and silica fume, and NaOH solutions. The influence of the type of cementitious material, water-to-cementitious material ratio, concentration and temperature of NaOH on their interaction was investigated by examining the change in length of unrestrained mortar and concrete prisms exposed to NaOH solutions. The likely effect of the deterioration mechanism on the performance of restrained structural components, such as industrial slabs, is also examined by monitoring model slabs exposed to NaOH. The choice of cementitious material and its implications on the caustic resistance of concrete slabs subject to NaOH attack are presented.

An overview of the development of stress laminated cellular timber bridge decks for short to medium span applications in Australia was presented. The testing program for both plate and cellular deck systems was based on 'full scale' laboratory testing, involving application of loads that modeled both the design serviceability and design ultimate conditions. The field performance of four prototype bridges utilizing the cellular deck system demonstrated the structural efficiency and cost effectiveness of the technology.

View description>>

Superior durability of fly ash concretes have been very well established by many research works throughout the world. However, the decision to use the fly ash concrete or not and also the fly ash content in the concrete is based on the cost of the concrete in most of the cases, if not all. Thus a methodology has been developed to estimate the optimum fly ash content for the lowest cost and maximum durability of the concrete. Concrete of different fly ash content were prepared and their costs were calculated. Durability properties of some of the concrete were determined by experimental measurement of their relative service life. The type of environment was also considered. Optimum fly ash content was determined based on cost, durability of the concrete, and the type of environment. The price structure of concretemaking materials in Australia was used as an example in the calculation of optimum fly ash content for the lowest price. It is expected that the price structure found in other countries would be different and accordingly the optimum fly ash content will be also different. However the methodology has been presented and this methodology can be used to calculate the optimum fly ash content for any price structure. This methodology provides scientific way of estimating the fly ash content which would give the lowest cost for an environment.

The potential use of Malaysian fly ash cement in concrete has been studied in terms of its influence on elastic properties, volume stability and durability properties. In durability studies, the resistance to chloride ingress, sulfate attack, and suppression of alkali-aggregate reactivity were examined. The results are presented and discussed. The role of the fly ash on heat of hydration, production of roller-compacted concrete, and high-strength, highperformance concrete have been proven in practice. Understanding the influence of fly ash on both fresh and hardened properties of concrete has led to its appropriate use in many important structures in Malaysia. They include the Petronas Twin Towers, the second Malaysia Singapore Causeway, and more recently considered for the construction of a major RCC dam. Properties of fly ash concrete are discussed with examples of application.
