This paper reports on the possible use of sewage sludge ash as a pozzolanic supplementary cementitious material to Portland cement. Samples of sewage sludge were incinerated at 700°C, 800°C and 900°C and these were then cooled in the furnace (FISS

This paper presents a model for the drying shrinkage of South African concretes, developed from laboratory data generated over the last 30 years. The model, referred to as the WITS model, is aimed at identifying the material variables that are the mo

Temperature gradients due to heat of hydration of cement can cause cracking and present serious structural and serviceability concerns in concrete structures. Engineers use a wide range of strategies to limit the potential for such cracking, mainly b

This paper reports on a study that was aimed at developing a coherent empirical relationship for the time to cracking of the cover concrete in a reinforced concrete structure, subjected to reinforcing steel corrosion that is induced by carbonation in

The hydration of cement is an exothermic reaction which generates around 300 kJ/kg of cement hydrated. In mass concrete structures such as dams and large foundations, this heat of hydration causes a significant rise in temperature in the internal sec

This paper presents results of a study into the effects of truck tyre crumb rubber particle size, as fine aggregate, on the compressive strength, shrinkage and creep behaviour of structural rubberised concrete. The study is motivated by a growing int

The current global waste tyre generation far exceeds its consumption in terms of recycling and re-use. The traditional recycling and re-use methods like thermal incineration have proven ineffective, costly and in some cases environmentally unsustaina
