Abstract:
The paper presents the results of a laboratory investigation into the effects of subjecting concretes (made from OPC and blends of OPC and slag) to adiabatic temperature cycles. The adiabatic cycle is similar to that which concrete at the centre of a large mass would undergo during the first few days after placing. Concretes with two different cement contents (300, 450 kg/m3) were made with slag replacement levels of 50% and 70% by mass of cementitious material. The properties investigated were: adiabatic temperature rise, compressive and tensile strength development and modulus of elasticity. Tests were carried out at ages between 1 day and 6 months.
