Experimental Study on Influential Factors of Adiabatic Temperature Rise for Mass Concrete
Experiments on adiabatic temperature rise are systematically carried out in this paper, the characteristics of adiabatic temperature rise of concrete with different mineral admixtures are compared. The influence of binder amount, water-binder ratio, placing temperature and superplasticizer is also studied. The results reflect that binder is the main factor affecting adiabatic temperature rise, mineral admixtures such as fly ash can significantly reduce the rate and amount of heat development, large quantity substitution of slag in concrete can relieve the concentrative heat liberation, the retarded superplasticizer can prolong the exothermic process effectively and high placing temperature has adverse effect on temperature control of mass concrete.
