Effect of Amount of Deflocculant on Change in Physicomechanical Properties of Medium-Cement Heat-Resistant Concretes During Drying and Heat Treatment

  • Published:
Refractories and Industrial Ceramics Aims and scope

Results are provided for a study of the properties of a cement matrix of medium-cement heat-resistant concrete with deflocculant additions, i.e., sodium tripolyphosphate and polycarboxylate ester. The effect of amount of deflocculant and heat treatment temperature on the change in matrix hydration product composition after hardening at 20°C and drying at 60, 80, and 110°C is considered. Comparative analysis is performed for the change in concrete physicomechanical properties and their heat resistance is evaluated in relation to amount and type of deflocculant.
