Study of the effect of composite deflocculant on changes in physical and mechanical properties of heat-resistant concrete during heat treatment
Santrauka
Results are presented for an X-radiographic study of a cement matrix with addition of a composition of two deflocculants – sodium tripolyphosphate and polycarboxylate ester after hardening and heat treatment at 60 – 110°C. The effect of composite deflocculant on changes in concrete physicomechanical properties and heat resistance after firing at 1000 and 1200°C is evaluated.
