Technological and Operational Properties of Cellular Concretes with Low Water-Hardening Ratio
Abstract: Investigation of the complex additive C-3m + NaOH on the process of gas formation and changes in the rheological properties of the cellular concrete mixture showed that a technologically acceptable rate of gas generation and a set of plastic strength is achieved at a consumption of 0,5 % of the superplasticizer C-3m by weight of the binder and 0,15 % of the additive NaOH. Introduction C-3m within 0,25…0,75 % continuously increased the fluidity of the mixture and allowed to reduce its water demand by 40 %.
Keywords: cellular concrete, gas formation, plastic strength, fluidity, sodium hydroxide, superplasticizer S-3m.
