THE EFFECT OF SODIUM SULFONATE ADDITION ON NON-AUTOCLAVED AERATED CONCRETE

Abstract

This study investigates the features of producing non-autoclaved aerated concrete with the addition of sodium sulfonate, used to stabilize foam formation in the mixture. The chemical mechanisms of gas generation and the effect of the surfactant additive on the formation of the material’s structure are examined. Optimal dosages are determined depending on the designed density of the products. Experimental results show that the use of sodium sulfonate contributes to increased strength and reduced density of aerated concrete while eliminating the need for autoclave treatment.
