Utilization of Liquefying Additives in Clay Fly Ash Grouting Mixtures

Abstract:

Liquefying is an effort to achieve the lowest viscosity at the lowest water content in the mixture. Low water content tends to increase manipulation strength, and consequently to improve the physical and mechanical properties of the resulting mixture after hardening. The aim of this paper is to verify the influence of liquefying additives, namely, sodium hexametaphosphate and tripolyphosphate on properties of clay-fly ash grouting mixtures. Tested properties of these mixtures are viscosity, additional shrinkage, coefficient of filtration and compressive strength.
