Treatment of Medium- to Coarse-Grained Sands by Fine-Grained Portland Cement (FGPC) as an Alternative Grouting Material to Silicate-Ester Grouts

CODEN: CCAGDP

Abstract

Due to the inability of Ordinary Portland Cement (OPC) grouts to permeate such soil formations as fine- to medium-grained and/or medium- to coarse-grained sands and the problems associated with permanence and toxicity of chemical grouts, advanced studies have shown that fine grained portland cement (FGPC) based grouts may be used to overcome the difficulties mentioned above and hence, an opening in the market has appeared for the manufacture of very fine-grained cements. In this context, comparative laboratory studies were conducted on commercially available OPC, FGPC, and silicate-ester grouts, and it has been found that FGPC has better flow properties and bleed characteristics than OPC. Furthermore, its permeation into medium- to coarse-grained sand is as effective as silicate-ester grout and the strength of the sand gained by the injection of FGPC is higher than that of silicate-ester grouted sand.
