Effect of Acrylate-Cement Grout on the Unconfined Compressive Strength of Silty Sand
Chemical grouting has been extensively used to improve the stability and durability of built structures by enhancing the engineering propertiesofsoils. The objective of this study was to investigate the effect of an newly developed acrylate-cementgrout, composed of component A (acrylicpolymer, catalyst, and hardener) and total weight, on the unconfined compressive strength of silty sand. component B (cement) having mixing ratios varying from 0.5% to 2% of The Three series of laboratory tests (geltime, expansion ratio, and unconfined compression strength) were carried out on reconstituted soil samples with avoid replacement ratio of 80% and 100% by acrylate-cement grout. The results showed that the optimum cement ratio of the chemical grout was 1.5% based on the unconfined compressive strength and the elastic modulus for the silty sand with grouting.
