A Study on the Engineering Properties of Micro Fine Hybrid Silicate Based Grout
초록
In 1925, H.J. Joosten was the first in the world to use chemical injection grouts composed of sodium silicate and calcium chloride. This unique development prompted the introduction of other chemical grouting techniques. Among these chemical grouting techniques, sodium silicate based grout has been the most widely used in the world, but it has not been generally considered to be a permanent material. Therefore, studies to improve the weak points of sodium silicate based grout have been conducted, and new applications of grout were recently developed. We also developed the micro fine hybrid silicate grout of suspention type which properties are sepecialized as the high strength and durability, according to the reactant of special sodium silicate grout and the high strength hardener. As the results of this study we could derive the 2 times over high strength of Micro fine hybrid Silicate grouting method(MS method) more than that of the ordinary sodium silicate grout. And also we could confirm that the alkali leakage of micro fine hybrid silicate grout is less than that of ordinary sodium silicate grout. So we could get the high strength and durability of hybrid silicate grout are superior to those of ordinary sodium silicate grout.
