Practical method for mix design of cement-based grout

Abstract

Cement-based grout is made of mixed water and cement, which is sometimes also added with sand and admixtures. It is commonly used for soil improvement, for repairing the damages on concrete and masonry, or for the construction of preplacedaggregate concrete. Currently there are hardly any available practical methods which can be used to carry out the grout mix design. The practical method to carry out cement-based grout mix designs suggested in this paper is based on some graphics and or empirical equations, which are derived from regression analyses of laboratory test results data to simplify the mix design process.
