Abstract: It is studied that the properties of high -performance grouting admixture and grouting material prepared withgrouting admixture. The tests show that the grouting material prepared with cement(P-O 52-5R or P?O 42-5R), riversand, crushed stone and grouting admixture gives good technical properties, convenient construction and low cost. Withadding grouting admixture, grouting material can be preparedto meet the requirements of different projects, andthis groutingadmixture has been applied extensively in projects.
