<p>PROBLEM TO BE SOLVED: To obtain an inexpensive grout which has excellent flowability and which after curing has a moderate value of modulus of deformation, is free from bleeding, and has excellent deformation follow-up properties and a low drying shrinkage by incorporating a powdery mineral filler into a cement. SOLUTION: This grout comprises 100 pts.wt. cement and 40-310 pts.wt. powdery mineral filler (preferably having a fineness of 1,500-6,000cm<2> /g). It has a modulus of deformation after curing of 50,000kgf/cm<2> or lower. According to need, the grout may contain a water reducing agent, water, and other admixtures. It can be obtained, for example, by adding a powdery mineral filler and a water reducing agent to a cement in respective given amounts, premixing the mixture, adding water and optional admixtures thereto, and then kneading the resultant mixture. It has excellent performances, and is inexpensive due to the use of a cement as a binder.</p> |
