COMPRESSIVE STRENGTH ESTIMATION METHOD FOR SOIL-CEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method capable of estimating compressive strength at a predetermined material age of soil-cement in accordance with a construction condition of a soil-cement development site.;SOLUTION: A construction condition that is defined by physical properties of soil particles included in soil-cement, a mix proportion of cement milk included in the soil-cement and components of the cement milk included in the soil-cement is set. A relationship between a cement-water ratio C/Wscu of the soil-cement in the construction condition and compressive strength qu28 of soil-cement at predetermined material age is calculated. Based on measured density γscu of the soil-cement, the cement-water ratio C/Wscu of the soil-cement is calculated. By substituting the calculated cement-water ratio C/Wscu(=Ya) into the relationship, the compressive strength qu28 (=Za) of the soil-cement at the predetermined material age is estimated.;COPYRIGHT: (C)2015,JPO&INPIT
