    摘要: PROBLEM TO BE SOLVED: To provide a shotcrete admixture having excellent powder flowability, in which quantification is possible through the use of a transporting pump although the admixture includes a liquid chemical.
    SOLUTION: The shotcrete admixture includes an oil absorbing powder carrying a liquid chemical (a defoamer or a water reducing agent) and also is a dust reducing agent for shotcrete including an oil absorbing powder, which carries a liquid chemical, and a water-soluble cellulose compound. As for the oil aborbing powder, non-crystalline silicon dioxide, sepiolite, diatomaceous earth and the like having an oil absorption amount of at least 30 mL/100 g can be used.

    摘要: PROBLEM TO BE SOLVED: To provide a method for avoiding internal shrinkage or self-shrinkage of a cement or concrete structure.SOLUTION: A fibrillated carboxyalkyl cellulose, cellulose alkylsulfonic acid, phosphorylated cellulose or sulfated cellulose having a degree of substitution of 0.01-0.45 is added to a cementitious material. The fibrillated carboxyalkyl cellulose, cellulose alkylsulfonic acid, phosphorylated cellulose or sulfated cellulose has a substituent content of 10-150 mEq/100 g cellulose fiber. The fibrillated carboxyalkyl cellulose, cellulose alkylsulfonic acid, phosphorylated cellulose or sulfated cellulose is 0.1-5 mass% of the dry weight of the cementitious material.
