    摘要: A method of curing cementitious material comprising added a fibrillated carboxyalkyl cellulose, cellulose alkylsulfonic acid, phosphorylated cellulose or sulfated cellulose having a degree of substitution of 0.01 to 0.45 to the material during mixing. The fibrillated carboxyalkyl cellulose, cellulose alkylsulfonic acid, phosphorylated cellulose or sulfated cellulose may also include bleached or partially bleached wood pulp fiber. The fibrillated carboxyalkyl cellulose, cellulose alkylsulfonic acid, phosphorylated cellulose or sulfated cellulose has a substituent content of from 10 to 150 meq/100 g cellulose fiber. The fibrillated carboxyalkyl cellulose, cellulose alkylsulfonic acid, phosphorylated cellulose or sulfated cellulose is 0.1 to 5% by weight of the dry weight of the cementitious material. The structure produced by the method. The autogenous shrinkage of the cementitious material is reduced.
