Internally curing cement based materials
A method of curing cementitious material comprising added a carboxylated bleached wood pulp fiber to the material during mixing. The fiber has a carboxyl content of from 10 to 70 meq/100 g cellulose fiber. The fibers are 0.1 to 5% by weight of the dry weight of the cementitious material. The structu...

| description | A method of curing cementitious material comprising added a carboxylated bleached wood pulp fiber to the material during mixing. The fiber has a carboxyl content of from 10 to 70 meq/100 g cellulose fiber. The fibers are 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. |
