<p>PURPOSE: An inner cured cement base material is provided to reduce the use amount of super plasticizer, and to enhance workability. CONSTITUTION: An inner cured cement base material comprises a cementum material. A cured cementum structure obtained from the cementum material additionally includes fibrillated nano or micro carboxyalkylcellulose, cellulose akylsulfonic acid, and cellulose which becomes phosphorylated or sulfated cellulose having degree of substitution(DS) of 0.01-0.45. The fibrillated nano or micro carboxyalkylcellulose, cellulose akylsulfonic acid, and cellulose which becomes phosphorylated or sulfated cellulose individually have of 10-150meq/100g of carboxyalkyl, akylsulfonic acid, phosphoric acid, or sulphuric acid content for the carboxyalkylcellulose, cellulose akylsulfonic acid, and cellulose which becomes phosphorylated or sulfated cellulose.</p> |
