SHRINKAGE REDUCING AGENT FOR CEMENT AND HYDRATION HEAT REDUCING AGENT FOR CEMENT

摘要

PURPOSE: To provide a shrinkage reducing agent for cement and a heat-of- hydration reducing agent for cement excellent in handling property and addition effect. ;CONSTITUTION: The shrinkage reducing agent for cement and the heat-of- hydration reducing agent are made of neopentylglycol. Since neopentylglycol is solid at ordinary temp, it cam be powdered and mixed with cement or the like for use. And since neopentylglycol previously is soluble in water it can be used in aquous solution state, thus improving handling property. Extremely excellent shrinkage reducing effect and heat-of-hydration reducing effect are attained only by adding relatively small quantity of neopentylglycol.;COPYRIGHT: (C)1994,JPO&Japio
