PURPOSE:To provide a cement mortar compsn. having not only fire protection performance more effective than flame retardancy but elongating performance with which the mortar can enough follow behaviors of the base body such as cracking. CONSTITUTION:This elastic cement mortar compsn. for fire protection coating is obtd. by kneading (1) 100 pts.wt. of portland cement and/or white cement, (2) 10-40 pts.wt. of elastic-type polymer dispersion calculated as solid content having <=-20 deg.C glass transition point (Tg), (3) 50-200 pts.wt. of at least one kind of hydrated metal compd. prepared to have 50-150mum grain size, and a proper amt. of water. |
