FIRE-RESISTANT MORTAR COMPOSITION
PROBLEM TO BE SOLVED: To provide a mortar composition capable of preventing explosive fracture in the fire-resistance test without damaging features that polymer cement mortar has, by eliminating problems of the conventional technology.SOLUTION: A fire-resistant mortar composition is characterized by containing 0.5 parts by mass or larger and 5 parts by mass or smaller of limestone fine powder, 1 part by mass or larger and 4 parts by mass or smaller of a polymer for cement admixture defined by JIS A6203, and 0.3 part by mass or larger and 1.5 parts by mass or smaller of organic short fibers having the melting point of 300°C or lower relative 100 parts by mass of cement, further a fire-resistant mortar composition characterized by containing 100 parts by mass or larger and 250 parts by mass or smaller of aggregate to 100 parts by mass of cement, and a fire-resistant mortar composition characterized in that a fiber length of the organic short fiber is 2 mm or longer and 15 mm or shorter.SELECTED DRAWING: None
