PROBLEM TO BE SOLVED: To provide a mortar capable of being flow extended and having high performance adiabaticity similar to organic adiabatic materials.SOLUTION: A mortar contains (A) a powder containing cement, an inorganic microballoon, a cement setting accelerator and a high performance water-reducing agent, (B) an additive agent containing a synthetic resin emulsion, water, an organic microballoon, a fine fiber, a thickner and a viscosity modifier, and the cement setting accelerator of 10 to 20 pts.wt. and a thickner of 0.3 to 0.6 pts.wt. based on 100 pts.wt. of cement is blended and a flow value when mortar is flow extended on a floor (measured according to JASS 15M-103) is secured at 160 to 250 mm so that light walking can be conducted on a cured body of the mortar about 24 hours after application (temperature at 20°C). The obtained cured body has a coefficient of thermal conductivity of 0.12 (W/m k) or less, a flexural strength of 0.5 (N/mm) or more, a compressive strength of 0.1 (N/mm) or more, adhesive strength of 0.4 (N/mm) or more and dry density of 0.3 (g/cm) or more. |
