PURPOSE:To provide a perlite mortar composition for plastering capable of preventing the mixing vol. loss of kneading material from being caused due to the breakage of perlite grain at the time of kneading. CONSTITUTION:This perlite mortar composition for plastering contains perlite. The composition contains 3-50vol.% (in internal ratio to the perlite) pieces of an elastic material, and the volume ratio of cement to the aggregate (the perlite and elastic material) is controlled to 1:1 to 1:5. Consequently, the mixing vol. loss ratio of the mortar is drastically reduced as composed with the conventional perlite mortar. |
