PURPOSE:To obtain a cellular mortar composition effectively useful for spraying, troweling operations; etc. CONSTITUTION:The characteristics of this cellular mortar composition is as follows: (1) a lightweight aggregate having <=0.2kg/l bulk specific gravity is mixed in a cellular mortar; (2) the lightweight aggregate having <=0.2kg/l bulk specific gravity is an expanded plastics capable of absorbing the shock in spraying and (3) the lightweight cellular aggregate having <=0.2kg/l bulk specific gravity is pulverized and expanded polystyrene. Thereby, the cellular mortar composition, having a small flow value, providing a large thickness by spraying the composition at a time, hardly causing a loss of jumping back and misting in spraying without breaking cells by the shock in the spraying and effectively useful for spraying, troweling operations, etc., can be provided. |
