Summary:PURPOSE:To obtain lightweight aggregate for plastering which is excellent in coating workability of primer morter of a tile by constituting it of a CaCO3 foaming agent and a mineral lightweight aggregate having prescribed volume ratio in which degree of water absorption, bulk specific gravity and maximum particle diameter are specified respectively. CONSTITUTION:The above lightweight aggregate for plaster is constituted of both a CaCO3 foaming agent contg. alumina powder as the forming agent and 100-500pts.wt. mineral lightweight aggregate having <=30% degree of water absorption, <=0.5 bulk specific gravity and <=2.5mm maximum particle diameter for 100pts.vol. CaCO3 forming agent. As the mineral lightweight aggregate, the mineral foaming lightweight aggregate such as both material obtained by mixing asphalt with cement paste and perlite coated with organic or mineral material having waterproofness is utilized. Since the above-mentioned lightweight aggregate is light in weight fatigue is not accompanied with coating operation of primer morter of a tile and workability is made excellent and a defect such as floating and cracking is hardly caused because sagging is not formed.
