PURPOSE : Lightweight clay composition for forming constructional materials is provided to exhibit excellent compression strength, heat insulation and reduced weight, and to be employed in manufacturing block, brick, insulating material and/or constructional panels by admixing diatomaceous earth and loess, and adding a foaming solution and a soil solidifying agent to the mixture. CONSTITUTION : The clay composition comprises : 50wt. parts of diatomaceous earth and 50wt. parts of loess; 2-50wt. parts of foaming solution; and 2-10wt. parts of polymer aggregation solidifying agent containing polyacryl amide polymer aggregation agent and clay in a ratio by weight of 50 : 50 to 5 : 95 or clay solidifying agent. The clay solidifying agent includes : 5-20wt.%% of NH4Cl, 3-14wt.%% of NaCl, 1-6wt.%% of FeCl3, 7-20wt.%% of MgCl2, 3-20wt.%% of CaCl2, 1-10wt.%% of MgO, 1-10wt.%% of ethylene glycol, 1-6wt.%% of transparent water-proofing solution, and 10-30wt.%% of pure kaolin powder. © KIPO 2007
