A study of the use of powdered limestone rocks from the sub process from CHUM phae glory stone mill. Tambon Phu district, Khon Kaen province, Wang sawap replace the cement in concrete production, mass, liquid foam and powder mixed light aluminium. Using the ratio: limestone powder: cement is equal to 0.0, 1.0, 0.95:0.05:0.10:0.90, 0.85, and 0.20 0.15:: 0.80 percent by weight, quantity or bio-foam 2 of all ingredients, and quantities of powdered aluminium, 1 per cent of all ingredients. Water mixing ratio (W/C) binding is equal to the mass of concrete forming 0.6 7.5 cm x 20 cm size light x 30 cm test compression is being received. The water absorption values, the density values. The strength and shrinkage at the age of 7, 14 and 28 days curing. Results of the study showed that when limestone powder and more. Up getting pressure and the density value is reduced. Best value water absorption increases, and found that the best ratio is the ratio of limestone powder is used instead of cement, 2 sets of equal to 0.05:0.95 by weight values are compressed 38.81 kg square centimeters up 28.29% water absorption value of density is equal to k, pls 1007.40.Mato cubic meters. The strength is equal to 0.50 mega Paschal II and the shrinkage does not exceed 1 cm at age 28 days to mature, water absorption through the benchmark of TIS 2601-2556 (2013), although the strengths and value of the density decreased, but remained in the standard criteria. TIS 2601-2556 (2013) Mass concrete block filled light bubbles
