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 before the age of 7, 14 and 28 days to mature, respectively. Test compression is being received. Water absorption value up density up to stretch shrinking standards. 2601-2556 (2013) Hasyim. strength and are in accordance with มยผ. 1211-50.
