## ABSTRCT Changes in physical and chemical properties in the mortars with different replacements by fly ash and silica fume when immersed in 2 % H2SO4, 10 % Na2SO4 and 10% MgSO4 solutions for 3 years were investigated. The long-term exposure test data showed that the replacement of portland ceme
Large amounts of fly ash (FA) and limestone powder (LP) wastes are accumulating in countries all over the world. Most of these wastes are abandoned and cause certain serious environmental problems and health hazards. In this study, LP waste and class-C FA were used to produce a composite material wi
Low calcium fly ash is a good pozzolan to improve sulfate resistance of OPC cement. Benefical effects produced by this pozzolan on OPC are studied in the present paper. Results of sulfate resistance evaluated by Koch & Steinegger method are presented for four OPC + fly ash cements. The changes in mi
Raw bagasse ash collected from the Thai sugar industry has a high loss on ignition (LOI) of $20%. When ground and ignited at 550 Β°C for 45 min, the LOI was reduced to $5%. These high and low LOI of ground bagasse ashes were blended in the ratios of 1:2 and 2:1 by weight to give ground bagasse ashes
