Utilization of industrial wastes and unprocessed micro-fillers for making cost effective mortars

摘要

The use of fly ash, slag, silica fume and marble dust as replacement of cement on the compressive strength and cost effectiveness of low w/c ratio superplasticized portland cement mortars was investigated. The blending of industrial wastes in mortars was also studied. Cement mortars (1:3 and 1:6) incorporating various proportions of industrial wastes were designed to have a flow of 110 +- 5 percent. The compressive strength of mortars with and without superplasticizer was determined at 1, 3, 7, 28 and 180 days and their cost effectiveness was analyzed.
