suitability of allinaggregates as a substitute for separate gneiss and sand used for concrete production in order to reduce the cost of concrete production for low cost housing without compromising on quality and strength. Materials and Methods Materials The allin aggregates .
Higher the surface area, greater is the water demand to coat the particles and generate workability. Smaller maximum size of coarse aggregate will require greater fine aggregate content to coat particles and maintain cohesiveness of concrete mix. Hence 40 mm down coarse aggregate will require much less water than 20 mm down aggregate.
