  • Concrete With Ceramic Waste Aggregate Sciencedirect

    use of hazardous industrial wastes in concrete-making will lead to greener environment. In ceramic industry about 30% production goes as waste, which is not recycled at present. In this study an attempt has been made to find the suitability of the ceramic industrial wastes as a possible substitute for conventional crushed stone coarse aggregate.the effect of aggregate properties on concrete concrete is a mixture of cementious material, aggregate, and water. aggregate is commonly considered inert filler, which accounts for to percent of the volume and to percent of the weight of concrete.
