Civil At Work: To Determine The Aggregate Crushing Value
· Theory: Aggregate crushing value is measured which relatively gives idea of his resistance to crushing under the compressive load applied gradually. Lower the crushing value stronger the aggregate again crushing. Therefore good quality concrete, aggregate having comparatively lower crushing value is to be preparable.
