## properties of concrete using pebbles as coarse aggregate

the coarse aggregate is the volume of finished concrete, and the sand fills in the spaces between the larger stones of the coarse aggregate. the cement in its wet form should coat the individual pieces of aggregate and as the cement dries and hardens, it locks the gravel and sand into a matrix of small to larger aggregate pieces, giving strength to the concrete.get price

One property is the modulus of elasticity of the coarse aggregate. A higher aggregate modulus will result in a concrete having a higher modulus. As expected, a lightweight aggregate will have a lower modulus than the mortar paste. Conversely, a strong aggregate produces a concrete that is stronger than the mortar paste (Zhou 180).
