Jul 04, 2020 These particles fit together to produce a dense material approx 70% of the volume of the concrete is aggregate. So in concrete, these pieces of aggregate are bound together by a mixture of cement and water to produce a material that is initially moldable and with time developed strength and becomes stiff.
