Aggregate Testing
07/11/2017 · Aggregate is divided into coarse aggregate and fine aggregate. One of the main constituent materials of concrete. Mainly acts as a skeleton and reduces the volume change due to the shrinkage of the cementitious material during the coagulation and hardeni ng process, and also serves as an inexpensive filler for the gelling material. There are natural aggregate and artificial aggregate of .

use of iron ore as coarse aggregate in concrete making
May 14, 2018· To achieve the required concrete density to absorb the radiation a combination of highdensity aggregates steel shot (fine aggregate) and hematite ironore (coarse aggregate) was used. The use of high density aggregates increased the cost for 40 Mpa concrete from approximately to R7 per cubic metre of concrete in 1996.
