The Uses and Importance of Aggregates in Construction Aggregates have the important role in giving the necessary strength for concrete. Concrete transitions are the interfacial region between the aggregate and cement paste and this is the one that is responsible in giving compressive strength to the cement. The aggregate should be equiangular and round in size and this must not be irregular and flaky. But, the use of angular aggregates is highly advised because these kind of aggregates comes with good interlocking effects, having minimum surface area and will less mortar in covering the surface. During the extraction time of the aggregates, care must be taken to make the aggregate go sieve analysis or washing before this will be used. Because any presence of harmful materials that involves clay, silt or acidic salts could affect the strength and the durability of concrete, which will lead to inhomogeneity in composition and in the failure of the structure if this will be subjected to eccentric loading. There are some associations that specifies four grading zones for fine aggregates that are placed in order for decreasing particle size that starts from coarse sand and ending with fine sand. It is best that you don’t use fine sand in making RCC structures because they are porous and could cause corrosions in the reinforcement.

Fine aggregates have to include natural sand and crushed natural stone and gravel and these must be able to pass through a sieve of opening for about 4.75 mm where the ones that are retained completely are coarse aggregates that would include uncrushed gravel and stone and big boulders.
Why People Think Materials Are A Good Idea
Aggregates have to be inert chemically in nature and needs to be tough sufficiently, hard and needs to have good bearing capacities. Aggregates that are well-graded and used in a cement mixture helps to reduce the presence of air voids and also helps in providing sufficient strength and durability to the concrete. There are actually some tests that are being carried out to some aggregates such as abrasion, impact tests and soundness tests of aggregates which are done by dissolving them to a particular solution of sodium and magnesium sulphate. To provide the necessary support for concrete dams which has a huge mass, aggregates which were formed by igneous rocks are the ones that are preferred highly. Even though aggregates are known commonly as inert fillers in concrete, the different properties of aggregates have a large impact to durability, strength, workability and on the economy of concrete. The different properties of aggregates will allow designers and contractors with the most flexible option to meet their design and construction requirements.
