Product Description

Aggregates are granular materials, that aren’t organic, with a natural source such as sand, gravel, crushed stone or artificial source such as blast furnace slag, expanded perlite and expanded clay, which are gathered together by means of a binding agent consisting of cement-water mixture in concrete production.
Aggregate has a very important place in concrete production in economic and technical terms. As its cost is much lower than the cement, aggregate is considered as a filling material which is cheap and used in concrete. Using aggregate in concrete prevents or reduces volume change of the hardened concrete, increases concrete durability against environmental effects and helps providing strength required in concrete due to its high strength capacity. Aggregate can be analysed in two categories as coarse and fine aggregate. At construction sites, coarse aggregate is called as “chips or gravel” and fine aggregate is called as “sand”. The criterion used for sorting out these two components from each other is the size 4 mm. The part consisting of grains larger than 4 mm is called the coarse aggregate and the one smaller than 4 mm are called the fine aggregate...
Since 60-80% of concrete volume is composed of aggregate, it needs to be careful while making the choice. Aggregate should have the necessary strength and durable to external factors. The physical and mechanical properties of aggregate should be in nature that will meet the desired conditions. The aggregate of a concrete that will be exposed to wear should have sufficient wear resistance. And the aggregate of a concrete that will be used in frosty climates should meet the standards established for the frost effect in terms of resistance.
For aggregate component to display a proper granulometry is highly important. The air gap within an aggregate with a good granulometry will be less. Accordingly, its density will increase. In this way, the cement-water mortar within the total concrete volume can be used more economically and the concrete can be put into the desired place without impairing its quality.
