To the laymen, aggregates could be inert filler within a concrete mix. However, only a technically sound individual can actually understand the importance of this component within a concrete mix. Aggregates actually play crucial role and influence the properties of both fresh and hardened concretes. Alterations in gradation, unit weight, maximum size and moisture content of this component can drastically change the character and performance of concrete mixes. On the other hand, using the maximum allowable size of aggregates proves economic. As such, the component reduces the requirement for cement, which is the most expensive item used in concrete mixes.
The component also provides volume stability to hardened concrete. Cement pastes have higher chances of shrinkage as compared to that of aggregates. It is important to control the shrinkage of the concrete material because it often leads to cracking. In order to avoid any mishaps, reputed construction firms subscribe to cement aggregate concrete testing these days.
