 · We present here a more rational method for the mix design of concretes of plant aggregates that avoids as far as possible the pitfalls reported previously. It was tested on rice husks concretes. It should be remembered that the rice husk is the residue of rice husking, which makes it possible to process the harvested rice or "paddy rice" into whole rice or "cargo rice".

How Coarse Aggregate Affects Mix Design of Concrete?

Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture. It is reported […]

Aggregates

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.
