Background

Aggregate is also known as "aggregate". The concrete and mortar are granular materials with the functions of framework and filling. There are two kinds of fine aggregate and coarse aggregate. The diameter of the fine aggregate particles is between 0.16 and 5mm, natural sand such as river sand, sea sand, valley sand and the like is generally adopted, and when the natural sand is lacked, artificial sand ground by hard rocks can be used; the particle diameter of the coarse aggregate is more than 5mm, the common crushed stone and pebbles exist, under the same condition, the strength of the crushed stone concrete is higher than that of the pebble concrete, but the crushed stone is formed by crushing rocks, and the cost is higher than that of the pebbles.
