Скачать или смотреть Rockfill Concrete - Good tools and machinery make the work more efficient

Rockfill concrete (also known as "stone concrete" or "crushed stone concrete") is a construction method commonly used in large-scale infrastructure construction, civil engineering, and water conservancy projects. This method combines the advantages of stone and concrete by mixing crushed stone or large stones with concrete to form a strong and durable structural material.

Concept and application

Rockfill concrete is a method of casting crushed stone, pebbles or large stones in a certain proportion with cement, sand, stone, etc. This material has superior performance in some specific scenarios and is often used for:

Dam construction: such as in the base and main structure of the dam, it can increase the stability of the structure.

Road infrastructure: In some large-scale road construction, especially highways, bridge foundations, etc., rockfill concrete is often used to fill and reinforce the roadbed.

Bridge piers and foundations: especially those structures that need to withstand greater pressure and weight.

Mass concrete engineering: Because rockfill can reduce the amount of concrete used and reduce temperature stress, it is suitable for the construction of mass concrete.
