Cement: As the main cementing material of concrete, it solidifies and hardens after mixing with water.
Aggregates: It includes fine aggregates (such as sand, fine sand, etc.) and coarse aggregates (such as crushed stone, crushed gravel, etc.), which play the role of skeleton in concrete and improve the compressive strength and durability of concrete.
Water: It plays the role of wetting and dispersing in concrete, so that materials such as cement, sand and gravel aggregates can be fully mixed, and transmit and promote the hydration reaction of cement during the hardening process.
In addition to the above main materials, concrete mixers can also add appropriate amounts of admixtures such as water reducers, retarders, antifreeze agents, etc. as needed to adjust the performance of concrete and meet specific engineering needs.
In short, concrete mixers are mainly used to prepare concrete, and their applicable materials include cement, sand and gravel aggregates and water, as well as admixtures added as needed.
