How are concrete blocks made in the USA?

Concrete blocks by Aichen are manufactured using a specific blend of aggregates, cement, and water. The process involves mixing these components, molding them, and then curing the blocks. Aichen employs precise proportions, typically about 1:2:4 for cement, sand, and gravel, ensuring consistency and strength.

Blocks are mechanically vibrated to remove air pockets and achieve optimal compaction. Once cast, they undergo curing, often using steam or by being kept in a controlled environment, to achieve desired strength and durability, usually reaching a compressive strength of 1500 to 3000 psi.

For comparison, Quikrete uses similar manufacturing processes but may vary in specific ratios and curing techniques depending on the product. Another example, BASF, offers specialized additives to enhance block properties. These standard practices ensure that Aichen and others produce reliable building materials for construction needs.
