Manufacture of Concrete Masonry Units

The process of manufacturing concrete masonry units begins by mixing stiff concrete composed of Portland cement, aggregates, and water. This mixture is then poured into metal molds. To ensure the concrete settles uniformly and to avoid separation of its components, the mixture in the molds is subjected to vibration. Shortly after, the still-wet ...

Manufacturing concrete masonry units involves pouring stiff concrete, comprising Portland cement, aggregates, and water, into metal molds.

This is followed by vibrating, and soon after, the wet blocks are demolded onto a rack.

The wet blocks are then carried to either a steam kiln for steam curing or an autoclave for high-pressure ...
