Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. Structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³. This makes lightweight concrete ideal ...

Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process. The inlet material (the raw product) advances from the part where the ...

The concrete vibrator head will go in between rebar columns and should require the head to be submerged for 5 to 15 seconds. The vibrator head should not be forced down, it should only submerge itself by its own weight. Once the air bubbles in the spot being vibrated have stopped rising, slowly remove the head from the concrete and move on to ...

Share. Lightweight concrete is a mixture made with lightweight coarse aggregates. Low-weight aggregates such as shale, clay, shale, slate, volcanic pumice, ash, or perlite are used to reduce the density. Lightweight concrete is a special type of concrete made to be used for special purposes. It is not commonly used as normal-weight concrete.
