Lightweight concrete

Pumping lightweight concrete can be achieved, but care needs to be taken so that the concrete mix doesn’t separate. For pumpable mixes it is usual to use a natural sand, i.e. not to have a lightweight aggregate for the fine portion of the mix and to have a high workability so that increased pump friction and blockage is avoided. This is achieved with the use of admixtures. Over vibration of ...

Lightweight aggregates Aggregate Industries

Lightweight aggregates. Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,100°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural aggregate.

Pumpable concrete starts with the aggregate. It is the combined gradation of the aggregates and their residual moisture absorption that are most important. A pumpable lightweight mix may differ from one that is not pumpable in having a higher plastic unit weight, especially if more natural sand is used. It may have a higher slump as it enters the pump and its dry unit weight at 56 days is ...
