Pumping Structural Lightweight Concrete Concrete ...

THE LIGHTWEIGHT CONCRETE MIX. The first word of caution is that the concrete mix, no matter how well it is designed, should be field tested to confirm its pumpability before the project starts. One difference between the mix proportions of lightweight and normal weight concrete for pumping is in the amount of fine aggregate used.

2021-11-16  Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb/ ft3 (1440 to 1840 kg/m3) compared to normalweight concrete with a density in the range of 140 to 150 lb/ ft3 (2240 to 2400 kg/m3). For structural applications the concrete strength should be greater than 2500 psi (17.0 MPa).

Pumping of Lightweight Concrete Using Non-Presoaked ...

Date: 8/1/1988. Abstract: Focus is the study of basic properties of the low water-absorption lightweight aggregate and the water-absorption reducing agent that were developed to make the pumping of lightweight concrete using non-presoaked lightweight aggregate possible. The water absorption of the low water-absorption aggregate was extremely small.

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.
