  • What Exactly Is Lightweight Concrete? | Specify Concrete

    Apr 25, 2019 · W hat Is Lightweight Concrete?. 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.

  • Lightweight Concrete for Pumping| Concrete Construction

    Lightweight Concrete for Pumping. The use of pumps for transporting and handling structural lightweight aggregate concrete is increasing. Lightweight aggregates are inherently porous, due to their method of manufacture, and will absorb greater amounts of water then conventional concrete aggregates. At atmospheric pressure this absorption may

  • New Publication Release: Pumping Structural Lightweight

    If aggregate is adequately and consistently presoaked, the problems of pumping lightweight are little different from those of pumping normal weight concrete. Some of the problems in pumping are: inconsistent mixes, slump loss, segregation, and need for excessive pump pressures. For each problem it would be possible to respond by adding water.

  • Lightweight Concrete - What Is Lightweight Concrete And

    A structural light-weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.

    ACI 211.1-74, allow reduction of the coarse aggregate content by as much as 10 percent to provide more workable concrete, when required, for pumping. Nevertheless, if the gradation is poor it should first be improved. How much reduction should be made can be determined only by experience with the aggregates and with the particular pump being used.
