Sand specifiions for lightweight concrete

Use sand lightweight concrete, as noted on the plans, that meets the requirements of this Special Provision. Sand lightweight concrete is composed of portland cement, fine aggregate, lightweight coarse aggregate, water, and admixtures. Provide sand lightweight concrete that complies with the applicable requirements of Sections 420, 1000, and

    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

I ask because I am working on a job that the specs call for sand-lightweight concrete. The concrete is light weight, but this is due to the aggregate. The sand, as near as I can tell, is regular manufactured sand

    Mar 15, 2010 Aerated concrete is a lightweight, cellular material consisting of cement and/or lime and sand or other silicious material. It is made by either a physical or a chemical process during which either air or gas is introduced into a slurry, which generally contains no coarse material. Aerated concrete used as a structural material is usually high

    Apr 01, 2015 With standard structural concrete the aggregate used is sand and stone. With structural lightweight concrete a mix of shale, slate, slag and clay are used and, with this mix, the aggregate is fully saturated prior to mixing. The end result of the structural lightweight mix is a deck that can be 20-25% lighter than standard structural concrete
