sand specifications for lightweight concrete
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.

Standard Specification for Lightweight …
This specification covers lightweight aggregates intended for use in structural concrete in which prime considerations are reducing the density while maintaining the compressive strength of the concrete. Procedures covered in this specification are not intended for stone control of concrete. Two general types of lightweight aggregates are covered by this specification: aggregates prepared by ...
lightweight concrete VS. sand-lightweight …
19.09.2005 · Am trying to discover the difference between lightweight concrete and sand-lightweight concrete. I ask because I am working on a stone 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.
Lightweight concrete
Batching of lightweight concretes is normally done from ready-mixed concrete producers. At low workabilities, the concrete can easily be placed by skip or chute. 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 ...

CHAPTER 3 - PHYSICAL PROPERTIES OF LIGHTWEIGHT AGGREGATE
Most lightweight concretes use a lightweight coarse aggregate 3/4 in. to #4 mesh (1/2 - #8) with ordinary sand, minus #4 mesh (minus 4.8 mm), however other combinations of LWA and natural aggregate are used. Aggregate for lightweight concrete masonry units are normally sized minus 3/8 in. (9.5 mm). This aggregate is usually the crushed variety ...
