Am trying to discover the difference between lightweight concrete and sand-lightweight concrete. 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.

Equilibrium density is a standardized value intended to represent the approximate density of the in-place concrete when it is in service. Project specifications should indicate the required equilibrium density of the lightweight concrete. Equilibrium density is defined in ASTM C 567, and can be calculated from the concrete mixture proportions.

ABSTRACT. Lightweight Cellular Concrete (LCC) (also named as concrete or gas concrete) is a special construction material, which typically consists of Portland cement, water, and air voids created by a agent. This material has been increasingly used as a backfill material for geotechnical applications in recent years.

Understanding Structural Lightweight Concrete. Structural lightweight concrete is defined as having a 28 day compressive strength in excess of 2,500 psi and a unit weight ranging from 85 or 90 pcf to 115 pcf. Generally speaking, concrete in this range of strength and weight is produced with expanded shales, clays, slates, and slags.

The density of the OPS concrete was maintained in the range of 1600–1700 kg/m 3, and the compressive strength was in the range of 16–24 MPa, satisfying the requirements of ASTM and ACI for structural lightweight concrete [175]. The increase in leads to more pores and crack paths, weakening the bonds between the OPS …

2. Materials and methods. LWA having a unit weight of 1536 kg/m 3 and limestone crushed aggregate having a maximum size of 19 mm, procured from a local aggregate crushing facility were used as LWA and NWA, respectively. Locally produced crushed stone sand having fineness modulus of 4.18 was used as fine aggregate.

Aggregates for concrete must conform to Section 90-1.02C "Aggregates," of the Standard Specifications unless specified otherwise. These requirements include durability and cleanness testing requirements for coarse aggregates, and organic impurities and sand equivalent testing requirements for fine aggregates.
