What is Lightweight Concrete? -Types, Uses and Advantages ...

1. Lightweight Aggregate Concrete. In the early 1950s, the use of lightweight concrete blocks was accepted in the UK for load bearing inner leaf of cavity walls. Soon thereafter the development and production of new types of artificial LWA (Lightweight aggregate) made it possible to introduce LWC of high strength, suitable for structural work.

Aggregates for Concrete

The approximate bulk density of aggregate commonly used in normal weight concrete ranges from about 1200 kg/m3 to 1750 kg/m3 (75 lb/ft3 to 110 lb/ft3) while lightweight concrete aggregates range from 560 kg/m3 to 1120 kg/m3 (35 lb/ft3 to 70 lb/ft3), and heavyweight aggregates is typically over 2100 kg/m3 (130 lb/ft3).

Lightweight-Aggregate Concrete for Structural Use

Concrete mixes were designed to produce compressive strengths of 3000 psi and 4500 psi with each aggregate, and 7000 to 10,000 psi with three selected aggregates. Comparing the various concretes on the basis of equal compressive strengths, normal weight sand-and-gravel concrete showed somewhat superior performance in most tests.
