Lightweight Concrete: Types, Properties, Merits & Demerits

Introduction to lightweight concrete: Light concrete is made of lightweight aggregate, it is also called foam concrete. Since this cement consists of lightweight aggregates, it is used in coarse aggregates and sand, clay, foamy slag, clinker, and crushed stone, aggregates of organic and inorganic.. This concrete saves 15 to 20 % in the cost of construction of floors and roofs.
