Light Weight Concrete

Reduced frame costs which we will discuss in greater detail later on in this post.

Light weight concrete. Concrete is considered to be lightweight is the density is not more than 2200kg m 3 the density of normal weight concrete is assumed to be between 2300kg m 3 and 2400kg m 3 and a proportion of the aggregate should have a density. Lightweight concrete may not be as structurally sound as traditional concrete but it can be useful in some projects where weight is more important than strength. The basic design for lightweight concrete is covered in eurocode 2 part 1 1 with section 11 having particular rules required for lightweight aggregate concretes. The lightweight aggregates used are usually expanded shale clay or slate materials that have been fired in a rotary kiln to give them a porous structure similar to volcanic rock.

Definition concrete which uses lightweight aggregates may consist of lightweight aggregates are used in ordinary concrete of coarse aggregate and sand clay foamed slag clinker crushed stone aggregates of organic and inorganic. Structural lightweight concrete has an in place density unit weight on the order of 90 to 115 lb ft 3 1440 to 1840 kg m compared to normalweight concrete with a density in the. To make this concrete combine 8 parts cement sand and lightweight aggregate with 5 parts water. Lightweight concrete costs more to produce.

Because lightweight concrete is typically thinner is made of different ingredients than traditional concrete floors can be up to 45 lighter regular concrete floors. But there s a catch. It can distinguish between structural lightweight concrete astm c 330 82a concrete used in masonry units astm c 331 81 and insulating concrete astm c 332 83.
