Lightweight Concrete: Types, Properties, Merits & Demerits

Jun 03, 2020· 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 roots.

Lightweight Concrete What Is Lightweight Concrete And

The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less. 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.

What is Lightweight Concrete? -Types, Uses and Advantages

Mar 15, 2010· Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).

Presoaking Lightweight Aggregate| Concrete Construction

May 01, 2001· In his book Properties of Concrete, A.M. Neville suggests producers should expect a wide range of soaking times based upon aggregate types. ôThe 24-hour absorption of lightweight aggregate ranges from 5% to 20% by mass of dry aggregate, but, for good quality aggregate for use in structural concrete, it is usually not more than 15%,ö he writes.

Advantages and Disadvantages of Lightweight Concrete

Jun 29, 2020· These vary from lightweight aggregate concrete, foamed concrete, or Autoclaved Aerated Concrete (AAC). The aggregates used in AAC are extremely fine, even smaller than a grain of sand. This composition makes AAC highly suitable for pre-casting and reshaping. AAC structures are so soft that they can be hand-sewn and pierced by nails or screws.

Structural Lightweight Concrete — What, why, & how

Lightweight concrete can be manufactured with a combination of fine and coarse lightweight aggregate or coarse lightweight aggregate and normal weight fine aggregate. Complete replacement of normal weight fine aggregate with a lightweight aggregate will decrease the concrete density by approximately 10 lb/ft3 (160 kg/m3).

Types of Light Weight Aggregates Materials Concrete

The strength of concrete made from expanded clay or shale aggregate is higher than concrete made with other light weight aggregates. iv. Perlite: It is a glassy volcanic rock found in America, Italy and Ulster etc. When it is heated rapidly to a tem­perature of 900 to 1000°C, it expands due to the evolution of steam and forms a cellular material.
