11.20 Lightweight Aggregate Manufacturing

Lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block, structural concrete, and pavement. The Standard Industrial Classification (SIC) code for lightweight aggregate manufacturing is 3295; there currently is no Source Classification Code (SCC) for the industry.

LIGHTWEIGHT AGGREGATE CONCRETE: EFFECT OF AGE AND

Lightweight aggregate concrete may be very different from normal weight concrete from this point of view. The properties mainly depend on the properties of the lightweight aggregate like particle density, water absorption capacity. The aim is to study the impact of the time under water storage on compressive strength and fracture tests results.

What is Lightweight Concrete ? Types & Uses -

Conventional aggregates in the concrete can be replaced by cellular porous aggregates. (Lightweight aggregate concrete) The air or gas bubbles can be inserted in concrete (Aerated concrete). During the preparation of concrete, sand should not be used and it should be omitted. (No- fines concrete). Types of Lightweight Concrete 1. Lightweight

Lightweight Concrete - What Is Lightweight

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.

Shear Behavior of Lightweight Slag Aggregate

Lightweight self-consolidating concrete (LWSCC) has evolved to combine the excellent benefits of self-consolidating concrete (SCC) and lightweight concrete (LWC). However, investigation on structural performance of LWSCC-made structural components is quite limited.

Lightweight Aggregate Concrete - an overview

Light-weight (aggregate) concrete (ρ ≤ 1900 kg/m 3) is of smaller modulus of elasticity, sharp stress–strain curve, and fails suddenly (see Section 4.2). The mechanical behavior of the reinforced beam of light-weight concrete is similar to that of ordinary concrete, but shows larger deflection, wider crack, and quicker failure.

Lightweight Concrete: Light weight aggregate

Most of the lightweight concrete is made with light weight aggregates. Lightweight concretes strengths is generally in the range of 44 psi (0.3 N/mm2) to 5800 psi (40 N/mm2) and cement content in the range of (13 lb/ft3) 200 kg/m3. The density of aggregate plays a vital role in the strength of lightweight concrete.

Lightweight Concrete: Types, Properties, Merits

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 Aggregate Concrete - Properties,

Lightweight aggregate concrete is prepared by using lightweight aggregate or low density aggregate such as volcanic pumice, clay, slate, shale, scoria, tuff and pellite. Concrete is considered to be lightweight is the density is not more than 2200 kg/m 3, when compared to normal concrete which is 2300-2400 kg/m3 and a proportion of the aggregate, should have a density of less than 2000 kg/m 3 .
