Light Weight Concrete - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. Lightweight concrete has a density between 300-1850 kg/m3, reducing dead load on buildings. It is produced by replacing normal aggregates with lightweight aggregates like pumice or fly ash, introducing air bubbles through aeration, or …
Lightweight concrete has a lower density than ordinary concrete due to the use of lightweight aggregates. It has strengths between 7-40 MPa, improved workability, thermal insulation, and water absorption. Lightweight concrete exhibits higher moisture movement and fire resistance compared to ordinary concrete.
4. Introduction: Light weight concrete is a special concrete which weighs lighter than conventional concrete. Density of this concrete is considerably low (300 kg/m3 to 1850 kg/m3) when compared to normal concrete (2200kg/m3 to 2600kg/m3). Basically there is only one method for making concrete light i.e by INCLUSION of air in concrete. . This is achieved in …
Lightweight ConcreteLightweight Aggregate Concrete. Definitions: Lightweight concrete has a maximum density of 1900 kg/m3 and is achieved by using low-density aggregates. Intermediate-density concretes, where part or all the normal-density coarse aggregates are replaced with structural-grade low-density aggregates, have densities of 1900-2200 kg/m3.

The effect of water quality on the compressive strength of concrete was evaluated in this study. A total of 100 concrete cubes (150 x 150 x 150 mm) were cast using a mix ratio of 1:2:4. The hardened concrete cubes were de-moulded 24 hours after the cubes were cast and were submerged carefully in a curing tank filled with water.
