Concrete Presentation - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. concrete, also known as aerated concrete or lightweight concrete, is a versatile material consisting of a cement-based mortar mixed with at least 20% air by volume.
Concrete can be defines as a type of aerated lightweight concrete; it doesn't contain coarse aggregate (gravel) and can be regarded as an aerated mortar. Concrete can be produce by two methods (Inline Method and Pre- Method) where the liquid is added to slurry to form the .
The document defines concrete as a cement-based slurry with at least 20% entrained . It discusses the materials and manufacturing process of concrete and describes its key properties like compressive strength, thermal conductivity, drying shrinkage and fire resistance which vary according to density.
Aerated concrete, or concrete, is a lightweight concrete made by mixing cement, sand, and an aerating agent that creates air pockets. Using industrial wastes as partial replacements for fine aggregates can further reduce the density of aerated concrete while providing strength benefits and reducing non-recyclable waste.
used with either lightweight aggregates and/or admixtures such as fly ash, silica fume, synthetic fiber reinforcement, and high range water reducers (aka superplasticizers), has produced a new hybrid of concrete called lightweight composite concrete, or LWC.
Download ppt "ED CONCRETE SATYENDRA KUMAR MEENA PUSHPENDRA KUMAR MEENA". Introduction concrete is a type of porous concrete. According to its features and uses it is similar to aerated concrete. The synonyms are: Aerated concrete Lightweight concrete Porous concrete.
This document summarizes and compares aerated lightweight concrete types ed concrete and autoclaved aerated concrete (AAC). It discusses that ed concrete is produced through pre-ing or mixed ing methods using a agent to produce air bubbles.
Autoclaved aerated concrete is a lightweight, precast, concrete building material suitable for producing concrete masonry unit like blocks. AAC is one of the major achievements of the 20th century in the field of construction.

concrete is a lightweight concrete made by mixing cement paste with synthetic . It has a range of densities from 400-1600 kg/m3 depending on its intended use such as gap filling, partitions, or structural works.
