Lightweight Cellular Concrete Classes. The four general classes of lightweight cellular concrete delineated by maximum as-cast density and minimum compressive strength are given in Table 1. If the class of lightweight cellular concrete is not specified in the contract, the class to use shall be as directed by the Engineer. Table 1.

The present study presents a methodology to design ultra-lightweight concrete that could be potentially applied in monolithic concrete structures, performing as both load bearing element and thermal insulator. A particle grading model is employed to secure a densely packed matrix, composed of a binder and lightweight aggregates produced from recycled glass. The developed ultra-lightweight ...

Lightweight Concrete:- Concrete with porous aggregates is now the most commonly used type of lightweight concrete. Its density does not exceed 180 kN/m² because of the use of light and porous aggregate. The light concrete not only results in saving the dead weight of the structure but has better insulation against heat and sound.

A simple recipe for basic lightweight concrete is to combine 8 parts sand, 8 parts cement and 8 parts perlite to 5 parts water. Alternatively, you can follow the directions for most traditional concrete mixes, replacing the required gravel with half the weight of your chosen lightweight aggregate as they tend to weigh about half of what the ...

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).

Density of conventional concrete varies from 2400-2500 Kg/m3. But. the density of light weight concrete is in between 300-1900 Kg/m3. How great difference !!!. • As per RILEM, the light weight concrete committee. "The LWC is a concrete capable 0f hardening, to a mass having. oven dry density not more than 1800 Kg/m3 ".

concrete, principally about the effects on fracture energy. Some research (Strange and Bryant 1979, Nallathambi, Karihaloo, and Heaton 1984) has shown that there is an increase in fracture toughness with an increase in aggregate size. However, Gettu and

Green Concrete Seminar and PPT with pdf report: Green Concrete is that type of concrete that is used to create the construction materials having a lesser effect on the environment. This version of concrete is made up of a mix of industrial waste and inorganic polymer. The most commonly used way to produce green concrete is by using industrial waste products such as fly ash, blast …

Zhenhai Guo, in Principles of Reinforced Concrete, 2014. 11.5.2 Light-weight concrete. 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 ...

Hence light weight concrete made using different types of light weight aggregate will have different densities. Concrete produced by using expanded perlite or vermiculite will have a low density of the order of 300 kg/m 3, whereas by the use of expanded slag, Sintered fly ash or bloated clay etc. a concrete having density as high as 1900 kg/m ...
