Lightweight concrete can be prepared either by injecting air in its composition or it can be achieved by omitting the finer sies of the aggregate or even replacing them by a hollow, cellular or porous aggregate. Particularly, lightweight concrete can be categoried into three groups i No-fines concrete.

P.L. Owens, J.B. Newman, in Advanced Concrete Technology, 2003. 7.1 Introduction, definitions and limitations. Lightweight-concrete is defined by BS EN 206-1 as having an oven-dry density of not less than 800 kgm 3 and not more than 2000 kgm 3 by replacing dense natural aggregates either wholly or partially with lightweight aggregates. Although excluded from this Standard this range of.
Apr 01, 2016nbsp018332Cellular Lightweight Concrete has been long used for slabs and road construction, but getting the industry to look at it as a building block for structural walls has been a challenge. CLC, and its cousin Aerated Autoclaved Concrete block AAC, reduce masonry partition wall weight and allow fast construction. The latter is expensive because of.
Mar 06, 2007nbsp018332The use of lightweight concrete as a roof decking and insulation system has expanded in the past five years. Increased usage can be attributed to the recent industry-wide insulation shortages and delamination deficiencies. The increase can also be attributed to the economic and environmental advantages that lightweight insulating concrete LWIC provides in roof assemblies.
Aerated concrete is one of the light weight concrete. It is a mixture of water, cement and finely crushed sand. Aerated concrete is obtained by introducing gas bubbles into the plastic mix of cement and sand mortar. The product obtained is cellular in structure containing voids of.
Lightweight concrete based on miscanthus biomass has several advantages over mixtures based on sand or gravel, including better insulation properties, improved protection against overheating in summer, and high durability.

Lightweight-concrete is defined by BS EN 206-1 as having an oven-dry density of not less than 800kgm3 and not more than 2000kgm3 by replacing dense natural aggregates either wholly or partially with lightweight aggregates. Although excluded from this Standard this range of densities can be achieved if the concrete is made with most dense natural aggregates but in such a way that excess air is incorporated as, for example, in no-fines, aerated or foamed concrete.
Lightweight aggregate is defined in BS EN 13055 as any aggregate with a particle density of less than 2.0Mgm3 or a dry loose bulk density of less than 1200kgm3. These properties mainly derive from encapsulated pores within the structure of the particles and surface vesicles. For structural concrete suitable aggregates should require a low cement paste content and have low water absorption.
The most appropriate method of assessing particle density in structural concrete is to compare the density of the particle to that of typical natural aggregate, e.g. with a reference particle density of 2.6Mgm3. The minerals comprising the solid structure of most aggregates, whether lightweight or not, have densities close to 2.6Mgm3, but it is the air within the structure of an aggregate that enables compacted structural concrete to be less than 2000kgm3.
Lightweight concrete, also known as EPScrete expanded polystyrene concrete, is a material widely used in the building of environmentally quotgreenquot homes. The substance is often made using small Styrofoam balls as a lightweight aggregate instead of the crushed stone that is used in regular concrete.

Cellular Lightweight Concrete Seminar Report, PPT, The density is considerably reduced by using fly ash based cellular lightweight concrete than normal concrete and at the same time, the strength is not affected by appropriate design mix. When we use this type of concrete we achieve large volume by less amount of concrete.
