lightweight foamed concrete while contributing to sustainable development of building materials. This experimental study is aimed to investigate the effects of incorporation of eggshell on its water absorption and strength properties of lightweight foamed concrete (LFC) with density of 1300 kg/m3 in .
Mar 01, 2018· The required properties of the lightweight concrete will have a bearing on the best type of lightweight aggregate to use. If little structural requirement, but high thermal insulation properties, are needed then a light, weak aggregate can be used. This will result in relatively low strength concrete. Foamed concrete
May 24, 2017· LWAC is the popular type of lightweight concrete, in which lightweight aggregates are used. The lightweight aggregates are relatively new materials. These have a unit weight up to 12kN/m3. The LWA can be either natural or artificial or manufactured. The natural aggregates include volcanic cinder, dolomite or pumice.
Moreover, many other properties of concrete can be deduced from the strength of concrete. Although in practice, concrete is subjected simultaneously to a combination of compressive, shearing and tensile stresses in two or more directions, the 28days uniaxial compressive strength of concrete determined by a standard compression test is accepted universally as a general index of concrete strength .
In this study, an attempt has been made to improve the lowered mechanical properties and young's modulus of light weight aggregate concrete by the usage of mineral admixture Silica Fume 10% by weight of cement (from literature) to the structural grade light weight aggregate concrete.

lightweight aggregates, including pumice, expanded shale and bottom ash. The characteristics of these lightweight aggregates are correlated with thermal conductivity and resistance of concrete slabs made with the lightweight aggregates. Versaliteª is a manufactured lightweight aggregate, which is currently produced from spray dryer ash
marized the thermal properties of lightweight concrete, and reported that density and moisture content are the main factors affecting the thermal conductivity, while the mineralogical properties of aggregate material can affect the thermal conductivity of LWC up to 25% under a .

Studies On Properties Of SelfCuring Concrete Using PolyEthylene Glycol Basil M Joseph1 (Assistant Professor, Civil Engineering department, SNGCE/ University,Kadayirippu) Abstract: Curing of concrete is maintaining satisfactory moisture content in concrete during its early stages in order to develop the desired properties.
. Zsing concrete with a lower density is possible. Therefore, result in significant benefits. The use of concrete with a lower density permits construction on ground with a low loadbearing capacity. Furthermore, with lighter c oncrete, the framework can withstand a lower pressure, when compared to normal weight concrete.

Structural Lightweight Concrete is a versatile building material typically with unit weights from 90 to 125 pounds per cubic foot and compressive strengths from 2,500 psi to more than 8,000 psi. Since it is generally 20% to 40% lighter than normalweight concrete, a structure's dead load can be reduced, its foundation costs lowered, and it's concrete and rebar lessened.
