What is Lightweight Concrete? 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 inplace density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).
Lightweight highperformance concrete (LWHPC) with a pozzolan (fly ash or silica fume) or slag cement is expected to provide high strength and high durability with reduced dead load. Reduced dead load may provide savings in the substructure elements.
High Performance implies an optimized combination of structural properties such as strength, toughness, energy absorption, stiffness, durability, multiple cracking and corrosion resistance taking into account the final cost of the material and above all, the produce manufactured.
The key difference between lightweight and heavyweight concrete is the density of the aggregate. Lightweight concrete is made using aggregate whose density is less than 2,100 kilograms per cubic yard (or 131 pounds per per cubic foot), while aggregates with greater densities give rise to socalled heavyweight concrete.
concrete and structural lightweight concrete. In the present work, HPLC was produced from totally local materials (Metakaolin and Porcelinite). An experimental part had carried out to investigate the effect of increasing lightweight aggregate volume on timedependent deformations of high performance lightweight concrete.
There is no cutting required, and there is no concern about the shape/sloping of the structure. Nearly the lightest of all fills, Cellular Concrete is simply the most cost effective solution. When designed for a mix design density of 2527 pcf, the structural reinforcing rarely changes due to the weight of this fill over other alternatives.
8 0–P R E CAS TW .HIG ON M HIGH CONCRETE 3 Architectural Facade Systems from High Concrete Architects have chosen precast concrete architectural facades for almost half a century because they offer exceptional aesthetic and structural versatility, speed of enclosure, and durability.

Lightweight concrete presents a number of benefits to the building industry–lighter weight on a building's structural load, greater sound absorption, better shock absorption and flexibility, improved insulation values–when compared to standard concrete blends.
Apr 18, 2012· This paper determines mix proportions of highstrength structural lightweight concrete (HSSLWC), which reduces the weight of concrete by using expanded aggregate clay (Leca). In order to produce HSSLWC, mineral and chemical admixtures have been used along with limestone that reduces porosity and increases strength.

May 02, 2005· The general objective of this research was the construction and evaluation of a bridge using highperformance lightweight concrete (HPLWC). The resulting bridge over the Chickahominy River near Richmond, Va., consists of 15 prestressed American Association of State Highway and Transportation Officials (AASHTO) Type IV girders made of HPLWC with a density of 1,920 kg ∕ m 3 .
Lightweight concrete can be applied in a number of ways, such as a reduction in selfweight of structures with smaller cross sections. The lightweight concrete developed could be a suitable material for highrise buildings, with a number of advantages: cost saving due to extra insulation not being required, more flexibility for architects and structural engineers when designing buildings ...
