lite weight concrete

There are three different lightweight concrete type divisions in terms of strength range, which are low-density concretes (0.7–2.0 MPa), moderate-strength concretes (7–14 MPa) and structural concretes (17–63 MPa).

Lightweight aggregate concrete can be used for the construction of partition walls and panel walls in frame structures. It can be used to create general insulation of walls. It is also used to get surface rendered for external walls of small houses. It can be used for reinforced concrete.

Lightweight Concrete reduces the dead loads resulting in savings in foundations and reinforcement. Lightweight Concrete improves the thermal properties of a building. Lightweight Concrete improves the fire resistance of a building.

Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), and other terms is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar.

Lightweight concrete is also specified because of its tendency to crack less. The reduced cracking can be linked to several properties found at the interfacial transition zone (ITZ) where the aggregate meets the cementitious paste.Is lightweight concrete more expensive than normal weight? Yes and no.... The material unit cost of lightweight concrete is typically higher than that of normal-weight concrete, but the unit cost usually is more than offset by the overall reduction in concrete volume and steel tonnage for the structural system.Using less sand can make the product lighter, but it can also make the concrete weaker structurally. A simple recipe for basic lightweight concrete is to combine 8 parts sand, 8 parts cement and 8 parts perlite to 5 parts water.An important question always is how much this will cost. Lightweight aggregate concrete is about $20 to $30 per cubic yard higher than a normal weight mix. For internal curing, you may only be replacing about a third of the aggregate with lightweight so it may only add an extra $10 per cubic yard.Lightweight concrete is characterized by good compressive strength, durability and the most important advantages – low density and improved properties of thermal conductivity. Typical lightweight concrete aggregates are expanded clay or shale, natural porous materials like vermiculite or pumice.Concrete material made of lightweight aggregates is called lightweight aggregate concrete, while material made from a cellular matrix is generally called foamed concrete because of the pores introduced by a foaming agent.No-fines concrete is obtained by eliminating the fine material sand, from the normal concrete mix. The single-sized coarse aggregates are surrounded and held together by a thin layer of cement paste giving strength of concrete. The advantages of this type of concrete are: Lower density.Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and therefore generally provides increased fire resistance.Perlite concrete mixed at a ratio of 1 part cement to 6 parts perlite has an insulation value, or "k" value, of 0.64 and a compressive strength of 125 to 200 pounds per square inch. At a ratio of 1 part cement to 4 parts perlite, you achieve a "k" value of 0.83 and compressive strength of 350 to 500 pounds per inch.Artificial aggregates produced from natural raw materials determine the highest environmental impact in concrete material. Lightweight aggregates produced from industrial waste raw materials provide environmental benefits due to the avoided impacts.30-Aug-2016The only drawback of lightweight concrete is that the depth of carbonation i.e. the depth within which corrosion can occur under suitable conditions is nearly twice than that of normal concrete. Structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³.... Nevertheless, a higher compressive strength of 7000 to 10,000 psi can be attained with lightweight concrete.
