Oct 03, 2013· Polymer concrete is a composite material. A graded mixture coarse and fine aggregates bound together by an appropriate organic resin system. Polymer concrete is a relatively lowcost composite material system that has been developed to be a technically viable alternative to porcelain for most high voltage electrical insulation applications.

Concrete frame structures are a very common or perhaps the most common type of modern building internationally. As the name suggests, this type of building consists of a frame or skeleton of concrete.
A structural lightweight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. The lightweight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.
Aerated Concrete. Aerated concrete production involves the addition of a ing agent such as aluminium powder to a mixture of cement, siliceousbased fine aggregate and water, to react with the lime in cement and create expansive reactions due to the formation of hydrogen gas, thereby producing a lightweight porous material. Aerated concrete is typically used in autoclaved blocks.

The use of lightweight concrete dates back to as early as the eighteenth century, and as advances in building and construction technology have increased, so has the use of lightweight concrete as the benefits of lighter dead load concrete have become apparent.
Portland concrete, the basic ingredient of concrete, is a closely controlled chemical combination of calcium, silicon, aluminum, iron and small amounts of other ingredients to which gypsum is added in the final grinding process to regulate the setting time of the concrete.
Usually consisting of lightweight aggregates, lightweight concrete can also be made using certain types of ing agents including aluminum powder. This gives the concrete a lower weight and lower density than traditional concrete. Lightweight concrete weighs between 65 and 100 lbs. per cubic foot.
