Lightweight Concrete Produced Using a Two

The conventional method of producing lightweight concrete takes into account the workability and aggregate segregation of the fresh mix. Therefore, conventional mix design is limited by the retainable volume fraction of lightweight aggregates, and consequently the achievable lowest density of lightweight concrete is also limited.

StoneCoat Cast Profiles. StoneCoat is a highy engineered and tested concrete coating that is cast 1/2 thick over an EPS core to create a revolutionary lightweight cast stone product. StoneCoat Cast Profiles offer the aesthetic of limestone, cast stone, or GFRC at a significant cost savings. Because StoneCoat cast profiles are 10-15% the weight of cast stone, savings can be realized in Get price

High Density Concrete

High Density Concrete. High density concrete is a concrete having a density in the range of 6000 to 6400 kg/cu.m. High density concrete is also known as Heavy weight concrete. High density concrete is mainly used for the purpose of radiation shielding, for counterweights and other uses where high density is required. The high density concrete has a better shielding property, so that it can Get price

Lightweight Concrete

The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less. The lightweight aggregates used are usually expanded shale, clay, or slate materials that have been fired in a rotary kiln to give them a porous structure, similar to volcanic rock. Get price
