What is medium density Blockwork?

If this isn’t the case, blockwork types are separated into three categories. Dense aggregate – with a dry density of 1850-2300kg/m3. Lightweight aggregate – with a dry density of 1350-1600kg/m3 (otherwise known as medium density) Aircrete – with a dry density of 600-800kg/m3.

Does cinder block have an R-value?

Concrete block makes a cost-effective and structurally sound wall, but it has little thermal resistance. Depending on the density of the blocks, an 8-inch thick block wall without any other type of insulation has a thermal resistance value between R-1.9 and R-2.5.

What is the density of Blockwork?

Dense aggregate blocks have a density in the range 1800 – 2100 kg/m3, while lightweight aggregate blocks (otherwise known as Medium Dense) have with a density in the range 650 – 1500 kg/m3.

What is a high density block?

High-Density Concrete Blocks provide protection for a range of scenarios. They are made to site-specific spacial requirements for gamma and neutron radiation with five standard densities. In new construction or room upgrades, the interlocking design of our HD Block ensures shielding integrity.

What is the R-value of an 8 inch block?
