LIGHTWEIGHT CONCRETE BLOCKS OFFER AN ECO-FRIENDLY , COST-EFFECTIVE ALTERNATIVE
CemteQ ’ s new lightweight concrete blocks offer an eco-friendly , cost-effective walling alternative to traditional clay and concrete bricks and maxi bricks . Made with specially treated , re-engineered polystyrene beads as an aggregate replacement together with cement , perlite , micro-fibres and admixtures , these lightweight yet robust concrete blocks are then precision cut to size .
One of the primary advantages of polystyrene concrete blocks is their high thermal insulation value . With a thermal conductivity value of 0.1335 W / m · K , the 650kg / m 3 blocks are highly energyefficient and can significantly reduce heating and cooling costs . They are also durable , resistant to moisture and fire and can withstand reasonable loads without cracking or breaking .
Another advantage of these polystyrene concrete blocks is their environmental sustainability . They are made using recycled polystyrene which is a common waste material that would otherwise end up in landfills . They utilise 86 % recycled components and have a carbon footprint 22 % that of clay brick and 14 % that of low strength conventional concrete . By using this and other recycled materials including slag in the mix , construction projects can significantly reduce their environmental impact .
They pass the ‘ knock-test ’ and are available in a 100mm , 140mm and 200mm thicknesses , making them suitable for both residential and commercial projects . Chasing and fixings are also generally simpler than conventional brick and mortar .
In addition to their energy efficiency and sustainability , polystyrene concrete blocks and panels are also easy to install and require little maintenance . They can significantly reduce construction time and costs while providing long-lasting and durable results .
CemteQ is committed to developing , manufacturing and distributing smart , world-class building materials that contribute meaningfully to the way people build and live . They offer high quality exfoliated perlite and perlite-cement blends as well as recycled polystyrene blends for lightweight , thermal insulation applications in the building industry . www . cemteq . co . za
