Resulting in excellent insulation and fire ratings Since the air bubbles are not connected, heat is forced to travel from air to cement matrix many times - losing more energy than if it could travel through connected cells (as with AAC Blocks). Some lightweight blocks have high water absorption (30-40%) so in-place performance can be very different from what the laboratory results would suggest K Block has low absorption therefore, its in-place performance is similar to lab results. No need for a bottom course of normal weight block (as seen in some projects when AAC blocks are used)ġ% water in a material adds 5% to that materials thermal conductivity value.AAC blocks have high water absorption (typically 30-40%), so moisture can pass through the wall easily - causing various and troublesome problems With low water absorption, K Block has no problems with moisture passing though the wall – so wall paper adhesion, electrical shorts, and moist walls are not potential problems. No Problems using K Block in areas of high humidity or rain.Can use normal mortar and normalīy using normal mortar/ plaster, contractors do not need special training or use special equipment to install K Block – they can use the same procedure/ equipment as they used for bricks/ normal weight blocks. This feature generates many excellent features and benefits This system is what we refer to as K Block Technology. Over the last fifteen years, K Block Technology has modified the CLC method, designed our own production equipment and foaming agent, and developed a unique and complete production system for making lightweight concrete. The key issue was lack of good production equipment, strong air bubbles that could take the rigors of a plant process and a lack of a production system/ quality control procedures. While CLC has been uses in the world for more than 60 years, it has mostly been used for roof insulation and floor toppings. Instead, the aggregate and some (or all) of the sand is replaced with very small air bubbles. CLC was first developed during the 1920’s and describes a material that is made with the same materials as concrete - namely: cement, sand (sometimes), and water but no coarse aggregate. K Block Lightweight Concrete is uses a production method based on cellular lightweight concrete (CLC). It is these small air bubbles/ pores in combination with our own specially designed production equipment that give our lightweight material its unique set of properties This “foam” is then blended with a cement slurry or cement/ sand mix. The small, strong air pores/ bubbles in K Block Lightweight Concrete are made using a proprietary foaming agent (K Block Foaming Agent) which flows through a foam generator - creating mechanically manufactured bubbles. K Block Lightweight Concrete is an engineered low-density material made from cement, sand, water, and millions of small air pores (bubbles).
