One of our more sophisticated aggregates possess special light weight properties creating a much lighter ready mix design. Lightweight aggregate, as the name suggests, reduces the weight of the finished product, and it provides concrete with similar or superior physical performance characteristics compared with normal weight concrete.
Fire ratings for products that use this lightweight aggregate, such as concrete blocks, are 30% to 50% higher. As for thermal insulation, concrete block made with this aggregate has roughly 2.5 to 4.8 times the thermal efficiency of normal-weight units. Also, a block that uses this aggregate absorbs 45% of incident noise compared with a normal-weight concrete block, which absorbs 27% of incident noise.
