ResumoThis chapter focuses on several applications of lightweight aggregate concrete (LWAC). Lightweight aggregates are used as insulating fill within the cavities of concrete masonry units to decrease the U value of the wall. The aggregates can be used to backfill after sewer and water lines have been installed in northern regions to reduce frost penetration. Lightweight aggregates, because of their ability to absorb water, have found extensive use in horticulture applications such as in a soil addition to fill over underground parking garages. The lightweight aggregate concrete has been extensively used in ship building because of its low density. The durability of the nonair-entrained LWAC containing fine aggregates after 80 years of exposure in the marine environment is excellent. There is limited deterioration due to freezing and thawing, and the exposed surfaces are relatively crack free.
