PUMICE LIGHTWEIGHT AGGREGATE (LWA) DESIGN ADVANTAGES: Reduces Dead Loads Reduces Lateral Forces Reduces Over Turning Forces Provides High-Friction Angle Controlled Gradations Free Draining Water Insoluable High Insulation Value Chemically Inert High Strength & Durability Easy to Handle and Install Readily Available Environmentally "Friendly" The Proven Solution For almost 50 years, Pumice Lightweight Aggregate (LWA) has been effectively used to replace heavy weight concrete products with lightweight concretes. Lightweight pumice aggregate can reduce the weight of precast by up to one-half. Where an "R" value is required, Pumice provides significantly greater thermal resistance when compared to regular weight concrete. This inert, durable, stable, free-draining and environmentally "friendly" lightweight aggregate is extremely easy to handle and provides economical long term solutions for precast challenges. The Material Pumice Lightweight Aggregate (LWA) has a long track record of quality and performance. Since its development in the early nineteen hundreds, Pumice structural lightweight concrete has been used extensively in high-rise buildings, commercial buildings, hospitals, schools, government housing and major shopping centers. Pumice aggregate is also used in precast, pre-stressed concrete, masonry and geo-technical applications. The quality of LWA results from a carefully controlled screening operation. The result is a high-quality, lightweight aggregate that is inert, durable, tough, stable, highly insulative, ready to meet stringent specifications for most structural and non-structural lightweight concrete projects.     California Lightweight Pumice, Inc., San Clemente, CA 92672
