Precast concrete - Wikipedia precast stone is distinguished from precast concrete using a fine aggregate in the mixture, so the final product approaches the appearance of naturally occurring rock or stone. precast (panels) are only used within ranges of exterior and interior walls. Compressed in concrete and stone, creating a solid but maneuverable wall or face. By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to
Delivery, Handling and Storage storage and handling. Where possible, it is desirable to transport the precast elements into a manner which they can be lifted directly for erection or storage without much change in orientation and sequence. For example, wall panels can be transported using A-Frame type trailer in upright position. precast elements should be loaded and delivered with proper supports, frames, cushioning and tie-downs to prevent in- transit damage. Adequate packing or protection to the edges of
Discover - Universal Concrete Products 7. LAYOUT FLEXIBILITY. precast hollow-core planks and double tees provide long, clear spans, opening interior spaces to allow designers to maximize functional layouts. Loadbearing precast concrete wall panels can reach heights of 55 feet, while double tees can span 80 feet or more. 8. LOW MAINTENANCE. precast concrete panels require only periodic maintenance and inspection to maintain their reliability. The panels' fewer locations for moisture penetration prevent unsightly
