What lightweight aggregates can be used in concrete for portable outdoor trash cans?
When constructing portable outdoor trash cans, using lightweight aggregates in concrete is essential to reduce weight while maintaining durability. Key aggregates include expanded clay, which offers excellent strength and insulation; pumice, a natural volcanic rock that provides low density and good workability; and perlite, known for its lightweight and fire-resistant properties. These materials help create concrete that is easy to move yet resistant to weathering and impacts, making them ideal for public spaces, parks, and residential areas. By incorporating such aggregates, manufacturers ensure the trash cans are portable, long-lasting, and environmentally friendly, enhancing usability without compromising on structural integrity.
