The core concept behind cement pavers is their interlocking design, which distributes weight evenly and creates a stable surface. This interlocking mechanism is crucial for preventing shifting and cracking, common issues with poured concrete. Advanced principles involve understanding soil compaction, base preparation, and proper drainage to ensure the longevity of the paved surface. The compressive strength of cement pavers is a critical factor, measured in pounds per square inch (PSI). Pavers used for driveways typically require a higher PSI than those used for patios or walkways. The manufacturing process involves mixing cement, aggregates (sand and gravel), pigments, and water in precise proportions. This mixture is then poured into molds and subjected to vibration and pressure to achieve optimal density and strength. Curing is a crucial step, where the pavers are allowed to hydrate and harden under controlled conditions.
