In ancient times, lime was the primary material used in construction. Over the years, as construction evolved, cement and steel became the dominant materials. Today, the construction industry continues to innovate, introducing advanced technologies to improve quality, efficiency, and craftsmanship. Traditionally, masonry work relied on stones, bricks, and concrete blocks, but the introduction of lightweight AAC blocks has transformed modern construction. Just as lime was once replaced by cement and sand, AAC blocks now lead the way, offering superior performance and aligning with the demands of modern construction practices.
