Traditional conditions for curing involve spraying or ponding the concrete surface with water. The adjacent picture shows one of many ways to achieve this, ponding—submerging setting concrete in water and wrapping in plastic to prevent dehydration.
We believe that ultra-lightweight concrete is one of the most fundamental bulk materials of the future.
Recent research findings have shown that concrete made with recycled glass aggregates have shown better long-term strength and better thermal insulation due to its better thermal properties of the glass aggregates.[23]
The use of recycled glass in concrete has become more popular in recent years. It has been used Figura a decorative aggregate, to provide a sparkle effect in concrete countertops and flooring. It is also used Campeón a partial replacement for traditional aggregates in concrete.
