Abstract: Materials and methods for a rapid and effective way to create a carbon negative self-healing construction material are described. The construction material uses sand aggregates, a trace amount of catalyst, a small dosage of scaffolding material with a crosslinking agent, and a calcium source. The curing is performed at a high temperature for a short period or at room temperature for a long period. The catalyst-driven method to bridge the sand particles results in a dense, stiff, strong, and tough structural material, which upon exposure to calcium source and CO2 heals itself repeatably.
