DELVOcrete 29 admixture is a unique, non-chloride chemical admixture that controls the dynamics of cement hydration by suspending the hydration process for hours or even days without affecting the quality of hardened shotcrete. DELVOcrete 29 admixture is a liquid admixture. When dispensed into wet or dry mixes at the batching plant, it fully stabilizes the hydration process by forming a protective barrier around the cement particles.
