Investigation of the Relationship between Compressive Strength and Hydrate Formation Behavior of Low-Temperature Cured Cement upon Addition of a Nitrite-Based Accelerator

When concrete is used for construction in cold-temperature regions, cold-resistant accelerators based on calcium nitrite (Ca(NO ) ) and calcium nitrate (Ca(NO ) ) are added to prevent early freezing damage. Although cold-resistant accelerators increase the early compressive strength and prevent earl...
