Curing in concrete works
WebInternally cured concrete utilizes pre-wetted absorbent materials that contain moisture. This moisture is dispersed throughout the concrete when the internal humidity of the concrete drops below 100% to keep cement paste saturated, which leads to greater hydration of cement. As a result, the strength and durability of concrete are improved. WebNov 10, 2024 · If the concrete freezes, the curing process may take longer or result in uneven curing or cracks. Freezing can reduce concrete strength by up to 50%. A …
