Cement
The cement-making process, from crushing and grinding of raw materials, through roasting of the ground and mixed ingredients, to final cooling and storing of the finished product.
Low temperatures have an adverse effect on freshly poured concrete. While the setting and hardening of cement is a continuous process, environmental conditions like temperature are critical to the material's final strength.12
When temperatures are low, the chemical reactions required for concrete to set and gain strength are significantly slowed. If the temperature drops too low, it can prevent the concrete from reaching its intended structural integrity, potentially leading to long-term durability issues. Proper temperature management is essential during the curing process to ensure the mix does not suffer from these negative impacts.1
