Ice Concrete
The process of hydration of a concrete mix is heat liberating whereby any increase in the temperature of the concrete accelerates the rate of generation of heat. Concrete, in itself, is a bad conductor of heat therefore the evolution of heat due to the process of hydration occurs much faster than the rate at which it dissipates. These high temperatures developed have a number of effects some of which might even hamper the performance of the concrete in the long run. Ice concrete helps to alleviate this problem.
ADVANTAGES
• Thermal tensile cracks which might occur due to a temperature difference in the core and surface of the concrete, are mitigated by using Ice Concrete
• Enables early setting and stiffening of the concrete
• Instances of plastic shrinkage cracks greatly reduced
• Formation of Delayed Ettringite is successfully prevented
• The need to immediately cure concrete is also greatly reduced
• Later age of the concrete shows a continuous gain in strength
APPLICATION
• Deep Beams and Mass raft foundations
• Bridge piers and foundations
• Large walls used for retaining purposes
