Changes in temperature in aggregates cause expansion and cracking in the mixture they belong to. Intense heat produces physical and chemical deterioration. It also dissolves the mineralogy of the aggregate, potentially generating new unwanted chemical compounds. Our equipment such as the multi-purpose climatic chamber (for all construction materials) will help you determine the resistance of aggregates to freezing and thawing. In this section, you will also find lab equipment that assess how aggregates affect the shrinkage of concrete due to drying.
