    High alumina cement (HAC) concrete undergoes with ageing a change in mineral constitution known as conversion which may be accompanied by a loss in strength. The amount by which this change in composition has gone, measured by the ratio of CaO·Al2O3·10 H2O to Al2O3·3 H2O is known as the degree of conversion (D c ). The faster the conversion goes the greater the loss in strength.
