Abstract
CA, CA2 and their mixes with and without alumina aggregate were allowed to hydrate below 25°C and in not less than 90% relative humidity. The various phases formed were determined by X-ray analysis. The data obtained showed that the hydration products of CA were C3AH6 and AH3 whereas CA2, CA—CA2 mixes gave higher percentage of CAH10 and AH3. Hydrated CA mixes with Al2O3 after firing gave CA2 and CA6, whereas CA—CA2 mixes gave CA6. The strength value of CA—CA2 mixes increased with increase in CA2 content whereas PCE value increased with increase in CA2 content.
