The hydration characteristics of calcium monoaluminate were studied using an effective water/aluminate ratio of 0.15 at 20 degrees or 80 degrees C, from a few minutes to two months. The material hydrated at 80 degrees C shows a large shrinkage while at the lower temperature a continuous expansion occurs. The product at 80 degrees C shows a much higher strength than that hydrated at 20 degrees C. The main initial hydration products are 2CaO, Al[2]O[3], 8H[2]O and alumina gel. Microcracks are developed in the products hydrated at 20 degrees C while at the higher temperature a very compact mass results. The data indicate that it is possible to obtain a durable high alumina cement by using a low water/cement ratio and hydrating at higher temper...
