✦ Synopsis

The aim of this study was to investigate the influence of temperature, alkali and cement set on the visco-etastic properties of chip mattresses made in cement and calcium hydroxide, respectively. Two temperatures were used, room temperature and 78 ~ believed to represent the limits of the range of temperatures experienced industrially in the manufacture of cement composites. Calcium hydroxide and cement were used to f~md the. effect of alkali and the effect of cement set. The temperature affected the visco-etastic properties by increasing the unrecovered strain, and aIkali also increased the unrecoverable straim The effect of heat and alkali increased when the two were used in combination. In cement chip composites,, the effect of cement set was the most dominant that the effect of beat and alkal~ could not be observed.
