USE OF CHINLE CLAY AND MODERATE HEAT FOR THE PRODUCTION OF SYNTHETIC AGGREGATES

A testing program was laid out to determine what conditions and factors affected the strength of the synthetic aggregate produced from Chinle Clay. The factors considered in the experimental program were: Temperature of sintering, Time of sintering, Moisture content, Clay content and wet density. The tests showed that the main factors affecting the strength were temperature and wet density. Moreover, the results show that while it is not possible to use moderate heats, i.e., temperatures ranging from 204 C to 650 C it is possible to produce a strong aggregate from Chinle Clay with a temperature of 1100 C.
