As there was a large amount of red clay distributed in Bijie, which is used as the foundation of building and roadbed. To study the improvement effect of cement content on the Bijie red-clay, the typical red clay in Bijie was firstly sampled and the basic physical property indexes were tested. Then, the samples with different cement ratio were made and the unconfined compressive strength test was carried out. The results indicate that the strength of cement red-clay was increasing with the cement ratio increasing, and the improved effect is obviously, but the variation curve is not linear. The peak strength appeared when the cement ratio is 10%, after that ratio, the strength was decreasing with the increase of cement ratio. The reason is that the incorporation with cement makes Bijie red-clay harden because of the hardening cement.
