Test on unconfined compressive strength of lightweight soil mixed with rubber chips of scrap tires
摘要
Abstract
In order to analyze the engineering characteristics of lightweight soil mixed with rubber chips of scrap tires (RST mixed soil), the unconfined compressive strength tests were carried out. Firstly, physical properties of the ingredient materials in RST mixed soil were studied. Then, the mixture ratio scheme and the preparation method of RST mixed soil samples were designed. Furthermore, influence laws of curing age, rubber-soil ratio, cement-soil ratio and water-soil ratio on the unconfined compressive strength of RST mixed soil samples were studied through unconfined compression tests. The results show that the unconfined compressive strength of RST mixed soil increases with the prolonging of curing age during the curing period of 28 d. When the cement-soil ratio is about 10%, the unconfined compressive strength of RST mixed soil is more sensitive to curing age. In addition, the unconfined compressive strength of RST mixed soil decreases with the increase of rubber-soil ratio, while it increases with the increase of cement-soil ratio. The optimal water-soil ratio of RST mixed soil corresponding to the unconfined compressive strength is about 25%.关键词
