Deformation behavior of cement treated demolition waste with recycled masonry and concrete subjected to drying and temperature change
Abstract Cement treated materials are widely used as road bases in pavements. Shrinkage of these materials due to moisture and temperature changes is a critical issue for determining shrinkage cracking in pavements. This paper presents the influence of four mixture variables (masonry content, cement content, water content and degree of compaction) on drying shrinkage and coefficient of thermal expansion (CTE) of cement treated demolition waste with recycled masonry and concrete (CTMiGr). The experimental results showed that the masonry content was the dominating factor affecting dry shrinkage and CTE of CTMiGr. Increasing the masonry content can not only lead to an obvious decrease of dry shrinkage of CTMiGr, but also a low CTE level. Dry shrinkage of CTMiGr increased as the increase of cement content as well as degree of compaction and water content. The CTE of CTMiGr was between 7.58 × 10−6/°C and 10.22 × 10−6/°C, which was mainly determined by the masonry and cement content.
