  • characteristics of dry shrinkage and temperature shrinkage of cement Stabilized Steel slag
    Construction and Building Materials, 2017
    Co-Authors: Wei Li, Lei Lang, Zhihao Wang, Fanggang Zhang
    Abstract:

    Abstract The objective of the present study was to investigate the characteristics of dry shrinkage and temperature shrinkage of cement-Stabilized Steel slag (CSS). The Steel slag was intended to be utilized to replace the macadam in cement-Stabilized base course to reduce dry shrinkage and temperature shrinkage of semi-rigid base materials. Dry shrinkage and temperature shrinkage tests were performed to analyze the water loss rate, dry shrinkage strain, dry shrinkage coefficient and temperature shrinkage strain of CSS and cement-Stabilized macadam (CSM) as functions of time, cement content and gradation types of the material. The water loss rate of CSS increased with the rise in time, and then tended to be flat on about 10th days. The hygroscopicity of coarse gradation CSS was larger than those of intermediate gradation and fine gradation CSS. With the same gradation, the more the cement content was, the greater the water loss rate was. It was suggested that the cement content of CSS should not be more than 4%, which can obviously reduce the dry shrinkage strain. Compared with CSM, CSS with rational adjustment of gradation owned a smaller dry shrinkage strain and would not produce a larger temperature shrinkage strain. It is feasible to replace the base macadam with waste Steel slag, which is beneficial to improve the characteristics of dry shrinkage and temperature shrinkage of semi-rigid base material and utilization of waste Steel slag. This paper aims to provide a solid theoretical foundation to popularize the wide utilization of CSS in engineering applications.

  • Research on Road Base Material with Inorganic Binder Stabilized Steel Slag Sand
    2007
    Co-Authors: Li Jing-hui
    Abstract:

    The road base material which is made of the inorganic binder Stabilized Steel slag sand is a new type road base material.The unconfined compressive strength is used to be the evaluation index,the strength performances of three kinds of this road base materials,such as the lime-flyash Stabilized Steel slag sand,the fly ash Stabilized slag sand,the cement fly ash Stabilized slag sand,are studied in this paper. The optional mix proportion is also suggested.The inorganic binder Stabilized Steel slag sand is contrasted with traditional road base materials,and it shows the better strength performance,economy function advantage and the vast application.
