Abstract

Abstract

In order to quickly and efficiently solve the stability problem of steel slag, this paper studied the effects of material factors (microbial concentration, urea concentration) and treatment methods (treatment time, treatment temperature) on the stability and compressive strength of steel slag modified by Bacillus Pasteuris. The impact of the above factors on the properties of microbe-modified steel slag was analyzed using X-ray diffraction analyzer, scanning electron microscope, and other testing methods. On this basis, the modified steel slag was applied to the road base, and the 7-day unconfined compressive strength and water-soaked expansion rate of the specimen were studied. The results showed that: 1) the volume stability of steel slag could be effectively improved by using Bacillus pasteuris. When the microbial content was 60% of the mass of steel slag, the urea concentration was 2 mol/L, the treatment temperature was (20±2) ℃, and the treatment time was 72 h, the treatment effect of microbial on steel slag was the best, and the content of f-CaO in steel slag was 2.98%, which met the requirements of the code. 2) using modified steel slag to prepare road base material, when the cement content was 6%, the 7-day unconfined compressive strength of the base course of Expressway and class Ⅰ highway, the base course of class Ⅱ and below highways, and the base-bottom course of class Ⅱ and below highways are 4.1 MPa, 4.6 MPa and 5.1 MPa, respectively. Compared with the specimens before modification, they were increased by 20.6%, 9.5%, and 8.5%, respectively. The water-soaked expansion rates were 1.77%, 1.84%, and 1.92%, respectively, which all met the requirements in the code of less than 2%.
