Optimized Design of Ultra-High Performance Concrete Incorporating Steel Slag Based on Multiple Response Approach

Abstract

Abstract: In order to achieve the composition optimization of eco-type UHPC and the improvement of the utilization rate of steel slag, using steel slag as auxiliary gelled material, the eco-type UHPC was prepared by D-optimal design method and establish the workability prediction model and the compressive strength prediction model to carry out multiple response analysis. With the help of the prediction model, the eco-type UHPC with low cement consumption and high steel slag utilization rate is designed to meet the requirements. The results show that the prediction model is reasonable and accurate. In the prediction model, superplasticizer and silica fume have a great influence on the workability, the interaction of cement, superplasticizer and steel slag have obvious influence on the workability and the addition of steel slag powder enhances the workability. The influences of silica fume and steel slag powder om compressive strength are significant, the interaction of cement and steel slag has little effect on compressive strength and the optimal value of compressive strength exists with the increase of steel slag powder. The optimal ratio of the eco-type UHPC realizes the substitution of steel slag for 30% (mass fraction) cement, and ensure the compressive strength above 130 MPa and the working performance above 260 mm.
