Abstract This paper presents the flexural test results of 10 lithium slag reinforced concrete beams (120 × 200 × 1,100 mm3) subjected to the combined effect of loading and Thermal-Cold (TC) cycles. The parameters include the polypropylene (PP) fibers, number of TC cycles and level of flexural loading. The results show that the cracking load, ultimate load, maximum crack width and deflection improve significantly after 100 TC cycles and deteriorate slightly after 300 TC cycles. As the percentage of the peak moment, which is an experimental value, increases from 0.20 to 0.35, the deflection decreases, the cracking load increases, and there is no noticeable change in the ultimate load. Further, the addition of PP fibers to the concrete beams enhances both the cracking load and the ultimate load, reduces the maximum crack width, and improves the resistance to erosion.
