Effects of Fillers on Compressive Strength of Sulfur Concrete

Abstract

Abstract: The optimized molding method was used to prepare the sulfur concrete samples by mixing fillers of cement, fly ash and slag, separately, and the effects of the type and content of fillers on the compressive strength of sulfur concrete were studied. The phase and micro morphology of filler and sulfur mixture were characterized by X-ray diffraction and scanning electron microscope. The results show that the cement filler has the best effect on the compressive performance of sulfur concrete, and the compressive strength is 87.2 MPa by adding cement filler with the same quality as sulfur (S/F=1.0). There is no chemical reaction between filler and sulfur, and the filler is physically bonded to the sulfur matrix.

Key words: sulfur concrete, filler, modified sulfur, compressive strength, micromorphology
