Influence of steel plates on the compressive strength and pore structure of concrete

Abstract

Abstract To accurately predict the strength of concrete in a combined structure, this paper analyzed the effect of steel plates on the pore structure and strength of concrete. Two concrete strengths and eight steel plate thicknesses were used for the experimental specimens, and their pore structures and strengths were tested at 3, 7, and 28 days. It was found that the pore structure of concrete increased with the increase in steel plate thickness. Additionally, the strength of concrete decreased with the increase in steel plate thickness. Besides, an equation was proposed to predict the strength of concrete in specimens with steel plates in this research.
