Experimental Study of Pore Structure and Compressive Strength of Reinforced Concrete

Experimental research on how reinforcing bars affect the pore structure and compressive strength of concrete was studied in this work. The samples used in the tests were from concrete with 2 mix ratios and 9 reinforcement ratios. At three, seven, and twenty-eight days old, respectively, the concrete compressive strength and the structure of pores were examined. The pore structure of the concrete was discovered to alter as a result of the reinforcing bars. The size of the pore structure of concrete grew larger together with the reinforcement ratio. As the reinforcement ratio rose, the samples of reinforced concrete of the same age lost compressive strength. The formula for calculating the compressive strength of reinforced concrete samples was developed based on the known strength of plain concrete.
