Experimental Study on Mechanical Properties of Iron Tailing Ore Pumice Concrete Porous Brick Masonry
In order to find a solution to the problem of iron tailings accumulation,based on material re-use,combined with the actual situation,this paper proposes to use iron tailing ore(ITO)and pum-ice stone respectively instead of part of fine and coarse aggregate to prepare the masonry block,and conduct the mechanical property test study on the masonry made of the masonry block.The failure process and failure form were analyzed by the tests of compressive,shear and flexural re-sistance along the joint and tooth joint.The results show that the masonry shows greater brittle-ness,the test values of compressive,shear and bending strength are all larger than the calculated values of the current specifications.Calculations using the current specification have certain safety reserves,but are inaccurate.In particular,the difference between shear and bending strength is too large,and t The main reason is the appearance of similar structural reinforcement pin key compo-nents.So regression analysis was performed using least squares on the experimental data of the masonry,establish the corresponding strength formula of average.
