Analysis of the Effect of Substitution Rate on the Mechanical Properties of Recycled Concrete Hollow Block
In this paper, to study the compressive and flexural properties of recycled concrete hollow blocks, the quality substitution rate of recycled fine aggregates is taken as a variable parameter, and four kinds of substitution rates are designed, which are 0%, 30%, 60%, and 100%. At the same time, one k...

| description | In this paper, to study the compressive and flexural properties of recycled concrete hollow blocks, the quality substitution rate of recycled fine aggregates is taken as a variable parameter, and four kinds of substitution rates are designed, which are 0%, 30%, 60%, and 100%. At the same time, one kind of recycled coarse and fine aggregates is designed, and the quality substitution rate is 100%. 110 specimens of MU10 and MU7.5 strength grades are tested for compressive and flexural strength. The failure process and morphology of the specimens are observed to obtain compressive and flexural strength. Based on the test data, the relationship between compressive and flexural strength of recycled fine aggregates with different replacement ratios is analyzed in detail. The main findings are that experiment results show the compressive and flexural strength decrease with the increase of substitution rate of recycled fine aggregates under the same other conditions. The work of the paper is a new reform for the source of raw materials for wall materials, and it is a new way for the reuse of concrete garbage and has important environmental protection significance and engineering practical significance for building energy saving. |
