basalt anticorrosive flower box
The main conclusions are as follows:
(1) Using the mixed preparation process, the dispersion effect of basalt fiber in the permeable concrete is the best, the compressive strength of the permeable concrete is significantly increased, and the effective porosity and water permeability coefficient decrease the least.
(2) Basalt fiber The incorporation of the permeable concrete has the effect of reducing the effective porosity and water permeability coefficient of the permeable concrete, and enhancing the compressive strength and flexural strength. When the fiber length is 12 mm and the volumetric content is 0.1%, the compressive strength of the permeable concrete And the flexural strength is the largest, respectively 27.4 MPa and 4.07 MPa. Based on the experimental data of basalt fiber permeable concrete, the regression equations of different basalt fiber lengths and basalt fiber content on the performance of permeable concrete are obtained by fitting.
(3) When basalt -When the total volume of polypropylene fiber is 0.1%, the polypropylene fiber will replace the basalt fiber in the same volume at a certain mixing ratio to enhance the effective porosity, water permeability, compressive strength and flexural strength of permeable concrete.
