| 摘要： | The prime objective of this research is to investigate the effect of variation of sand and cement content on the porous concrete properties. Four aggregate gradations are selected by varying the percentage of sand (by volume) in total aggregate. Eleven types of mixes are used by varying the cement content for these four aggregate gradations. Dry unit weight, porosity, compressive strength, flexural strength, coefficient of permeability, clogging and abrasion resistance of the porous concrete are tested. The relationships among the engineering properties of the porous concrete are also discussed. With the increase of sand and cement content in porous concrete mixes the compressive strength, flexural strength and dry unit weight increases where as the porosity and coefficient of permeability decreases. The study indicates that clogging of porous concrete mixes resulted in the reduction of permeability. Abrasion values obtained from the tests are less than the specified values for heavy duty floor tiles. |
