| Summary: | 碩士 === 逢甲大學 === 水利工程所 === 95 === In recent years environmental protection consciousness gradually took, also the traditional concrete had its shortcoming, namely of the porosity and the water permeability was bad, did not conform to requirement the ecology material, therefore this research was take the traditional concrete material as the research foundation, developed the water-permeable concrete by this foundation to become the new ecology material, provided application of reference the environment landscape and the project.
Therefore, this research through a series of experiments and the analysis, including bone material basic nature experiment, multi- holes concrete basic project nature experiment, allocated proportion of design the multi- holes concrete and hangs flows the experiment and so on five items, and obtains the preliminary achievement.
1. Best water-cement ratio pushes estimates by way of hangs flows the experiment to discover best water-cement ratio, the bone material particle size scope of in the 37.5~50mm, by way of hangs flows the experiment to be best water-cement ratio is 0.32~0.36, indicated the chassis comparatively not infiltrates the thick liquid situation.
2. Scope of water percolation of coefficient the water percolation coefficient this experiment is 4~22 cm/sec, expressed the multi- holes concrete has the high water percolation ability.
3. the porosity when water-cement ratio the value increases, the porosity value reduction.
4. The cleavage strength knew by the experiment, tensile strength of range multi- holes concrete, therefore cannot treat as the main structure to have auxiliary by other structure combinations, can display characteristic of the multi- holes concrete.
5. Of the compressive strength thick liquid bone compared to is enhances the multi- holes concrete intensity the primary factor, in order to achieve request the project, still must consider plants idea of the fresh project and the ecological engineering, therefore must conform to the porosity and correlation of requirement the water percolation coefficient.
