Embodiment Construction

[0036] Embodiment is referring to Fig. 1, Fig. 2, shown in Fig. 3, this permeable concrete pavement surface porosity and test block section porosity detection method, it is characterized in that the steps are as follows:

[0037] Step 1. Select a detection area on the hardened concrete surface 11. The detection area is composed of solid parts and pore parts. The above-mentioned hardened concrete surface is a concrete permeable road surface, a section of a concrete test block or a surface of a concrete component.

[0038] Step 2. Apply a layer of ink 12 evenly on the concrete in the detection area. You can also apply other pigments, paints or coatings. In order to prevent insufficient brushing or excessive ink brushing, paint all the solid parts of the concrete with ink In degrees, the ink-painted area of ​​the detection area is the size of an A4 paper. The tool of painting color juice can be flat head brush 14, sponge or cloth ball.

[0039] Step 3. Before the ink is dry, tak...

Abstract

A method for detecting porosity of pavement surface prepared by water penetration concrete includes brushing a layer of color juice on detection region of pavement surface, covering a white paper on brushed region before color juice is divided off, pressing balanced pressure on white paper fro mark-printing out print image being inputted into computer to carry out pixel binary treatment for calculating out area ratio of color print on complete white paper and utilizing a formula to calculate out porosity of concrete pavement surface based on said area ratio.

Description

(1) Technical field [0001] The invention relates to a method for detecting the compactness and porosity of concrete, in particular to a method for detecting the compactness and porosity of a permeable concrete pavement or a concrete test block. (2) Background technology [0002] The surface density and porosity of concrete are two technical parameters that restrict each other, and they are also two main technical indicators that determine the quality of concrete construction. The surface compactness ρ refers to the filling degree of solid substances on the surface of the material, and the surface porosity is the ratio of the surface pore area of ​​the material to the total area, and its calculation formula is γ=100%-ρ. The porosity and compactness of materials are interrelated properties. The surface porosity of materials can directly reflect the compactness of the material surface. The larger the surface porosity, the smaller the surface compactness. In the construction of...
