[0036] Examples are shown in Figure 1, Figure 2, and Figure 3. This method for detecting surface porosity of permeable concrete pavement and section porosity of test block 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 hardened concrete surface is a concrete permeable pavement, a section of a concrete test block or a surface of a concrete member.
[0038] Step 2. Apply a layer of ink 12 evenly on the concrete in the inspection area. You can also apply other pigments, paints or paints. In order to prevent insufficient painting or excessive ink painting, all concrete parts are painted with ink For degrees, the ink application area of the detection area is the size of A4 paper. The tool for applying the color juice can be a flat brush 14, a sponge or a cloth ball.
[0039] Step 3. Before the ink is dry, take a piece of white paper corre...
