Embodiment Construction

[0026] The present invention will be further described below.

[0027] The test method of measuring ecological concrete pH of the present invention may further comprise the steps:

[0028] Step 1, make two ecological concrete sample test blocks of the same volume, and measure their quality respectively:

[0029] In the laboratory, two ecological concrete sample test blocks are made according to the requirements, such as figure 1 As shown, the two ecological concrete sample test blocks can be preferably made into a cube with a side length of 100 mm, or a cylinder with a diameter of 100 mm and a height of 100 mm. After 7 days of standard maintenance, wipe the test block with a dry towel to prevent the surface from dripping , Weigh two ecological concrete sample test blocks with a balance, accurate to 1g, and record the data.

[0030] Step 2, determine the quality of adding distilled water and undisturbed soil to two ecological concrete sample test blocks:

[0031] Such as f...

Abstract

The invention discloses a test method for determining pH of ecological concrete. The method comprises the steps of making two ecological concrete sample blocks of the same volume, and respectively measuring the masses of the sample blocks; determining the mass of distilled water, needing to be added into the two ecological concrete sample blocks, and the mass of undisturbed soil of the two ecological concrete sample blocks; determining the pH values of the initial environments in containers A and B; determining the pH values of the environments in the containers A and B at different stages; evaluating the pH value of the ecological concrete according to the measured pH values of the initial environments and the pH values of the different stages. The test method provided by the invention comprehensively evaluates the pH value of the ecological concrete, thereby accurately reflecting the amount of alkali precipitated from the ecological concrete and the impact on the ecological environment, and providing technical guidance for the application of the ecological concrete.

Description

technical field [0001] The invention relates to the field of ecological concrete performance detection, in particular to a test method for measuring the pH of ecological concrete. Background technique [0002] Ecological concrete has become a social hot spot in recent years. Ecological concrete has begun to be applied in ecological slope protection, river courses and reservoir banks. Ecological concrete uses large-grained aggregates, and cement is used as an adhesive to glue the aggregates, making ecological concrete have a large number of large pores. Provides an environment for organisms. The application of ecological concrete in slope and revetment, ecological concrete not only increases the stability of revetment, but also provides conditions for the growth of plants in revetment. However, ecological concrete is a cement product. During use, there is alkali precipitation, which is not conducive to the needs of the ecological environment. For ecological concrete with dif...
