Specific implementation mode
The invention will be further described below.
The test method for measuring eco-concrete pH of the present invention, includes the following steps：
Step 1 makes the eco-concrete sample test block of two same volumes, measures its quality respectively：
Under lab, according to two eco-concrete sample test blocks of making are required, as shown in Figure 1, two ecological coagulations
The cylinder of the preferable cube for being made as length of side 100mm of earth sample test block or diameter 100mm, high 100mm, is being marked
Quasi- maintenance 7 days after, with dry towel wipe test block, so that its surface is not dripped, with two pieces of eco-concrete sample test blocks of balance pair into
Row is weighed, and is accurate to 1g, and record its data.
Step 2 determines that the quality of distilled water and undisturbed soil is added in two eco-concrete sample test blocks：
As shown in Figures 2 and 3, two eco-concrete sample test blocks are respectively put into A containers and B containers (A containers and
It is the bottom surface length of side 200m of B containers, high unlimited), the undisturbed soil and certain mass of certain mass are proportionally added in A containers
Distilled water, pays attention to plus distilled water will be uniformly distributed, and ensures the wetting of eco-concrete sample test block entirety as possible；Proportionally exist
The distilled water of certain mass is added in B containers, pays attention to ensureing the height that liquid level is higher than eco-concrete sample test block.
Preferably, the undisturbed soil quality being added in A containers is 18% of eco-concrete sample test block quality in the container,
The distillation water quality being added in A containers is the steaming being added in 2%, the B containers of eco-concrete sample test block quality in the container
Distilled water quality is 20% of eco-concrete sample test block quality in the container.
Step 3 determines the pH value of initial environment in A containers and B containers：
Behind 2 hours that addition eco-concrete sample test block is disposed, residing for eco-concrete sample test block
Environment carries out the measurement of pH value：The initial pH value that native environment in A containers is measured with soil acidity or alkalinity meter, to different location (desirable 6
The point of a different depth) carry out pH value measurement, take its average value, make a record；Water in container B is measured with portable pH meter
The initial pH value of environment, is stirred before testing, and the survey of pH value is carried out to different location (point that can use 6 different depths)
It is fixed, its average value is taken, is made a record.After A containers and B containers measure, it is sealed preservation, the evaporation of moisture is prevented, builds
The control of experimental situation temperature is discussed at 20 ± 2 DEG C.
Step 4 determines the pH value of environment in different larval instar A containers and B containers：
Eco-concrete sample test block by certain age (7 days, 14 days or 28 days can be set as certain age, can basis
Actual conditions set age), eco-concrete sample test block institute in A containers and B containers is measured using the method for step 3 respectively
Locate the pH value of environment, and makes a record.
Step 5 carries out eco-concrete pH value comprehensive according to the pH value for the initial environment surveyed and different larval instar pH value
Evaluation is closed, to judge to be suitble to the eco-concrete growing plants type.
According to the pH value for the initial environment surveyed and different larval instar pH value, show that eco-concrete is precipitated in certain age
Total alkali content and ecological environment alkali number actual evaluation is carried out for the engineering of eco-concrete application, is made according to this numerical value
It preferably meets ecological environment.
Although the function and the course of work of the present invention are described above in conjunction with attached drawing, the invention is not limited in
Above-mentioned concrete function and the course of work, the above mentioned embodiment is only schematical, rather than restrictive, ability
