Test method for the mixture ratio of slurry in concrete.

Step 1: using the raw materials currently used, the concrete slurry with different mineral admixtures is obtained according to the concrete mix ratio and the concrete proportion of different mineral admixtures. The mix of concrete includes rubber, sand, stone, water and admixtures, including mineral admixture and cement.

Step 2: the pH value of concrete slurry with different mineral admixture ratios is measured, and the standard pH value database of concrete slurry in different mineral admixtures is obtained. The pH of concrete slurry was measured by pH meter.

Step 3: according to the actual production process of concrete slurry preset proportion of mineral admixtures, from the standard of concrete slurry pH value in the database to determine with the preset proportion corresponding mineral admixtures concrete standards of slurry pH value.

Step 4: measure the pH value of concrete slurry in actual production.

Step 5: will the concrete slurry pH value in the process of actual production and the standard of concrete slurry pH value, and test the actual production in the process of concrete dosage of mineral admixture is in line with the design value in advance.
