The main indicators for measuring the water retention performance of Water Retaining Agent For Ready-Mixed Mortar are water retention rate, water bleeding rate and stratification. Water retention rate refers to the ratio of water that the water retaining agent can retain to the total water within a certain period of time. The higher the water retention rate, the better the water retention performance of the water retaining agent. Water bleeding rate refers to the ratio of water exuded from the mortar to the total water. The lower the water bleeding rate, the more effective the water retaining agent can be in inhibiting the water secretion from the mortar. The stratification reflects the uniformity of the upper and lower layers of the mortar after standing for a period of time. The smaller the stratification, the more stable the mortar can be and the less likely it is to stratify.
In order to accurately measure the water retention performance of Water Retaining Agent For Ready-Mixed Mortar, the following test methods can be used. First, prepare the premixed mortar according to a certain mix ratio and add the water retaining agent. Then, put the mortar into a specific container and test it under specified conditions. For example, the filter paper method can be used to determine the water retention rate. The mortar is placed on the filter paper, and the water retention rate is calculated by measuring the water absorbed by the filter paper. For the test of water seepage rate, the mortar can be placed in a container, and after standing for a period of time, the volume of water exuded can be measured. The test of stratification is to put the mortar into the stratification cylinder, and after standing for a period of time, the height difference between the upper and lower layers is measured.
In summary, the water retention performance of Water Retaining Agent For Ready-Mixed Mortar can be measured by indicators such as water retention rate, water seepage rate and stratification. In practical applications, water retaining agents with appropriate water retention performance should be selected according to specific engineering requirements and construction conditions. At the same time, through scientific testing methods, the water retention performance of water retaining agents can be accurately evaluated, providing a strong basis for the quality control of premixed mortar. Only by selecting a water retaining agent with excellent performance and reasonably controlling its usage can the premixed mortar be ensured to have good construction performance and quality, providing a guarantee for the smooth progress of the construction project.
