为摸索微沫剂掺量和水泥用量使微沫砂浆强度发生变化的规律,我们做了一些工作。通过试验和实际应用,有以下几点认识: (1)微沫剂砂浆的和易性与拌合功能密切相关。 (2)在机械拌合条件下,材料和给定的和易性指标确定后,微沫剂按水泥用量万分比计的掺量随水泥用量的增加而减少,基本上与砂浆单位体积发生关系。 (3)对于砌筑砂浆,若保水性指标按施工操作容许的和易性取一定值,从而确定微沫剂掺量
In order to explore the rule that the strength of microfoam mortar changes with the amount of micro-foam agent and the amount of cement, we did some work. Through the test and practical application, there are the following points: (1) The workability of the micro-foam mortar is closely related to the mixing function. (2) Under the mechanical mixing conditions, after the determination of the material and the given workability index, the content of the micro-foam in terms of the cement ratio is reduced with the increase of the amount of cement, which basically relates to the unit volume of the mortar. . (3) For masonry mortar, if the water retention index is taken as a certain value according to the workability of the construction operation, the amount of micro-foam is determined.
