| Abstract: | Discussed the influence of compound additive which made by citric acid, phosphate and lignin sulphonate as main components on concrete properties.Observed the shape of hydrate product inside the concrete by SEM. Analysed effect mechanism of the compound additive to the concrete. The experiment result come out that the compound additive is in favor of the enhancement of the strength and is helpful to the improvement of the anti-permeability and the freeze resistance of the concrete. |
