Characteristics and application of cement retention agent
Cement tamping agent is a kind of high fluidity, easy to pour and dense material, especially suitable for the production of special-shaped component products. The role of cement sag agent: cement sag agent can keep the concrete slump A fast-loss additive. It can delay the hydration and condensation of cement and achieve the effect of maintaining slump. For high-efficiency water-reducing agents, it is often necessary to compound the components to be preserved, or to add them on site, otherwise the slump loss is fast and the construction is difficult. If the ambient temperature is high and the transport distance is long, a bulking agent or retarder should be used to achieve good results. The cement sag has the following advantages: enhanced effect: high water reduction (water reduction rate ≥ 30%), improved material durability, and significantly improved the strength of GRC at various ages. Easy to pour and compact, no segregation, good fluidity retention, so that the mortar is reduced or shaken. Improve dimensional stability and reduce the risk of component shrinkage. The surface is smooth and the defoaming function is excellent, so that the profiled member has a good appearance state, and the surface defects of the product are effectively reduced.
