Synthesis method of high-performance environment-friendly concrete admixture
The invention discloses a synthetic method of a high-performance environment-friendly concrete admixture. The high-performance environment-friendly concrete admixture is prepared from a modified polycarboxylate superplasticizer, a retarder, an expanding agent, an anti-foaming agent, an air entraining agent and polymer fibers. The high-performance environment-friendly concrete admixture prepared by the invention can effectively reduce the content of pores in concrete, improves the compactness and compactness of the concrete by reducing the problem of introducing bubbles, so that the strength and durability of the concrete are improved, and secondly, the high-performance environment-friendly concrete admixture can significantly reduce the mixing water demand of the concrete and reduce the production cost of the concrete. Meanwhile, the working performance of the concrete is kept, so that the water cement ratio is reduced, the overall strength and durability of the concrete can be improved, in addition, through detection of appearance quality indexes such as bubble density and voids and pitted surfaces, the surface quality of the concrete after the admixture is used is smoother, surface defects are reduced, and the service life of the concrete is prolonged. And the appearance quality of the concrete is obviously improved.
一种高性能环保型混凝土外加剂合成方法，其通过改性聚羧酸减水剂、缓凝剂、膨胀剂、抗泡剂、引气剂、聚合物纤维为原料制备而成；本发明制备而成的高性能环保型混凝土外加剂能有效减少混凝土中的气孔含量，通过减少引入气泡的问题，改善了混凝土的致密性和密实度，从而提高了混凝土的强度和耐久性，其次，它能够显著降低混凝土的拌合水需求，同时保持混凝土的工作性能，这不仅有利于减少水灰比，还能够提高混凝土的整体强度和耐久性，另外，通过对气泡密集程度、蜂窝麻面等外观质量指标的检测，可以看出使用该外加剂后混凝土的表面质量更加平滑，减少了表面缺陷的出现，使混凝土的外观质量得到了显著改善。
