结果表明，利用合成产品的无泌水水泥净浆流动度的保持性能可以定性判定合成产品在保持混凝土坍落度方面的能力。
The results show that the ability of the synthesis production to control the slump loss can be qualitatively determined through the ability to keep the fluidity of cement paste without bleeding.
并且由于其具有FDN缓释效果，还能有效延长水泥的净浆流动度，减少混凝土坍落度的经时损失。
Besides, it effectively maintains fluidity of cement paste and decreases concrete slump loss which is attributed to absorption effect of zeolite to FDN.
