中文摘要：

Welan 口香糖广泛地由于它的好变厚和 rheological 性质在环境混合被使用。与它在分子的结构的强大的费用密度，在 welan 口香糖和另外的混合之间的竞争吸附在增加过程期间显著地发生了。那么控制 welan 口香糖的释放的率将能改进竞争吸附，当没有劣势到它同时变厚和可使用性时。延期的影响的调查在水泥臼的流动性和力量上释放了 welan 口香糖( DRWG )，为水泥浆糊，吸附数量和 clinker 的希腊语的第六个字母潜力的率和 rheological 性质放血单个矿物学的阶段，证明将在有 DRWG 的臼力量有更好的臼可使用性和某些改进。为有 DRWG 的臼，站为率放血是 0，并且有更少的 thixotropic，更少的吸附，和一个更低的希腊语的第六个字母潜力 clinker 的表面上的价值矿物学的阶段。

英文摘要：

Welan gum is widely applied in environmental admixtures due to its good thickening and rheological properties. With its powerful charge density in the molecular structure, the competitive adsorption between welan gum and other admixtures happened remarkably during the addition process. So controlling the releasing rate of welan gum will be able to improve the competitive adsorption, while having no disadvantages to its thickening and workability at the same time. The investigation of influences of the delay released welan gum（DRWG） on the fluidity and strength of cement mortar, bleeding rate and rheological properties of cement paste, adsorption amount and zeta potential of clinker single mineralogical phases, shows that there will be a better mortar workability and certain improvement in mortar strength with DRWG. For mortar with DRWG, the standing bleeding rate is 0, and there is less thixotropic, less adsorption, and a lower zeta potential value on the surface of clinker mineralogical phases.
