In recent years, polymer cement mortars using polymer dispersions have been widely used as finishing and repairing materials in the construction industry, because of their excellent properties compared with plain cement mortar. In particular, polymer cement mortar’s superior adhesion to that with plain cement mortar and concrete has attracted a great deal of attention from researchers, who have developed a number of unique applications for improving adhesion. The adhesion behavior between polymer cement mortar and substrate at the interface is known to be important for the improvement of adhesion of polymer cement mortar as a repair and reinforcement materials. This research was experimented on the mix designs and curing methods that affect the behavior of these interfaces. I want to present not only optimum mix design but also optimum curing condition of polymer cement so that construction workers will be able to use it properly as special material related to RC structure on site. The purpose of this study is to evaluate the effect of curing conditions on the adhesion in tension of polymer cement mortar to cement concrete substrate compared, with plain cement mortar. Polymer cement mortars using three polymer dispersions with various polymer-cement ratios are prepared and tested for the adhesion in tension of specimens subjected to four curing conditions: standard, dry, water, and under high temperature. The test results show that the adhesion in tension of polymer cement mortars increases with increasing polymer-cement ratio, irrespective of the polymer type and curing conditions, and it is the highest under standard curing. The polymer cement mortars have high adhesion in tension in the order ethylene–vinyl acetate (EVA) > styrene-butadiene rubber (SBR) > styrene-vinyl acrylic ester (SAE). The failure modes of specimens under conditions I and II and at high P/C of 15–20%, which showed high adhesion in tension, revealed relatively high S ratios, indicating cohesion failure of the base concrete. It is apparent from this study that the adhesion in tension of polymer cement mortars is considerably influenced by the curing condition, polymer-cement ratio, and type of polymer.

近年来，与普通水泥砂浆相比，使用聚合物分散体的聚合物水泥砂浆由于其优异的性能而被广泛用作建筑行业的饰面和修补材料。特别是，聚合物水泥砂浆比普通水泥砂浆和混凝土具有更好的附着力，引起了研究人员的极大关注，研究人员开发了许多独特的应用来改善附着力。已知聚合物水泥砂浆和界面之间的基材之间的粘附行为对于改善作为修补和增强材料的聚合物水泥砂浆的粘附是重要的。这项研究是在影响这些界面行为的混合料设计和固化方法上进行的。我不仅要介绍最佳的混合料设计，还要介绍聚合物水泥的最佳养护条件，以便建筑工人能够将其适当地用作与RC结构相关的特殊材料。这项研究的目的是评估与普通水泥砂浆相比，养护条件对聚合物水泥砂浆对水泥混凝土基材的拉伸粘合力的影响。制备了使用三种具有不同聚合物-水泥比率的聚合物分散体的聚合物水泥砂浆，并测试了在四种固化条件下（标准，干燥，水和高温）下样品的拉伸粘合力。测试结果表明，聚合物水泥砂浆的拉伸粘合力随聚合物-水泥比的增加而增加，而与聚合物类型和固化条件无关，在标准固化下是最高的。聚合物水泥砂浆具有高的拉伸粘合力，依次为乙烯-乙酸乙烯酯（EVA）>苯乙烯-丁二烯橡胶（SBR）>苯乙烯-乙烯基丙烯酸酯（SAE）。在I和II条件下以及在高P / C为15–20％时，试样的破坏模式显示出高的拉伸附着力，相对较高的S比，表明基础混凝土的内聚破坏。从这项研究中可以明显看出，聚合物水泥砂浆的拉伸粘合力在很大程度上受固化条件，聚合物-水泥比和聚合物类型的影响。在I和II条件下以及在高P / C为15–20％时，试样的破坏模式显示出高的拉伸附着力，相对较高的S比，表明基础混凝土的内聚破坏。从这项研究中可以明显看出，聚合物水泥砂浆的拉伸粘合力在很大程度上受固化条件，聚合物-水泥比和聚合物类型的影响。在I和II条件下以及在高P / C为15–20％时，试样的破坏模式显示出高的拉伸附着力，相对较高的S比，表明基础混凝土的内聚破坏。从这项研究中可以明显看出，聚合物水泥砂浆的拉伸粘合力在很大程度上受固化条件，聚合物-水泥比和聚合物类型的影响。
