EFFECTS OF MORTAR ADDITIVES 2.1 Portland cement mortar pore sealing In pore sealing one needs to use agglutinating products, water reducers which at the same time should not be washed away by water or do not have any negative effect on cement hydration.

砂浆添加剂的效果 2.1硅酸盐水泥砂浆孔隙密封孔隙密封一个需要使用凝集产品，对水减速的同时不应该被水冲走或不产生任何负面效果影响水泥水化。

With regards to the use of polymer cement concrete in hazardous waste landfill site, this dissertation studied the mechanical property and durability of cement mortar modified by acrylic ester copolymerizing emulsion systematically.

本论文针对聚合物水泥混凝土在有害废物填埋场中的应用，系统地研究了以丙烯酸酯共聚乳液改性水泥砂浆的力学性能和耐久性能，并。。。

Following is the factors ideating with the surface of old concrete in different way ( including brushing surface , chiseling surface , cleaving surface ), adherence agent ( including cement slurry , cement sand slurry , cement slurry with the u expansion agent ), the freeze - thaw circulation times and air - entraining .

主要考察了老混凝土表面不同处理方式(刷毛面，凿毛面，劈裂面)、界面粘结剂类型(水泥净浆，水泥砂浆， u型膨胀剂水泥浆)、冻融循环次数等对新老混凝土粘结面劈拉强度的影响，以及冻融作用下新混凝土加气对粘结面劈拉强度的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
