water retaining admixture
解釋
保持水外加劑-
According to each ingredients ( water retaining admixture, polymer, inorganic mineral ) " effect to mortar ' s behaviors ( water relentivity, strength, contractility ) in exclusive mortar " s composite addition, the text defines each ingredient ' s quantity scope, then define the mix through cross experiment. we compared the aac exclusive mortar ' s behaviors such as water relentivity, compressive strength, binding strength, shrinkage, flexural strength and others to ordinary mortar ' s ones, it turn out to be that there is much improve in former ' s behaviors such as water relentivity, compressive strength, binding strength, shrinkage, flexural strength etc, it also shows that the aac exclusive mortar can improve the crack in aac brick walling to a certain degree
並根據專用砂漿中復合外加劑的各個組分（保水劑、聚合物、無機礦物等）對砂漿主要性能（保水性、強度、收縮性、抗彎性等）的影響來確定每個組分的摻量范圍，再通過正交實驗確定最佳配合比，然後就普通砂漿與專用砂漿的保水性、抗壓強度和粘結強度、收縮值、抗彎曲性能以及其它性能進行了對比，對比結果表明專用砂漿的保水性、抗壓強度和粘結強度、收縮值、抗彎曲性能以及其它性能較普通砂漿都有了很大的提高，說明加氣混凝土砌塊專用砂漿在一定程度上可以改善加氣混凝土砌塊墻體的開裂情況。
