Plaster mortar is a kind of mortar to protect our buildings. It has the characteristics of water retention. What role does water retention play?

　　如果砂漿保水性太好，會帶來什么問題呢？主要體現在兩個方面。

　　If the water retention of mortar is too good, what problems will it bring? It is mainly reflected in two aspects.

　　首先，跟墻體接觸的表層水分被基層吸收，而中間層由于保水性太好，水分不容易轉移，就會 導致兩部分的實際水灰比有著較大的差異，包括砂漿的抗壓程度、粘接強度、凝結時間、收縮程度的發展進程也不一致，從而埋下了質量隱患。

　　Firstly, the water in the surface layer contacted with the wall is absorbed by the base layer, and the water in the middle layer is not easy to transfer because of its good water retention, which will lead to a great difference in the actual water-cement ratio of the two parts, including the compressive strength, bonding strength, setting time and shrinkage degree of the mortar.

　　另外，一般保水性太好的抹灰砂漿會使砂漿的凝結時間過長，從而影響整面墻體的強度發展趨勢。同時由于保水性太好導致表層砂漿與內部砂漿凝結出現較大時間差，出現表干內濕的結皮現象，影響外觀和施工進度。

　　In addition, plastering mortar with good water retention will cause the setting time of mortar to be too long, thus affecting the strength development trend of the whole wall. At the same time, because of the good water retention, there is a large time difference between the surface mortar and the internal mortar, and the crust phenomenon of surface drying and internal wetting occurs, which affects the appearance and construction progress.

　　預拌砂漿一聽肯定是覺得是提前拌好的意思，實際上在施工上確實是提前拌好的，這樣可以極大的改善施工環境，沒有那么大的塵土，提高工程質量，下面我就為大家講解。

　　Ready-mixed mortar must be thought to be premixed. In fact, it is premixed in construction. This can greatly improve the construction environment, not so much dust, and improve the quality of the project. I will explain below.

　　它不是簡單的從現場移到工廠生產，它是高質量的砂漿，推廣它是建筑施工技術進步的一項重要技術經濟措施，是保證建筑工程質量、提高建筑施工現代化水平、促進文明施工的項重要技術手段。

　　It is not simply moved from the site to the factory production, it is high-quality mortar, promotion is an important technical and economic measure for the progress of construction technology, is an important technical means to ensure the quality of construction projects, improve the modernization level of construction, and promote civilized construction.

　　另外原料可以使用建筑垃圾、煤矸石、鋼渣等工業固體廢棄物制造成的人工機制砂代替天然砂，可節約天然資源，且對產品品質無不良影響，還可消納粉煤灰等工業廢棄物，這樣既可以利廢，又可以減少環境破壞，達到節能減排的目的。

　　In addition, the raw materials can use artificial machine-made sand made from industrial solid waste such as construction waste, coal gangue and steel slag instead of natural sand, which can save natural resources and have no adverse effect on product quality, and can also absorb industrial waste such as fly ash, which can not only benefit waste, but also reduce environmental damage and achieve the purpose of energy saving and emission reduction.

　　隨著全國開始掀起了環保風，環保在位，越來越多的施工單位開始采購這種預拌砂漿。

　　With the national environmental protection wind, environmental protection in the first place, more and more construction units began to purchase this ready-mixed mortar.
