預(yù)拌砂漿在加工過(guò)程中需要進(jìn)行篩分和烘干，所以砂漿中的砂幾乎不含泥漿等雜質(zhì)，符合標(biāo)準(zhǔn)要求，可以保證測(cè)量的準(zhǔn)確性。并由廠家生產(chǎn)，用于建筑工程中的各種砂漿拌合料，是我國(guó)近年來(lái)開(kāi)發(fā)的一種新型建筑材料。
Pre-mixed mortar needs to be screened and dried in the process of processing, so the mortar contains almost no impurities such as mud, which meets the standard requirements and can ensure the accuracy of measurement. It is a new type of building material developed in recent years in China, which is produced by professional manufacturers and used in various kinds of mortar mixtures in construction projects.
還有一點(diǎn)很重要，拌和砂漿由拌和站事先提供拌和好(不加水)干粉提供工地，使用時(shí)加水拌和即可。質(zhì)量好，成本高。而抹灰砂漿通常分為普通抹灰和裝飾抹灰兩大類，根據(jù)抹灰砂漿功能的不同類型，抹灰砂漿可分為普通抹灰砂漿、裝飾抹灰砂漿和特殊抹灰砂漿。
Another important point is that the mixing mortar is provided by the mixing station in advance to mix well (without water) dry powder to provide the site, when used, it can be mixed with water. Good quality and high cost. The plastering mortar is usually divided into ordinary plastering and decorative plastering. According to the different types of plastering mortar function, plastering mortar can be divided into ordinary plastering mortar, decorative plastering mortar and special plastering mortar.
一般抹灰砂漿的強(qiáng)度要求不是很高，中等強(qiáng)度等級(jí)的水泥可以滿足要求。抹灰砂漿的強(qiáng)度不應(yīng)超過(guò)基材的兩個(gè)強(qiáng)度等級(jí)。貼面磚內(nèi)外墻，中層抹灰砂漿強(qiáng)度不低于M15，水泥抹灰砂漿優(yōu)先。
Generally, the strength requirement of plastering mortar is not very high, and the cement of medium strength grade can meet the requirement. The strength of plastering mortar should not exceed the two strength grades of the base material. The strength of plastering mortar in the middle layer is not less than M15, and the cement plastering mortar is preferred.
在施工過(guò)程中，采用預(yù)拌砂漿提高了砂漿的強(qiáng)度，給抹灰技術(shù)和抹灰基質(zhì)的界面處理帶來(lái)了一些新的變化。采用低強(qiáng)度砂漿可提高抹灰效率，減少抹灰層空鼓開(kāi)裂。
In the construction process, the use of ready-mixed mortar improves the strength of mortar, bringing some new changes to the plastering technology and the interface treatment of plastering matrix. Using low strength mortar can improve plastering efficiency and reduce hollow cracking of plastering layer.
由于相關(guān)標(biāo)準(zhǔn)對(duì)預(yù)拌砂漿的強(qiáng)度沒(méi)有質(zhì)量要求，現(xiàn)場(chǎng)施工時(shí)常要配制低強(qiáng)度抹灰砂漿，相當(dāng)數(shù)量的工程砂漿強(qiáng)度不能滿足工程的要求。由于砂漿抹灰層充滿粉料，一拉就會(huì)脫落，砂漿抹灰工程的質(zhì)量無(wú)法滿足裝飾要求。冬季砂漿強(qiáng)度增長(zhǎng)緩慢，這種情況尤為明顯，客戶投訴較多，現(xiàn)拌砂漿對(duì)砂漿強(qiáng)度已有規(guī)定。預(yù)拌砂漿的強(qiáng)度增加后,砂漿抹層的剛度增加,和砂漿的拉伸應(yīng)力抹一層一層抹接口治療增加,抹的治療質(zhì)量必須相應(yīng)改善,基礎(chǔ)表面和建設(shè)必須進(jìn)行嚴(yán)格按照抹建設(shè)法規(guī),以確保施工質(zhì)量。
Because there is no quality requirement for the strength of ready-mixed mortar in relevant standards, low-strength plastering mortar is often prepared in site construction, and a considerable amount of Engineering mortar strength can not meet the engineering requirements. Because the mortar plastering layer is full of powder, it will fall off when pulled, and the quality of mortar plastering engineering can not meet the decorative requirements. In winter, the strength of mortar increases slowly, which is particularly evident. There are many complaints from customers, and the strength of mortar has been regulated by ready-mixed mortar. When the strength of ready-mixed mortar increases, the stiffness of the mortar coating increases, and the treatment of the interface layer by layer with the tensile stress of the mortar increases. The treatment quality of the plastering must be improved accordingly. The foundation surface and construction must be strictly in accordance with the construction regulations to ensure the construction quality.
