Dry silt mortar is a kind of granular or powdery material, which is composed of aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) which are disposed of by dry screening and stops mixing physically in a certain proportion and is transported to the construction site in bags or bulk, and can be directly used after mixing with water. Also known as dry mortar powder, dry mortar, dry powder, some building adhesives also belong to this category. Dry mortar plays the role of bonding, padding, protection and decoration by thin layer in the construction industry. It is widely used in construction and decoration engineering.

　　1.水泥砂漿抹灰的根本工藝。 找規(guī)矩→,對墻體四角停止規(guī)方→橫線找平，豎線吊直→制造規(guī)范灰餅、沖筋→陰陽角找方→內(nèi)墻抹灰→底層低于沖筋→中層墊平?jīng)_筋→面層裝修

　　1. The basic technology of cement mortar plastering. Find the rules stop the rules at the four corners of the wall leveling the horizontal lines, hanging the vertical lines making standard gray cake, punching bar square of Yin and Yang angle plastering the inner wall plastering bar at the bottom flat punching bar at the middle cushion surface decoration.

　　2.水泥砂漿抹灰施工要點(diǎn) 抹灰前必需制造好規(guī)范灰餅。

　　2. The key points of cement mortar plastering construction must make standard gray cake well before plastering.

　　3.沖筋也是保證抹灰質(zhì)量的重要環(huán)節(jié),是大面積抹灰時重要的控制標(biāo)志。

　　3. Ribbon is also an important link to ensure plastering quality and an important control mark for large area plastering.

　　4.陰陽角找方也是直接關(guān)系到后續(xù)裝修工程質(zhì)量的重要工序。

　　4. Yinyang angle is also an important process directly related to the quality of the follow-up decoration project.

　　合比嚴(yán)厲地說，與運(yùn)用的砂粒徑、含水率、水泥的實(shí)踐強(qiáng)度及施工程度有很大的關(guān)系。假定：水泥32.5級（實(shí)踐強(qiáng)度37.5），運(yùn)用的是中砂，砂子的含水率是1.5% ，施工程度：普通，配制強(qiáng)度8.71MPa.每立方米M7.5水泥砂漿的配合比是（重量比）：水泥：砂=1 5.51資料用量：水泥：267Kg 中砂：1472kg至于水，大致在40kg左右，這要依據(jù)現(xiàn)場的實(shí)踐狀況調(diào)整。

　　Strictly speaking, it is closely related to the size of sand, water content, practical strength of cement and construction degree. Assumption: cement grade 32.5 (practical strength 37.5), using medium sand, water content of sand is 1.5%, construction degree: ordinary, preparation strength 8.71 MPa. Mix ratio of M7.5 cement mortar per cubic meter is (weight ratio): cement: sand = 15.51 data consumption: cement: 267 kg medium sand: 1472 kg water, roughly 40 kg, which should be adjusted according to the actual situation of the site.
