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.水泥砂浆抹灰的根本工艺。 找规矩→,对墙体四角停止规方→横线找平，竖线吊直→制造规范灰饼、冲筋→阴阳角找方→内墙抹灰→底层低于冲筋→中层垫平冲筋→面层装修

　　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.水泥砂浆抹灰施工要点 抹灰前必需制造好规范灰饼。

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

　　3.冲筋也是保证抹灰质量的重要环节,是大面积抹灰时重要的控制标志。

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

　　4.阴阳角找方也是直接关系到后续装修工程质量的重要工序。

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

　　合比严厉地说，与运用的砂粒径、含水率、水泥的实践强度及施工程度有很大的关系。假定：水泥32.5级（实践强度37.5），运用的是中砂，砂子的含水率是1.5% ，施工程度：普通，配制强度8.71MPa.每立方米M7.5水泥砂浆的配合比是（重量比）：水泥：砂=1 5.51资料用量：水泥：267Kg 中砂：1472kg至于水，大致在40kg左右，这要依据现场的实践状况调整。

　　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.
