Many people will use mortar when building a house, there are two types of cement mortar and cement mixed mortar on the market, which sounds almost the same, so it is thought that these two kinds of almost a role. In fact, this idea is not right, today by the small series to introduce you to the difference between cement mortar and cement mixed mortar, cement mortar construction process, I hope you can correct the previous misunderstanding after reading.
What is the difference between cement mortar and cement mixed mortar? Cement mortar construction technology?
First, the difference between cement mortar and cement mixed mortar
Cement mortar by cement, fine aggregate and water, and according to the need to add lime, active admixtures or admixtures in the field of mortar, divided into cement mortar and cement mixed mortar. Usually said 1:3 cement mortar is to use 1 part of cement and 3 parts of sand, in fact, ignoring the composition of water, generally in about 0.6 ratio, that is, should become 1:3:0.6, the density of cement mortar is 2000Kg/m3. When cement mortar is used, some additives such as micro foaming agent and waterproof powder are often added to improve its workability and viscosity. Concrete is formed when stones are added to cement mortar in proportion. The label strength of cement mortar refers to a value in the overall distribution of compressive strength of 7.07CMX7.07CMX7.07CM cube specimen made and maintained by standard method at 28d age, measured by standard test method. No. 100 cement mortar means that its strength is 100Kg/cm2, all changed to MPa as a unit, 100 corresponds to M10.
Cement mixed mortar is generally made of cement, stone ash paste, sand mix, generally used for masonry above the ground. Due to the addition of stone ash paste, the workability of the mortar is improved, and the operation is more convenient, which is conducive to the improvement of masonry compactness and work efficiency. The identification of cement mixed mortar looks at the color, lime mortar is white, mixed mortar is medium gray, and cement mortar is darker. Although the early strength of lime mortar is low, the strength is not low after the air is hard in the air, and the nails are immovable. Mixed mortar also adds other materials (such as: stone plaster, mortar king), its masonry performance is better, commonly used in the wall "moisture-proof layer" above the brick masonry and wall coating used (as a wall coating kitchen, bathroom can not be used.
Second, the construction technology of cement mortar
The basic process of cement mortar plastering is to find rules, the four corners of the wall are flattened, the vertical line is lifted straight, the production of standard gray cake, punching bar, Yin and Yang Angle is squared, the internal wall plastering, the bottom is lower than the punching bar, the middle layer is flat punching bar, and the surface layer is decorated. Cement mortar plastering construction points must be made before plastering standard ash cake. Stamping is also an important link to ensure the quality of plastering, and is an important control sign when plastering a large area. The Angle of Yin and Yang is also an important process directly related to the quality of subsequent decoration projects. Strictly speaking, the composite ratio has a great relationship with the sand particle size, water content, the actual strength of cement and the construction level. Assumption: Cement 32.5 grade (actual strength 37.5), the use of medium sand, sand moisture content is 1.5%, construction level: general, preparation strength 8.71MPa. The mix ratio of cement mortar per cubic meter M7.5 is (weight ratio): cement: sand =1 5.51 Material dosage: cement :267Kg medium sand :1472kg As for water, roughly 40kg, which should be adjusted according to the actual situation on site.
The above small edition of the difference between cement mortar and cement mixed mortar, the introduction of the construction process of cement mortar for you to say here, I believe you already know that cement mortar and cement mixed mortar are different, there are still differences between them, so that when you need to use mortar in the future, you can choose their own according to their characteristics.
