With the coming of winter, exterior wall insulation projects have become the focus of many building owners. In exterior wall insulation, mortar is a commonly used insulation material, and it is crucial to choose the right mortar. The integrated insulation and decoration manufacturer will discuss the types, characteristics and selection principles of mortar.

Mortar is a building material mixed with cement, sand and water. It is a commonly used insulation material in exterior wall insulation projects. According to different raw materials, mortar can be divided into cement mortar, lime mortar and concrete mortar.

First, cement mortar is a mortar made of cement as the main raw material, adding an appropriate amount of sand and water. Cement mortar has the characteristics of high strength and good durability. It is suitable for parts that need to bear a certain load in exterior wall insulation projects, such as exterior wall bodies, foundations, etc. Its construction is simple and convenient, and the cost is low. It is a commonly used mortar in exterior wall insulation projects.

Secondly, lime mortar is a mortar made of lime as the main raw material, adding an appropriate amount of sand and water. Lime mortar has the characteristics of good water absorption and strong air permeability, which can effectively prevent moisture and mold from forming in the external wall insulation layer and keep the wall dry. Therefore, lime mortar is suitable for parts that need to have certain air permeability and heat preservation in external wall insulation projects, such as external wall bodies, doors and windows, etc.

Then, concrete mortar is a kind of mortar made of cement, sand and aggregate as the main raw materials, and an appropriate amount of water is added. Concrete mortar has the characteristics of high strength and good frost resistance, and is suitable for parts that need durability and frost resistance in external wall insulation projects, such as external wall corners, beams and columns, etc. Due to the difficulty of concrete mortar construction and the long construction period, it is generally not suitable for ordinary wall insulation in external wall insulation projects.

When choosing external wall insulation mortar, it is necessary to comprehensively consider its strength, durability, air permeability and construction difficulty according to the actual situation. For parts that need to bear a certain load, cement mortar can be selected; for parts that need to have certain air permeability and heat preservation, lime mortar can be selected; for parts that need durability and frost resistance, concrete mortar can be selected. In addition, it is also necessary to select according to the specific requirements and budget of the exterior wall insulation project to ensure that the appropriate mortar material is selected.

In general, the selection of exterior wall insulation mortar is a crucial part of the exterior wall insulation project. Only by selecting suitable mortar materials can the effect and quality of the exterior wall insulation project be ensured. Therefore, when carrying out exterior wall insulation projects, it is necessary to carefully select appropriate mortar materials to ensure the smooth progress of the project and the achievement of the display effect.
