Mortar construction is a very important work in the construction industry. It involves the structure and appearance of buildings and has a vital impact on building quality and safety. This article will introduce in detail the relevant knowledge and skills of mortar construction, as well as common problems and solutions in mortar construction.

The basic concept of mortar construction

Mortar refers to a kind of bonding material mixed with cement, lime, sand, and other materials in a certain proportion. Mortar construction refers to the application of mortar on the walls, floors, and other surfaces of buildings to fill brick joints, repair walls, paste tiles, etc. It can not only beautify the appearance of the building but also improve the structural strength and durability of the building.

The technological process of mortar construction

Preparation of mortar: Mix cement, lime, and sand in a certain proportion, add the appropriate amount of water, and stir evenly.

Base treatment: Before construction, it is necessary to treat the base, clean up sundries, apply interface agent, etc., to ensure the adhesion and firmness of the mortar.

Mortar application: apply the prepared mortar on the surface of the base, and compact the mortar with a scraper, trowel, and other tools to ensure a close fit between the mortar and the base.

Smoothing: Before the mortar is completely dry, use a wooden board or trowel to smooth the surface of the mortar for subsequent construction.

Brushing treatment: After the mortar starts to dry, use a brushing tool to roughen the surface of the mortar to increase the roughness of the mortar surface and improve the adhesion between the mortar and subsequent materials.

Common problems and solutions in mortar construction

Mortar cracking: Mortar is prone to cracking during construction, which may be caused by the uneven base and insufficient cement dosage. The solution is to fully treat the base layer before the mortar is applied to enhance the flatness and firmness of the base layer.

Mortar falling off: Mortar falling off can be caused by insufficient adhesion between the mortar and the base layer, or by improper mortar preparation. The solution is to treat the base layer before construction to increase its surface roughness to increase the friction between the mortar and the base layer. At the same time, an appropriate amount of binder should be added to the mortar preparation to improve the adhesion of the mortar.

Mortar color difference: In the construction, the color of mortar may be uneven, which may be caused by improper proportion of cement, lime, and sand during mortar preparation, or humidity, temperature, and other factors during mortar construction. The solution is to strictly control the proportion of each material in the mortar preparation, and at the same time keep the environment stable during the construction process to avoid the influence of humidity and temperature changes on the color of the mortar.

Matters needing attention in mortar construction

• Strictly control the proportion of mortar to avoid improper proportions leading to a decline in the quality of mortar.
• Fully treat the base layer before construction to ensure that the base layer is flat, clean, and firm.
• During the construction process, pay attention to controlling the humidity and temperature of the construction environment to avoid affecting the construction quality of the mortar.
• After the construction is completed, timely maintenance should be carried out to avoid problems such as excessive drying and cracking of the mortar.

Mortar construction is a very important work in the construction industry, which has a vital impact on construction quality and safety. During the construction process, the quality of each link needs to be strictly controlled to ensure that the mortar construction quality meets the standard requirements. At the same time, it is also necessary to solve various problems in mortar construction in time to ensure construction quality and building safety.
