Mortar is a commonly used material in the construction industry and is used for a variety of purposes, including caulking, plastering walls, and paving floors. The quality and performance of mortar directly affect the service life and safety of buildings, so the production technology of mortar is very important. This article will introduce the main content of mortar production technology, including raw material preparation, mortar mix design, mixing and processing, quality control, and other aspects.

Raw material preparation
The raw materials for mortar production mainly include cement, lime, sand, and various additives. Before mortar production, raw materials need to be prepared and processed. Specifically include the following aspects:
Cement and Lime: Cement and lime are the main binders for mortar. Screening, processing, and quality inspection are required before production to ensure that its quality meets the standard requirements.
Sand: Sand is the filling material in a mortar and is also the main volumetric component in mortar. Cleaning, screening, and sorting are required before production to ensure that the sand is of the required particle size and shape.
Additives: Additives include various additives, waterproofing agents, antifungal agents, water-reducing agents, etc. The use of additives should be selected and adjusted according to the actual use and requirements of the mortar.
Mortar mix ratio design
The mix ratio design of mortar is one of the key links in mortar production, and whether its design is reasonable or not directly affects the performance and quality of mortar. The mixed design of mortar should consider the following factors:
Raw material quality: Raw materials of different qualities require different mix ratios to achieve optimal results.
Engineering requirements: Different engineering requirements also require different mix ratios to meet different strength and durability requirements.
Mortar type: Different types of mortar require different mix ratios, such as ordinary mortar, putty mortar, waterproof mortar, etc.
Mixing and processing
The mixing and processing of mortar is also one of the key links in mortar production. The quality and technical level of mixing and processing directly affect the performance and quality of mortar. Specifically include the following aspects:
Mixing time: The mixing time of mortar should be controlled within a certain range, generally 2-3 minutes. If the mixing time is too long, the mortar will become too fluid, which is not conducive to construction.
Mixing intensity: The mixing intensity should be moderate, too strong will make the mortar too compact, which is not conducive to construction.
Stirring method: The stirring method should be selected according to the actual situation. The common stirring methods include mechanical stirring and manual stirring.
Processing method: The processing method of mortar includes manual plastering, mechanical plastering, spraying, and so on. The processing method should be selected according to the use requirements and construction conditions of the mortar.
Quality control in mortar production is an important link to ensure the quality of mortar. Quality control mainly includes the following aspects:
Quality control of raw materials: Quality control of raw materials is the first step in mortar production, and quality inspection and control should be carried out in strict accordance with national standards.
Mixing ratio control: The mixing ratio of mortar should be adjusted according to the actual situation, and a corresponding quality control plan should be formulated.
Processing control: processing control includes control of mixing, processing, stirring, etc., which should be adjusted according to the actual situation of the mortar.
Inspection control: Regular quality inspection should be carried out during the mortar production process to ensure that the performance and quality of the mortar meet the requirements.
In short, mortar production technology is a highly comprehensive subject, which needs to master certain knowledge of chemistry, physics, materials science, and construction technology. In the production process, the operation should be strictly by the standard requirements to ensure that the performance and quality of the mortar meet the requirements.
