Dry-mix mortar is a new type of building material, which is made of a mixture of materials such as cement, aggregate (sand, stone) and additives. Compared with traditional wet-mix mortar, dry-mix mortar has many advantages, such as easy storage, convenient transportation, fast hardening speed, strong cohesion, etc. Therefore, dry-mix mortar has been widely used in the construction industry.
The preparation of dry mix mortar is very simple, you only need to mix various raw materials together according to a certain ratio, and then add an appropriate amount of water and stir well. However, in order to prepare a high-quality dry-mix mortar, the following points need to be noted:
First of all, the quality of the raw materials is key. The quality of raw materials such as cement, sand, and stone must meet the relevant standards, and the choice of additives should also be based on the specific situation, and cannot be used at will.
Secondly, the ratio is an important part of the preparation of dry mix mortar. Different ratios will directly affect the performance of the mortar, so it needs to be selected according to the actual needs. At the same time, the ratio should also be adjusted according to the quality of the raw materials to ensure the stable performance of the mortar.
Thirdly, stirring is an important step in the preparation of dry mix mortar. When stirring, it is necessary to ensure that all kinds of raw materials are fully mixed and even, and there can be no particles or agglomeration. The mixing time should also be properly controlled, too long or too short will affect the performance of the mortar.
Finally, storage and transportation are also links that need attention. In the process of storage and transportation, dry-mix mortar needs to avoid dampness, rain and other adverse environmental impacts, so as not to affect its performance.
As a new type of building material, dry-mixed mortar has broad application prospects and development space. In the future, with the continuous progress of technology and the continuous expansion of application fields, dry mix mortar will play a more important role and contribution in the construction industry.
