First, the proportion of ingredients of mortar
The ingredient ratio of mortar is the key, and the general ingredient ratio is cement: lime: sand = 1:0.5:4. It should be noted that this is only a general proportion, and it needs to be adjusted according to the characteristics of the material and the construction requirements in the specific construction process. In addition, before mixing the mortar, it is necessary to prepare the required materials and tools in advance, such as mixers, mixing rods, buckets, etc.
Second, the mixing steps of mortar
1. Put sand, cement and lime into the mixer according to the proportion of ingredients, and carry out preliminary mixing with a mixing rod until the three materials are evenly mixed.
2. Pour an appropriate amount of water into the mixer and stir continuously until the mortar becomes smooth and uniform.
3. Add an appropriate amount of water and stir continuously until the mortar becomes a paste-like substance with a certain fluidity.
4. The mixed mortar needs to be kept agitated before the construction starts, and the mixing should not be stopped prematurely.
5. During construction, pour the mixed mortar into the place where it is needed, use a scraper or trowel to level it, and take necessary maintenance measures.
3. Precautions
1. The mixing of mortar requires an accurate grasp of the proportion and quality of the material.
2. When mixing mortar, keep the mixer, mixing rod and other tools clean, so as not to affect the quality of the mortar.
3. The mortar should be fully stirred during the mixing process to ensure that the mortar is mixed evenly.
4. The mixed mortar should be kept stirred before construction, and the stirring should not be stopped.
5. After the construction is completed, the tools should be cleaned and the construction area should be cleaned in time to avoid problems such as mortar blocking the water pipes.
