My family has a house. What if the concrete smashed in the yard falls off and turns into sand?

The concrete on the floor of my yard was polished and peeled off. According to the actual situation, if the concrete floor is used for maintenance, it is easier to sand. A few years ago, the courtyard of our house was paved with concrete, and the construction method was traditional. The quality of sand, cement mortar, stone and water is unqualified, or the material ratio is wrong. The cement floor paved in the yard is easy to sand, crack and peel. Cement mortar requires high quality of concrete in the site, and P.042.5 composite portland cement mortar can be used.

Try to use medium sand for concrete construction, because medium sand is clean and contains no soil, and melon seeds are not used for stone. The melon seeds are too small and the compression effect is average. Choose stone with moderate size, and the ratio of several materials is normal, then the concrete construction effect in the yard is better. One of the materials has quality problems, and the cement floor in the yard is easy to sand. For example, it is thinner than sand and contains soil, the material ratio is normal, and the concrete made in the yard is not strong.

According to the concrete peeling and sand removal area of the yard, the following solutions will be carried out. The concrete floor has quality problems, and the relative consequences are basically serious. Because there is no better maintenance method, and maintenance can not fundamentally solve the problem. In this case, the area of peeling and sanding is small, so use a cutting machine to cut off the ground with half the thickness of concrete, clean up the cut muck and re-hit the concrete ground. You can add more high-grade cement mortar when mixing materials.

If the cement floor in the yard is sanded and peeled in a large area, the repair in a small area may not solve the problem, so the cement floor can only be made again. The yard area is relatively large, so it is recommended to use the concrete mortar mixed in the mixing station to hit the concrete floor inside the yard. There will definitely be no quality problems. The price of concrete may be higher. For example, the yard area at home is not very large, so you can choose self-leveling concrete floor and self-leveling new decorative materials. The effect of cement floor is particularly good, and it is more labor-saving and labor-saving.

The use of self-leveling concrete floor is not limited by the size of the area, and the concrete floor is particularly good, and there will be no sand, cracks and peeling.
