Reasons for ground unevenness and treatment methods

The flatness of the ground is very important in daily work and life. If the ground is uneven, high and low, or pits, it will affect the smooth operation of the forklift or the vehicle. Heavy objects may also be unstable due to the center of gravity. Dumping, and uneven ground will also affect the paving of the ground, easy to ash. In addition, in the construction of the ground, if the flatness of the ground is very bad, it is not conducive to the smooth operation of the floor grinder, and has a significant impact on the ground grinding effect.

[The reason for uneven ground]

1. The excessive consistency of the mortar is an important reason for the unevenness of the ground. Inappropriate process arrangement is also a problem that cannot be ignored. If the ground calendering time is too early or too late, the ground will be uneven. Improper maintenance can result in dehydration of the cement mortar which can result in a decrease in strength and wear resistance. The finished product is not well protected, and the cement mortar floor or the bonding force due to freezing damage forms loose particles. Raw materials are not required. The cement label is low, and the sand particle size is too fine, and the cement mortar surface layer will be sanded.

2. One of the reasons for the hollowing of the cement mortar floor is that the surface of the base layer is not clean and the surface of the base layer is too smooth. The adhesion between the base layer and the surface layer is insufficient, causing the surface layer to be hollow. The surface of the base layer is too dry or there is water on the surface of the base layer. When constructing cement mortar floor, a layer of plain cement mortar is generally applied on the surface of the base layer. If the brushing time is too early during operation, the brushed cement slurry has been air-dried and hardened, not only does not increase the cohesive force, but also acts as the base layer. The separation from the surface layer.

3. The cement with poor cement stability or just out of the kiln. The cement used has a large shrinkage when coagulated and hardened, and the mud content in the sand is too large. The volume of the soil in the cement mortar will shrink during the hardening and dehydration process, causing the surface of the floor to crack. Maintenance is not timely or not maintained. The ground will produce shrinkage cracks. When the cement mortar is too thin or unevenly stirred, the tensile strength of the mortar is lowered, and once the overall surface layer of the cement mortar is subjected to tensile stress, cracking of the cement surface layer occurs. Then there is the poor quality of the backfill.

These are some of the things to be aware of in the process of making cement floors. If the ground is already uneven, affecting people's work and life, then it must be dealt with in a timely manner.

The ground unevenness can be ground and leveled with a floor grinder, which has sufficient weight and strong cutting force; the grinding method of the four-headed planetary counter-grinding method is good, and the operation of the floor grinder on the ground is more stable; Walking and grinding, and the function of cruise control makes it possible to freely adjust the walking speed and speed. Even if the operator is different, as long as the parameters are set, the ground effect is the same. The super flat floor grinder is specially designed to deal with the problem of floor flatness, and its use makes the ground grinding more even and flat. The ground is more flat, which is more resistant to pressure and wear and easy to
