Why are my cement Pots cracking

As you know, cement flower pots are made of cement, sand, water or some special functional materials.

The 3 Most Common Reasons Cement Plant Pots Crack

1. Incorrect ratio of raw materials

The raw material of cement flower pots is not just cement. The main function of cement is to coagulate. If only flower pots made of cement are used, although the appearance is very smooth, the flower pots are easy to chalk and crack.

2. Shrinkage deformation

Concrete (a mixture of cement, sand, and water) will always expand and deform in water, and will always shrink and deform in air. Therefore, when the flowerpot dries and hardens, the volume of the cement paste in it will shrink.

3. The maintenance is not in place

The new pots are not maintained after they are made.

How to prevent flower pots from cracking?

1. The ratio of raw materials for cement flower pots is correct

The ratio of cement and sand can be 1:1--1:2, the content of cement should not be too high, and ordinary river sand can be used directly for sand.

2. Control the cement content and increase the sand content

The sand should not be too fine, it is best to mix coarse and fine particles, otherwise there will be tears when shrinking. And the larger the particle size of the sand, the better the air permeability and water permeability of the flowerpot! Be sure to use clean, free sand.

3. New cement flower pots need maintenance

After the Cement Flower Pot is demolded, it also needs to be maintained in the early stage. Generally, the most common and easiest way is to soak it in water. The curing time is about 3-7 days, so that the shrinkage can be reduced, and the shrinkage of the small flowerpot is not easy to crack.

4. The pots are painted in time
