At present, the vast majority of brick machine factories pay little attention to the late maintenance of bricks. Due to site and funding constraints, most brick factories use natural conservation. These brick factories believe that natural conservation is as simple as watering. The result is: their machines and equipment are good, their raw materials ratio is no problem, the produced embryos are good, but after the curing, the finished products have problems such as peeling, cracking, falling corners and falling edges.


Post-conservation of concrete brick, in an artificial condition of certain humidity and temperature, brick embryos accelerate hardening and strength growth. It is itself the result of cementation. If the condition does not exist in the surrounding environment, the concrete brick is manually cured.

There are two methods for curing concrete bricks, one is natural conservation and the other is steam curing. Natural conservation is low in cost and easy to operate, so it is widely used.

Under normal temperature conditions, during the curing of concrete bricks, it is necessary to take measures such as wrapping film, watering and spraying water to moisturize. Usually it can be shipped after ten days. Maximum strength was reached at 28 days.


When the temperature is too low, it is not conducive to the production and maintenance of concrete bricks. The finished products are easily damaged by freezing and affect the quality of the products. Therefore, the following problems should be noted in the production of concrete bricks in winter:

1. If the temperature is too low, it will directly affect the quality of the cement bricks. When mixing, it is necessary to add the external admixture (antifreeze). If the conditions are not met, the production should be stopped.

2. The materials used in the production of concrete bricks should avoid icing. Sand, stone, fly ash and other materials should be used with the mix, do not accumulate too much. When mixing, it should be sprayed with warm water to prevent ice and snow from entering the mixer and affecting the quality of the brick.

3. The finished bricks must be covered with moisturizing materials. When the temperature is below zero, the raw materials and finished products should be covered with warmth. The curing time should not be less than 45 days. The strength test must be done before use. The storage of various materials and the placement of finished products in the site shall be standardized. Frozen bricks that are soaked in water cannot be used.
