concrete bleeding的用法详解
Concrete Bleeding是指混凝土的渗水现象。它是指混凝土中的水分过多，把水分从混凝土表面渗出，组成水汽和水膜，使混凝土表面出现水珠。
Concrete bleading is usually caused by too much water in the concrete mix, over-vibration of the concrete, or excessive water during curing. To prevent concrete bleeding, the amount of water in the concrete mix should be reduced; the concrete should not be over-vibrated; the curing temperature should be kept within the acceptable range.
To prevent concrete bleeding, it is recommended that the concrete used should be of the highest quality, with a low water to cement ratio, and it should be well compacted and cured.
In addition, the use of a water repellent admixture can also reduce concrete bleeding by reducing the surface tension and allowing the water to penetrate deeply into the concrete rather than forming puddles on the surface.
Concrete bleeding can be reduced by using high-quality aggregate and ensuring the correct proportions of cement and water are used, as well as ensuring proper compaction of the concrete during construction. Additionally, proper curing techniques can further reduce the amount of water that is released from the surface.
