Does the water-cement ratio affect the strength of the concrete?

2018-05-10 Views:

Water-cement ratio refers to the ratio of the amount of water in cement concrete to the amount of cement. In the unit concrete mix, after the ratio of the aggregate is determined, that is, when the amount of the cement slurry is a fixed value, the water-cement ratio determines the consistency of the cement slurry.
When the water ash is relatively small, the cement slurry is thicker, and the fluidity of the concrete mixture is also less. When the water-cement ratio is less than a certain limit value, it cannot be guaranteed to compactly form under a certain construction method; conversely, the water ash is relatively large. Although the cement slurry is relatively dilute, the fluidity of the concrete mixture is relatively large, but the cohesive property and water-retaining property are deteriorated.
When the water-cement ratio is greater than a certain limit, serious segregation and bleeding will occur. Therefore, in order for the concrete mixture to be compacted, the water-cement ratio used should not be too small. To ensure that the concrete mixture has good cohesion and water retention, the water-cement ratio used should not be too large.
Since the change of water-cement ratio will directly affect the strength of cement concrete, in practical projects, in order to increase the fluidity of the mixture, the water-cement ratio must be kept constant while increasing the amount of cement, otherwise it will To significantly reduce the quality of concrete, the fluidity of the concrete mixture must not be adjusted by simply changing the amount of water used.
In the normal use range, when the amount of water in the concrete is constant, the water-cement ratio changes in a small range, and the fluidity of the concrete mixture has little effect.
