低溫對混凝土有什麼影響呢？

混凝土具有原料豐富，價格低廉，生産工藝簡單等特點，它的用途也是非常的廣泛。，同時，混凝土還具有抗壓強度高，耐久性好，強度範圍廣等的特點。這些特性使它不僅可以用于各種土木工程，而且還可以應用于造船，機械工業等領域。

Concrete has rich raw materials, low price, simple production process and other characteristics, its use is also very wide. At the same time, concrete also has the characteristics of high compressive strength, good durability and wide range of strength. These characteristics make it not only can be used in various civil engineering, but also can be used in shipbuilding, machinery industry and other fields.

那低溫對混凝土有什麼影響呢？？對此你了解多少呢？今天自動混凝土攪拌車廠家的小編就這個問題給你介紹一下，希望對你有所幫助。

What effect does low temperature have on concrete?? How much do you know about it? Today, the automatic concrete mixer manufacturers Xiaobian on this issue to introduce you, I hope to help you.

1.低溫條件對混凝土強度的影響低溫條件會降低水泥的水合速率，從而影響混凝土的強度發展。

1. The influence of low temperature on the strength of concrete. Low temperature will reduce the hydration rate of cement, thus affecting the strength development of concrete.

2.低溫條件對混凝土早期性能的影響已通過實驗證明：澆築混凝土時，如果溫度較低，則初始凝結時間和zui終凝結時間會延長，對于混凝土的溫度也會延長，後面的凝固時間會更加的明顯。

2. The influence of low temperature on the early performance of concrete has been proved by experiments: when pouring concrete, if the temperature is low, the initial setting time and Zui final setting time will be prolonged, and the temperature of concrete will also be prolonged, and the later setting time will be more obvious.

3.低溫條件對混凝土抗凍性的影響混凝土的抗凍性與混凝土的凍融循環時的年齡有關，而混凝土的抗凍性受早期的影響。到多次凍融循環，循環成熟混凝土的抗凍性之間沒有線性比例關系。

3. The influence of low temperature on the frost resistance of concrete. The frost resistance of concrete is related to the age of concrete in freeze-thaw cycle, and the frost resistance of concrete is affected by the early age. There is no linear proportional relationship between the frost resistance of cyclic mature concrete and multiple freeze-thaw cycles.

4.低溫條件對混凝土體積穩定性的影響。對于低溫條件下的混凝土結構，表面溫度的降低速度明顯大于内部溫度的降低速度，從而導緻更大的溫度梯度和由此産生的溫度應力。抗拉強度不足以抵抗該溫度下的應力，混凝土表面會出現不規則的可見或不可見裂紋。

4. The influence of low temperature on the volume stability of concrete. For the concrete structure at low temperature, the decreasing speed of the surface temperature is obviously faster than that of the internal temperature, which leads to a larger temperature gradient and the resulting temperature stress. The tensile strength is not enough to resist the stress at this temperature, and irregular visible or invisible cracks will appear on the concrete surface.
