今天在這里就由小編來為大家介紹一下有關(guān)復(fù)合井蓋的優(yōu)點性能的一些相關(guān)信息，希望可以幫助大家在以后購買使用的時候可以有所用到，請大家跟隨小編一起來了解一下以下內(nèi)容介紹吧：

鋼纖維混凝土復(fù)合井蓋是原鋼筋混凝土檢查井蓋的改良產(chǎn)品。它是在混凝土中加入長約2厘米左右的鋼纖維，大量的鋼纖維分散在混凝土中。而形成不規(guī)則的放射狀分布。從而使混凝土強度得到加強。大大提高了混凝土的韌性。其抗彎拉強度、抗疲勞開裂強度等都得到了很大的提高， 同時可以減小裂縫寬度。

為了減少鋼纖維混凝土復(fù)合井蓋在使用過程中崩邊現(xiàn)象，一般在復(fù)合井蓋外邊加金屬框。鋼纖維混凝土復(fù)合井蓋的強度要比同配比下的普通混凝土復(fù)合井蓋提高了30%以上，各項性能接近了鑄鐵復(fù)合井蓋。

Xiaobian here today to tell you about the advantages related to the performance of composite covers some of the relevant information, I hope to help everyone in the future use when you can buy some used, please follow Xiaobian a look at the following description it:

Steel fiber reinforced concrete composite covers the original reinforced concrete manhole covers of improved products. It is adding about 2 centimeters of steel fibers in concrete, a lot of steel fibers dispersed in the concrete. And an irregular radial distribution. So that the strength of concrete has been strengthened. Greatly improving the toughness of concrete. Flexural tensile strength, fatigue strength and so get cracking greatly improved, while reducing the crack width.

In order to reduce steel fiber reinforced concrete composite covers chipping phenomenon in the course of the general increase in composite covers the outside of the metal frame. Strength of steel fiber concrete composite covers the same proportion than under ordinary concrete composite covers improved by more than 30%, the performance close to the iron composite covers.
