? ??鋼纖維是一種新的**性能的纖維品種。鋼纖維的配合對比方法有些與普通的混泥土相同,但由于它的特性強度雙控**,步驟還需要更繁瑣一些。鋼纖維摻入量根據設計要求的彎拉強度確定,單位的用水量和砂率與纖維摻量有關,每摻入0.5的鋼纖維,單位用水量需要加入6kg,砂量增加2。
? ? 鋼纖維在加工的過程中受到高熱和冷卻,相當于淬火的狀態。所以鋼纖維的硬度要高,在混泥土攪拌的時候一般不會出現打彎的狀態。鋼纖維做成鉤狀可以更有效的對混泥土產生附著。
? ? 裂開的鋼纖維混泥土構件在潮濕的環境中,裂縫處的混泥土容易碳化,一旦有水,濕氣滲入鋼纖維會出現銹蝕,不但影響鋼纖維混泥土的強度,也大大的縮短了壽命。鋼纖維混泥土與機體的粘接是物理性的,以摩擦剪力的傳遞為主。鋼纖維混泥土的質量上去了就突出了粘接性的重要性。
?
? ? ??鋼纖維的抗彎拆功能,鋼纖維應該經受直徑毫米鋼棒彎拆九十度保持不斷,在檢驗的時候每批不能少于10根。
? ? ??優質鋼纖維的長度不超過規范長度的百分之十,每批檢驗不能少于10根。
? ? ??優質的鋼纖維雜質含量少,鋼纖維的外表無油污,不用含有有害物質的鍍物或者是影響鋼纖維與混凝土粘接的雜質。
? ? ??鋼纖維的抗拉強度的檢查,鋼纖維的抗拉強度不能**380mpa。
?
? ? ??公路橋梁:公路路面、橋面鋪裝,箱形拱橋拱圈、連續箱形梁澆筑。
? ? ??水工大壩:地下廠房、水工隧洞襯砌,水流沖刷磨損部位、閘門、閘槽、渡漕、大壩防滲面板。
? ? ??鐵路工程:預應力鐵路軌枕,雙塊式鐵路軌枕。
? ? ??港口及海洋工程:鋼管樁防蝕層、碼頭設施、海底混凝土設施。
? ? ??隧道及礦井工程:水工隧洞襯砌、礦井巷道、鐵路、公路隧道襯砌。
? ? ??管道工程:離心管、振動和擠壓管、泵管、鋼襯鋼纖維混凝土壓力管。

Steel fiber is a new kind of high performance fiber variety. The comparison method of the steel fiber with some ordinary concrete is the same, but because of its characteristic strength double control standard, the step also needs to be more complicated. According to the design requirements of the steel fiber content, the amount of water and sand ratio of the unit is related to the fiber content, and 0.5 of the steel fiber is added, the amount of water needed to add 6kg, the amount of sand is increased by 2.
The steel fiber is subjected to high heat and cooling in the process of machining, which is equivalent to the state of quenching. So the hardness of steel fiber to be high, when in the mixed soil mixing is generally not a bending state. Hook shaped steel fiber can be more effective in the production of mixed soil.
Mixed cracked steel fiber soil component in a humid environment, the cracks of mixed soil is easy to be carbonized, if there is water, moisture penetrating into steel fiber will rust, not only affect the strength of steel fiber concrete, also greatly shortened the life span. The bonding between the steel fiber concrete and the body is physical, and the transfer of the friction shear force is the main method. The quality of the steel fiber concrete has highlighted the importance of bonding.
?
The steel fiber bending demolition function, steel fiber should be subjected to diameter mm steel rod bending removed ninety degrees to keep, in test each batch of not less than 10.
The high-quality steel fiber length does not exceed the standard length of ten percent, each batch test does not less than 10.
Quality the of steel fiber impurity content is less, the appearance of the steel fiber without oil, do not contain harmful substances of plating or is the effect of steel fiber and concrete bonding impurities.
The tensile strength of the steel fiber inspection, tensile strength of steel fiber is not less than 380mpa.

Transport and handling: in the transport process, not drag hook, should prevent mixed with the solid material, strong vibration, friction, hit, hit, forbid throwing should be lightly armed light discharge, to reduce the breakage of packing, the impact of the use.
Storage: should be stored in a cool and dry place, to prevent internal and external packaging bag break, prevent moisture and adsorption of other substances in the air, affect the use effect. It is strictly prohibited to mix with poisonous and harmful gas or volatile matter, and keep away from the source of pollution.
