Crash barrier slip form construction concrete as well as preparation method and application thereof
The invention discloses crash barrier slip-form construction concrete as well as a preparation method and application thereof. The concrete comprises cement, fly ash, fine aggregate, coarse aggregate, water and an additive, wherein the mass ratio of the cement to the fly ash to the fine aggregate to the coarse aggregate to the water to the additive is (300-350): (40-60): (800-820): (1050-1100): (130-140): (5-6). The concrete has the advantages of being extremely small in slump, easy to form and incapable of collapsing, and can meet the requirement for keeping the plastic state of the concrete in the long-distance transportation process, so that the slip-form construction requirement is met. The concrete disclosed by the invention is suitable for preparing the crash barrier by a slip-form construction process, the slip-form construction requirements are met, the slip-form construction process can be applied to crash barrier construction, the slip-form construction can replace traditional construction, one slip-form paver can construct more than 240 m every day, and the construction efficiency, the construction safety and the economical efficiency are improved.
本发明公开了一种防撞栏滑模施工混凝土及其制备方法和应用，该混凝土包括水泥、粉煤灰、细集料、粗集料、水和外加剂；其中，各原料的质量比为水泥：粉煤灰：细集料：粗集料：水：外加剂＝300～350:40～60:800～820：1050～1100：130～140：5～6。本发明的混凝土具有坍落度极小，易成型且不能倒塌的优点，能满足长距离运输过程中混凝土保持塑性状态的需求，从而满足滑模施工要求。本发明的混凝土适用于滑模施工工艺制备防撞栏，满足滑模施工要求，使滑模施工工艺在防撞栏施工中得以运用，使滑模施工代替传统施工成为现实，一台滑模摊铺机每天可施工240m以上，提高了施工效率、施工安全性和经济性。
