Concrete suitable for severe working conditions and preparation method thereof
The invention discloses concrete suitable for severe working conditions and a preparation method thereof. The concrete comprises the following components: cement, gravel, sand, fly ash, a water reducing agent, expansive clay, nano cellulose, silicon dioxide and composite fibers, the composite fiber comprises graphene oxide modified glass fiber and modified polyvinyl alcohol fiber; the preparation method of the graphene oxide modified glass fiber comprises the following steps: soaking glass fiber in a graphene oxide dispersion liquid for 5-12 minutes, and drying to obtain the graphene oxide modified glass fiber, the preparation method of the modified polyvinyl alcohol fiber comprises the following step: forming a polyvinyl acetate film on the surface of the polyvinyl alcohol fiber. According to the scheme provided by the invention, the temperature difference tolerance, the cracking resistance and the mechanical strength of the concrete are effectively improved through synergistic use of all the components.
本发明公开了一种适用于恶劣工况的混凝土及其制备方法。所述混凝土包括以下组分：水泥、碎石、砂、粉煤灰、减水剂、膨胀粘土、纳米纤维素、二氧化硅和复合纤维；所述复合纤维包括氧化石墨烯改性玻璃纤维和改性聚乙烯醇纤维；所述氧化石墨烯改性玻璃纤维的制备方法包括以下步骤：将玻璃纤维浸泡在氧化石墨烯分散液中5‑12min，干燥后即得；所述改性聚乙烯醇纤维的制备方法包括以下步骤：在聚乙烯醇纤维表面形成聚醋酸乙烯酯膜。本发明方案通过各组分的协同使用，有效的提高了混凝土的温差耐受性、抗开裂性以及力学强度。
