Concrete material, structure and simply-supported box girder
The invention relates to the technical field of concrete materials, in particular to a concrete material, a structure and a simply-supported box girder. The concrete material is prepared from raw materials such as a cementing material, mineral powder, fly ash, sand, gravel, water and a water reducing agent; concrete prepared by using the material disclosed by the embodiment of the invention has higher adhesive property in the specific use process, so that the change index of the deflection of a concrete beam structure which is relatively long and is prepared by technicians in the field by using the concrete material is stronger in the use process of the beam structure; the concrete material has a stronger bending resistance effect after being prepared into beam structures such as a beam section of a bridge, so that a longer beam section of the bridge can be prepared, and the problem that when the length of the beam section is greater than 40m, for example, a 64m or longer beam section needs to be prepared, the bending resistance effect is poor is solved. And the change range of values such as deflection and bending strength of the beam section directly made of concrete materials cannot meet the design requirements.
本发明涉及混凝土材料技术领域，尤其涉及一种混凝土材料、结构及简支箱梁，通过利用胶凝材料、矿粉、粉煤灰、砂、碎石、水以及减水剂等原料制成混凝土材料，在使用本发明示例的材料制备得到的混凝土在具体使用过程中能够具有更高的粘结性能，进而使得本领域技术人员在使用混凝土材料制备长度较长的混凝土梁结构的挠度在梁结构的使用过程中的变化指更强，混凝土材料在制备成桥梁的梁段等梁结构之后具备更强的抗弯效果，进而也就可以制备更长长度的桥梁梁段，解决了当梁段的长度大于40m，如需要制备64米或者更长的梁段时，直接采用混凝土材料制成的梁段的挠度、抗弯强度等数值的变化范围无法满足设计要求的技术问题。
