Modification method and application of rubber concrete
The invention discloses a modification method and application of rubber concrete. The modification method comprises the following steps: preparing metallized rubber, preparing a bonding medium solution, carrying out dry mixing and uniform stirring on rubber and metal powder, adding the bonding medium solution into a mixture of rubber and metal powder, stirring, adding excessive cement into the mixture obtained in the S3, stirring until the particles are mutually dispersed, standing for 28 days for later use, preparing concrete and mixing the metallized rubber with cement, sand, stone and waterto prepare the concrete. According to the modified rubber concrete, the bonding interface structure of the rubber concrete is changed, the implementation is convenient, and the modified rubber concrete can be quickly prepared by workers on an engineering site. Raw materials are cheap and easy to obtain and can be obtained locally, according to the modified rubber concrete, the compressive strength and breaking strength are greatly improved, the bending deformation capacity is greatly improved, the mid-span deflection can be improved by 500%, and the strength attenuation value is reduced by 50%-75% compared with unmodified rubber concrete.
本发明公开了一种橡胶混凝土的改性方法及其应用，该改性方法包括以下步骤：配制金属化橡胶：配制粘结介质溶液；将橡胶与金属粉进行干混合搅拌均匀；将粘结介质溶液加入橡胶与金属粉的混合物进行搅拌；将S3获得混合物加入过量的水泥进行搅拌至颗粒彼此分散开来；静置28天后待用；配置混凝土：将金属化橡胶与水泥、砂、石和水混合后制备混凝土。本发明的改性橡胶混凝土改变了橡胶混凝土的粘结界面结构，便于实施，工程现场由工人即可快速制备；原材料廉价、易得，可就地取材；本发明的改性橡胶混凝土抗压强度、抗折强度大幅度提高，弯曲变形能力得到极大改善，跨中挠度可提高500％，相对未改性橡胶混凝土，强度衰减值缩小50％‑75％。
