Filed: 2021-01-07
Abstract: The present invention relates to a blending technology for producing a mixed binder (resin)-added molded material for molding and restoring partial damage and omission, such as concrete roads and airports. Mixing materials (cement, silica sand and fine aggregate) are mixed according to the standard mixing ratio. By independently adding a mixed binder (resin) to the mixed mixture, the finished product mixed binder (resin)-added concrete expedited molding with good storage and workability is produced and used. The present invention is improved technology and quality of existing concrete repair materials using existing polymers/resins, etc. As for existing methods, due to the lack of resin-added manufacturing synthesis technology, there is a risk of premature condensation and material loss before construction due to chemical reactions, temperature, humidity, and changes in resin and aggregate aggregates during resin-added manufacturing. After mixing a binder resin (main material + hardener) at a construction site, compounding materials (silica sand, gravel, silica sand special powder, additive materials), etc. are mixed, mortar is formed through a complex process of stirring mixed binder resin and aggregate, and storage and high-quality workability cannot be expected. In order to resolve this, the present manufacturing technology was developed, and a resin-added finished product (concrete improvised molding material) is simply constructed by adding an appropriate amount of water at the construction site to create mortar. The ripple effect of manufacturing technology development can be expected to shorten the construction period, reduce construction costs, improve quality, and secure technical construction. Export packing is easy due to the long-term storage of materials, which reduces logistics costs and has long-term effects economically and technically.
