Problems solved by technology

Patent CN201310411979.7 adds 5 to 7% feldspar to the preparation of oil sludge sand foam concrete blocks, but since feldspar is not the main component, the amount used is small, which cannot solve the waste pollution caused by a large amount of feldspar waste piled up

Abstract

The invention provides a feldspar waste material concrete and a preparation method thereof. The feldspar waste material concrete comprises the following raw materials: feldspar waste material, clay, cement, phenolic fiber, polyvinylidene chloride fiber, water and an additive, and the additive is composed of a sulfonated acetone-formaldehyde high efficiency water reducer, a sodium meta aluminate accelerator, a citric acid-chitosan adhesive and diatomite powder. The method solves the utilization problem of feldspar waste material, source of the raw materials is stable and wide, production cost is reduced, resource is saved, environment can be protected; production process is simple and feasible, operation is convenient, a mixing material integrated with ceramic, glass and stone can be prepared after mixing and calcining clay and feldspar powder, and is crushed to be the sandstone material mixing material as a concrete frame, phenolic fiber, polyvinylidene chloride fiber and the additive are added, so that the concrete has the advantages of high intensity, antifreezing performance, fire resistance, and good water proofness, and is suitable for high mine workings, railway tunnel, diversion culvert and underground engineering construction with high concrete performance requirement.

Description

technical field [0001] The invention belongs to the technical field of concrete and waste recycling, and relates to a feldspar waste concrete and a preparation method thereof. Background technique [0002] Feldspar is the result of long-term movement of the earth's crust in nature. Feldspar has a high silica content, up to 67%, and high compressive strength. The basic structure of feldspar is tetrahedral, with structural stability and other characteristics. It is usually used in the manufacture of ceramics, glass, Abrasive material. Some feldspar deposits contain too many impurities and cannot be discarded as traditional ceramics, glass and other raw materials. A large number of feldspar wastes not only cause serious pollution to air, water and soil, but also occupy a large amount of farmland, causing waste. . Therefore, it is necessary to study how to use feldspar waste rationally and effectively to make feldspar waste "turn waste into treasure". [0003] In construction...
