Abstract

The invention discloses a preparation method of emergency hydraulic engineering reinforced concrete, which is prepared from the following raw materials in parts by weight: 25 to 35 parts of water, 20 to 25 parts of cement, 10 to 15 parts of a gel material, 10 to 15 parts of aggregate, 5 to 10 parts of a foaming agent, 15 to 20 parts of sand, 5 to 10 parts of accelerator, 5 to 10 parts of polypropylene fiber, 2 to 5 parts of a water reducing agent and 5 to 10 parts of an early strength agent. The preparation method comprises the following steps: S1, firstly, arranging a template according to the standard of reinforced concrete construction, arranging a plurality of separation layers around the template, arranging the steel bars in the separation layers of the template, and bundling the steel bars into a ring shape through separation plates, and S2, fully mixing and uniformly stirring the water, the cement, the gel material, the aggregate, the foaming agent and the sand, and carrying out molding, so as to obtain a first mixture . The emergency water conservancy project reinforced concrete is good in solidification effect, short in solidification forming time, reasonable in matching, convenient to use and convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete, in particular to a method for preparing reinforced concrete for emergency water conservancy projects. Background technique [0002] Reinforced concrete, often referred to as reinforced concrete in engineering, refers to a composite material formed by adding steel mesh, steel plate or fiber to concrete to work together to improve the mechanical properties of concrete. The most common form of concrete. [0003] The solidification effect of reinforced concrete in the prior art is poor. When an emergency situation occurs, reinforced concrete cannot effectively function. Therefore, we propose a method for preparing reinforced concrete for emergency water conservancy projects to solve the above-mentioned problems. Contents of the invention [0004] Based on the poor solidification effect of reinforced concrete in the background technology, and the technical problem that reinforced concre...
