The main reason is that the current waterproof materials and cement plus The agent generally contains Cl-,,,,, and K+ ions are too heavy, and when added to the cement, it reacts with the active silica in the concrete to form an alkali silicate gel and cause the concrete to expand and crack. This is a common problem in engineering. Alkali-aggregate reaction, while accelerating the corrosion of steel bars, resulting in cracking and water seepage of building materials

Abstract

The invention discloses a preparation method of a plate for a building. The plate for the building is doped with composite minerals. The preparation method of the plate for the building is characterized by comprising the following steps: weighing raw materials, namely cement, the prepared cement composite mineral additive, sand, polypropylene fibers and a naphthalene water reducer, in ratio; and putting the raw materials into a conical double helix stirring machine in the ratio, and uniformly stirring for 50 minutes. The composite-mineral-doped plate for the building has efficient waterproof, dampproof, expansion, crack-proof and impervious functions and also has no rusting effect on reinforcing steel.

Description

technical field [0001] The invention relates to a building plate mixed with composite minerals, namely a preparation method of the building plate, which belongs to the field of building material manufacturing. Background technique [0002] During the project, the basements, roofs, roads and bridges of many buildings did not reach the designed service life, and some projects were seriously damaged after only a few years of use and had to be repaired. The main reason is that the current waterproof materials and cement plus The agent generally contains Cl-,,,,, and K+ ions are too heavy, and when added to the cement, it reacts with the active silica in the concrete to form an alkali silicate gel and cause the concrete to expand and crack. This is a common problem in engineering. Alkali-aggregate reaction also accelerates the corrosion of steel bars, resulting in cracking and water seepage of building materials. Contents of the invention [0003] The purpose of the present in...
