Problems solved by technology

[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, while accelerating the corrosion of steel bars, resulting in cracking and water seepage of building materials

Abstract

The invention discloses a building panel doped with a complex mineral. The panel is characterized by comprising the following processes: weighing 282g of material cement, 18g of prepared cement complex mineral additive, 750g of sand, 4g of polypropylene fiber and 3g of naphthalene water reducer according to the ratio; feeding the raw materials to a conical twin-screw mixer to evenly agitate according to the ratio, wherein the agitating time is 50 minutes. The building panel doped with the complex mineral disclosed by the invention has the functions of efficiently preventing water, preventing moisture, expanding, anti-cracking, anti-seepage and the like, and is free of corrosive action on a reinforcing steel bar.

Description

technical field [0001] The invention relates to a building board mixed with composite minerals, 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 invention is to overcome the deficiencies of the prio...
