Abstract
The invention relates to a microorganism corrosion experimental device and an experimental method for concrete. The microorganism corrosion experimental device is characterized by comprising a corrosion reaction generation cabin, an experimental gas generation device and a medium solution replacing device, wherein the experimental gas generation device for supplying an experimental gas into the corrosion reaction generation cabin is communicated with the corrosion reaction generation cabin through a corrosion-resistant gas guide tube; the medium solution replacing device for replacing a medium solution inside the corrosion reaction generation cabin is communicated with the corrosion reaction generation cabin through another corrosion-resistant gas guide tube. By adopting the microorganism corrosion experimental device and the experimental method, the technical blank that in the prior art no concrete corrosion experimental special equipment for microorganisms is available is made up, and special experimental devices for further studying corrosion characteristics of microorganisms to concrete is provided for technicians.
Description
technical field [0001] The invention belongs to the technical field of microbial corrosion concrete characteristic experiments, and in particular relates to a concrete microbial corrosion experimental device and an experimental method. Background technique [0002] The corrosion resistance of concrete is one of the important indicators reflecting the durability of concrete, which is related to the service life of concrete structures. Commonly referred to as concrete corrosion generally refers to chemical medium corrosion. The ability of concrete to resist chemical media attack is generally lower than other forms of corrosion. In the last century, many scholars have done a lot of research work on the corrosion of concrete by chemical media, and basically found out the influence laws of various factors, but the corrosion media are mainly limited to inorganic acids, alkalis, salts and organic acids and other media, and no microorganisms are involved. effect on concrete.
