Conductive concrete material and preparation method thereof

Abstract

The invention belongs to the field of functional materials and provides a conductive concrete material and a preparation method thereof. The material is a novel concrete material based on a graphdiynenanomaterial and comprises the following raw materials: 200-800 parts of Portland cement, 500-1600 parts of standard sand, 10-25 parts of a dispersing agent, 3-8 parts of the graphdiyne nanomaterialand 250-350 parts of mixing water. The method comprises the following steps: firstly, polyoxyethylene nonylphenylether as the dispersing agent and the graphdiyne nanomaterial are dissolved in the mixing water, ultrasonic processing is performed, and a waterborne dispersed suspension which is uniformly dispersed is prepared; secondly, the waterborne dispersed suspension is added to the Portland cement for stirring, stirred graphdiyne cement paste is poured into a mold and is vibrated and compacted to be molded; finally, a sample is subjected to standard curing, and demolding is performed. The prepared concrete material has excellent conductivity and higher strength, electrical resistivity of the concrete material is reduced obviously, and practical engineering application of novel conductive concrete is facilitated.

Description

technical field [0001] The invention belongs to the field of functional materials, and designs a conductive concrete material, in particular to a conductive concrete material based on a graphyne nanomaterial and a preparation method thereof. Background technique [0002] With the development and progress of modern society, large-scale ground buildings such as high-rise buildings, roads, bridges and dams have developed rapidly. high demands. Concrete is the most commonly used building structure material. If cracks or other damage processes occur inside, it is not easy to detect from the outside, which poses a potential threat to the performance and safety of large-scale buildings on the ground. At the same time, in the snow and ice weather in winter, the ice and snow covering the road surface will easily cause the friction between the wheels and the ground to decrease, threatening travel safety. At the same time, the thawing cycle will cause the volume expansion and contract...
