Abstract

The invention provides a nano / inorganic composite material, which consists of the following ingredients by weight portions: 1-15 portions of carbon nano materials, 40-120 portions of oxide materials and 60-180 portions of sulfate materials, wherein the carbon nano materials are calculated by carbon nano active ingredients in the materials. The invention additionally provides a preparation method for the nano / inorganic composite. When the nano / inorganic composite material is used as engineering materials or engineering auxiliary materials, the nano / inorganic composite material has the performances of static electricity conduction, leakage prevention, high strength and concrete contraction compensation. The composite material has the advantages of low production cost and simple operation process, and can be widely used as functional building materials in the engineering field such as mines, tunnels and the like.

Description

technical field [0001] The invention relates to a nano / inorganic compound and a preparation method thereof. It belongs to the field of inorganic materials science. technical background [0002] The development of concrete materials has a history of more than 200 years. Due to its own advantages, high strength, good durability, wide source of raw materials, simple process, low cost, and suitable for various natural environments, it has been greatly developed. However, concrete is a porous substance with many pores, and when the concrete dries, it is easy to shrink and cause cracks. These pores and cracks will become channels for water seepage and leakage in the later period. Long-term water seepage will lead to cracks inside the concrete. Calcium hydroxide dissolves and erodes the internal structure of concrete, which not only affects the safety of the structure, but also shortens the service life of the project. [0003] At present, some people use Portland cement and othe...
