Problems solved by technology

The annual discharge of copper slag in my country is huge, and most of them are in the state of accumulation and storage. At present, the stock of copper slag in my country has already exceeded 50 million tons, which not only occupies land, pollutes the environment, but also causes a huge waste of resources.

Abstract

The invention belongs to the field of concrete, and particularly discloses radiation-proof concrete and a preparation method thereof. The concrete is prepared from the following materials in parts byweight: 300-350 parts of cement, 900-1,200 parts of fine aggregate, 1,200-1,500 parts of coarse aggregate, 60-80 parts of fibers, 10-20 parts of a neutron absorber, 0.4-0.6 part of a water reducing agent, and 145-165 parts of water. The radiation-proof concrete prepared by the method is in compliance with a strength requirement of concrete C30 without a segregation phenomenon, good in slump degreeand extended degree, wherein a volume weight ranges between 2,900 and 2,950 kg*m<3>, and is in compliance with a volume weight requirement to the radiation-proof concrete. In addition, the radiation-proof concrete has the characteristics of excellent working performance, good radiation-proof performance, low cost, fire resistance, crack resistance and the like, and is beneficial to solve problemsof traditional radiation-proof concrete that segregation is easy, homogeneity is poor, workability is not good and the like, and an application problem in the environment with fire-proof and anti-crack requirements.

Description

technical field [0001] The invention belongs to the field of concrete, and specifically discloses a radiation-proof concrete and a preparation method thereof. Background technique [0002] Radiation exists throughout the universe and can be divided into natural radiation and artificial radiation. Natural radiation mainly comes from cosmic rays, etc. Artificial radiation mainly comes from α, β, γ, X and neutron streams and other rays produced in the process of applying nuclear technology in nuclear power, military, education, medical treatment, scientific research and other fields. After being exposed to these rays for a long time, it is easy to induce cancer, leukemia, thyroid dysfunction, infertility, birth defects and other diseases, and it is also easy to induce gene mutations in other animals or plants. In order to prevent radiation from harming human beings, when building buildings with radiation sources, it is generally necessary to install radiation-proof materials t...
