A kind of anti-radiation high-strength concrete and its production process

Abstract

A radiation-proof high-strength concrete provided by the invention, said concrete comprises the following components by weight: 300-350 parts of cement, 40-55 parts of mixed fibers, 80-110 parts of fly ash, 830-930 parts of gravel, crushed 1120-1150 parts of stone, 6-7 parts of water-retaining agent and 200-230 parts of water; the mixed fibers include stainless steel fibers, wood fibers and polyvinyl alcohol fibers, and iron ore is included in the gravel and crushed stones; stainless steel fibers are used, It makes the concrete have excellent anti-radiation ability, and at the same time, the stainless steel fiber, wood fiber and polyvinyl alcohol fiber form a mixed fiber, which provides excellent bending strength and compressive strength for the concrete, and iron ore is mixed into gravel and gravel to replace part of the Gravel and gravel reduce the amount of gravel and stones used, and at the same time make the concrete have better radiation resistance.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a radiation-proof high-strength concrete and a production process thereof. Background technique [0002] At present, radiation exists in the entire universe. The sources of radiation include natural radiation and artificial radiation. Natural radiation includes cosmic rays, gamma rays, radon, and alpha particle rays in the environment. Artificial radiation has applications in nuclear power, military, education, scientific research, and medical treatment. Various rays such as α, β, γ, X and neutron rays produced in the human body, long-term exposure to these rays can induce cancer, leukemia and multiple myeloid cancer, malignant tumors, thyroid dysfunction, infertility, miscarriage and childbirth Defects and other human terminal diseases, but also can induce plant gene mutations and endanger the growth of crops. [0003] In order to prevent these rays, when manufactur...

Problems solved by technology

[0003] In order to prevent these rays, when manufacturing buildings, mineral admixtures of heavy metal elements will be added to the concrete, such as Mg, Ti, 14C, 55Fe and 60Co and Cu can all improve the radiation resistance of concrete, so that concrete can play a role in radiation protection Therefore, the buildings made of this concrete can have excellent anti-radiation performance, but in the actual use process, metal powder is added to the concrete, which can only make the concrete have anti-radiation ability.
