Abstract

The invention relates to high anti-cracking large volume radiation-proof concrete. The concrete is characterized by comprising water, gelled material, fine aggregate, coarse aggregate, water reducing agent and fibers, wherein the gelled material consists of cement and mineral admixture, and the fibers consist of steel fibers and lead borate polyethylene fibers; and the components have the following proportion: 150 to 170 kg / m<3> of water, 250 to 450 kg / m<3> of cement, 100 to 300 kg / m<3> of mineral admixture, 1,000 to 1,800 kg / m<3> of fine aggregate, 1,500 to 2,200 kg / m<3> of coarse aggregate,water reducing agent in an amount which is 0.6 to 1.2 percent of the total mass of the gelled material, steel fibers in an amount which is 0.5 to 1.5 percent of the total volume of the gelled material, and lead borate polyethylene fibers in an amount which is 0.8 to 1.2 percent of the total volume of the gelled material. The concrete has good physical property and good cracking resistance, and further enhances the radiation resistance.

Description

technical field

[0001] The invention belongs to the field of radiation shielding building materials, and in particular relates to a high-crack-resistant large-volume radiation-proof concrete and a construction process thereof. Background technique

[0002] With the deepening of the international energy crisis and the looming threat of climate change, nuclear energy, as a clean, efficient and low-carbon energy, is developing steadily in the field of nuclear power generation. Moreover, nuclear facilities are playing an increasingly important role in various fields such as medical treatment, military affairs, and scientific research by virtue of their excellent multifunctional characteristics (detection, life assessment, power generation, etc.). However, due to the problem of ray radiation in nuclear reactors, there are some safety threats to the human body and the surrounding environment. Therefore, while vigorously developing nuclear facilities, it is necessary to conduct in...
