example 1

[0024] Get 100g of graphite, 300g of barite, 200g of hematite and 80g of serpentine and add them to a pulverizer to pulverize for 40 minutes to obtain a mixed powder. Add the mixed powder and biogas slurry to the fermenter at a mass ratio of 1:5, Sealed and fermented at ℃ for 5 days. After the fermentation was completed, the fermentation product was obtained. The fermentation product was moved into a centrifuge and centrifuged at a speed of 4000r / min for 5 minutes to obtain a precipitate, which was then put into an autoclave. Sterilize at 120°C for 15 minutes to obtain the sterilized material, that is, the modified filler, then take 15g of methallyl alcohol, 8g of boric acid and 100mL of anhydrous ether and add it to a three-necked flask equipped with a thermometer and a reflux device. Move it into an oil bath, control the temperature of the oil bath to 130°C, stir and mix for 5 minutes, add 3 mL of sulfuric acid solution with a mass fraction of 96% to the three-necked flask, s...

Abstract

The invention belongs to the technical field of preparation of building materials, and concretely relates to an anti-radiation concrete and a preparation method thereof. The preparation method comprises the following steps: mixing and crushing graphite and barite, carrying out sealed fermentation on the obtained crushed mixture and biogas slurry to obtain a fermentation product, centrifuging and sterilizing the fermentation product to obtain a modified filler, mixing and heating methylallyl alcohol, boric acid and anhydrous ether, reacting the obtained heated mixture with a sulfuric acid solution to obtain a product, distilling the product to obtain a methyallyl borate mixture, reacting and distilling the methyallyl borate mixture, N-hydroxymethylacrylamide and toluene to obtain an anti-segregation agent, mixing cement, the modified filler and fibers, stirring the obtained mixture, the anti-segregation agent, a water reducer and water, injecting the finally obtained mixture into a die, carrying out vibration molding, and demolding and curing the molded mixture to obtain the anti-radiation concrete. The anti-radiation concrete obtained in the invention has the advantages of good anti-segregation and anti-radiation performances, effective improvement of the construction performances of concrete, high mechanical strength, and effective prolongation of the service life of concrete buildings.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a radiation-proof concrete and a preparation method thereof. Background technique [0002] Nuclear technology has developed rapidly since its birth, and has been widely used in many fields such as nuclear power, education, scientific research, and medical treatment. However, its safety has always been the key to its further development. As we all know, a large number of α, β, γ rays and neutron rays produced by nuclear reactions can induce cancer, leukemia, multiple myeloid cancer, large breast malignant tumors, thyroid dysfunction and other human terminal diseases, as well as induce plant gene mutations and harm The growth of crops, and its long incubation period, cannot be known in a short time. Therefore, in order to prevent radiation from harming the human body, protective bodies must be installed when building buildings with radiation sourc...
