Description
Technical Field
The invention relates to the technical field of concrete, in particular to gamma-ray-resistant ultra-high performance concrete and a preparation method thereof.
Background
The search for the radiation-proof engineering material with excellent cost performance is always a dream of engineers in the field of nuclear power engineering and national nuclear protection engineering. In view of the fact that materials with good radiation protection performance, such as lead plates, steel materials and the like, such as wax, water, lead, boron, polyethylene and the like, are expensive in manufacturing cost, poor in engineering weather resistance, or cannot be shaped, and cannot be directly used for constructing a main structure of an engineering.
Therefore, at present, in the nuclear radiation protection structure, concrete with low cost and balanced mechanical property and durability is mainly adopted to form a reinforced concrete composite structure with reinforcing steel bars, and a three-dimensional and comprehensive nuclear radiation engineering protection and structure system is jointly constructed by taking a lead plate and a steel plate which absorb gamma radiation as auxiliary structures and materials such as water, wax, lead, boron, polyethylene and the like which absorb neutron radiation as auxiliary structures
The concrete in the prior art is prepared by mixing cement, sand, stones, water and a water reducing agent, has the advantages of higher compressive strength, easy material taking, easy forming and low price, can be combined with steel materials to prepare various bearing members, but has the fatal defects of low tensile strength, large brittleness, easy cracking and poor toughness, thereby reducing the bearing capacity of a concrete structure and shortening the service life, and the common reinforced concrete structure has large and heavy size and poor durability which is generally only 30-50 years, and has the structural diseases beginning to appear along with the increase of the service life and needs to be maintained and reinforced to maintain the service function;
secondly, because the nuclear radiation protection capability of the common reinforced concrete is not enough, an auxiliary protection structure needs to be added, the structure adopts various nuclear radiation protection materials, and the structure cannot be used as a stressed main structure but only can be used as a protection layer due to the problems of self strength and service performance. The auxiliary structure increases the process flow and the construction cost is increased.
At present, the performance of the radiation-proof concrete is improved and improved by adding minerals with heavy metal elements into the improved radiation-proof concrete at home and abroad; and researches prove that the concrete material is doped with Mg, Ti,14C、55Fe and60both Co and Cu can improve the radiation protection capability of concrete, and aggregates containing heavy metal elements such as serpentine, magnetite (hematite), limonite, iron oxide powder, barite, gypsum powder, boresite, chromium ore powder, galena and the like can be used for improving the gamma ray and neutron ray shielding capability of concrete in actual production.
For example, patent CN1314874A discloses a radiation-proof concrete and a radiation-proof housing, and specifically discloses the following: in order to achieve the greatest possible shielding effect against heat and radiation, the radiation-protective casing according to the invention has a wall area which is made of radiation-protective concrete with a first boron-containing filler having a particle size of up to 1mm and a second metal filler having a particle size of up to 7 mm. According to a first embodiment, the first boron-containing filler is present in the radiation-protective concrete in a proportion of at least 5.0% by weight, in particular at least 7.8% by weight. In a second embodiment, the proportion by weight of the second metal filler in the radiation-protective concrete is in the range between 80 and 90%, in particular between 85 and 89%. At the same time, the proportion by weight of the first boron-containing filler is in the range between 1.0 and 1.5%.
The patent CN106977145B discloses an anti-radiation concrete, which comprises, by weight, 360 parts of cement 340-.
The filler or aggregate of the patent is used for radiation protection, the aggregate has a good radiation shielding effect, but because the aggregate has high density, large concrete capacity and poor concrete construction performance, more importantly, the radiation protection concrete prepared by adopting a heavy concrete method can increase the self weight of a building and the requirement on the pile foundation of the building, and can bring adverse effects on the seismic performance of the building. Therefore, when the radiation-proof concrete is used, the final quality of the radiation-proof concrete is ensured by considering the comprehensive performance of the concrete.
