Annular large-volume anti-radiation barite concrete and preparation method thereof
The invention relates to the technical field of concrete processing, and particularly discloses annular large-volume anti-radiation barite concrete and a preparation method thereof. The barite concrete is prepared from the following raw materials in parts by weight: 140 to 180 parts of water, 215 to 265 parts of cement, 37 to 45 parts of fly ash, 55 to 65 parts of slag powder, 1200 to 1400 parts of heavy crystal sand, 1400 to 1700 parts of barite, 7.5 to 9 parts of a water reducing agent, 16 to 20 parts of a calcium sulphoaluminate type expanding agent, 10 to 14 parts of a magnesium oxide type expanding agent and 4.5 to 5.5 parts of a retarder. According to the barite concrete, through the synergistic effect of the raw materials, the crack resistance, the compressive strength and the breaking strength of the barite concrete are improved, the settlement phenomenon of the barite concrete is improved, and the market requirement is met.
