Witton Cement Group LLC Share: cement special cement free radiation: X-ray, γ-ray, neutron, and thermal neutron shielding effect can play better cement. Such major varieties of cement cement barium, strontium cement, boron-containing cement. Barium cement to clay as the main raw material barite, calcined to obtain barium silicate two main mineral composition of clinker, gypsum and then adding the right amount of ground together. Its proportion of 4.7 to 5.2 special cement, with heavy aggregate (such as barytes, steel sections, etc.) formulated as a radiation concrete. Barium cement poor thermal stability, not only suitable for the production of heat radiation protection wall. Strontium is strontium carbonate cement in place of all or part of the raw material limestone Portland cement, calcined get to tricalcium silicate strontium as the main mineral composition of clinker, adding an appropriate amount of gypsum to grind together. Its performance is similar to barium cement special cement formulation, but anti-radiation performance slightly inferior to barium cement. Adding an appropriate amount of alumina cement clinker and gypsum szaibelyite, common ground can be obtained boron-containing cement. Such boron-containing cement and aggregate, heavy aggregate can be formulated into a higher proportion of concrete for fast and thermal neutrons protective shield project. Witton Cement Group Co., Ltd. to share: the presence of the main problems of the current development of special cement two major problems: First, the lower the yield, the scale of China's national economic development are incompatible. 1995 China's cement output reached 476 million tons, but only about 6.56 million tons of special cement, accounting for 1.38% of total cement production. Japan 1989 special cement output of 500 million tons, accounting for 6.2 percent of total production of cement; special cement production in the Soviet Union in 1989 amounted to 14.6 million tons, accounting for 10.4 per cent of total production of cement; special cement production in the United States in 1980 reached 5.8 million tons , accounting for 9.0 percent of total production of cement. It is predicted that by the year 2008 China's demand for cement will reach 10 million tons. By special cement demand of 3% of its production should reach 30 million tons, this goal there is a great distance from current production. Second, the product structure of special cement itself, the development of special cement, cement decoration and expansion of self-stress roughly the same proportion of cement, oil well cement and hydraulic cement low proportion compared with the US, Japan and the Soviet Union and other countries fast hard early strength cement is a serious shortage. Such foreign cement production typically 3-8% of special cement technology, a variety of special cement in the highest yield for a class, while China accounted for only 0.06%, the lowest yield category.
