Abstract
The invention discloses energy-saving and environment-friendly building cement, which is prepared from the following ingredients in parts by weight: 150 to 180 parts of limestone, 50 to 60 parts of coal ash, 8 to 10 parts of copperslag, 15 to 20 parts of kaolin, 20 to 30 parts of sandstone, 5 to 8 parts of aluminum oxide, 5 to 8 parts of wood calcium, 6 to 8 parts of iron-ore slag and 8 to 10 parts of straw. Wherein the particle size of the straw is 120-200 meshes. According to the energy-saving and environment-friendly building cement provided by the invention, the industrial waste residues are recycled, and the strength of the cement is improved.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to an energy-saving and environment-friendly building cement. Background technique [0002] With the comprehensive development of infrastructure construction in my country, the use of various building materials is increasing, and the amount of cement materials is increasing day by day. Although many raw materials used in cement production are minerals with low economic value, they are also natural non-renewable resources, and the resource reserves will gradually decrease with the increase of resource usage. The use of industrial solid waste to replace or partially replace raw materials for cement production has become a sustainable production method and can also reduce production costs. [0003] The Chinese invention patent application publication number CN110482885A discloses a Portland cementraw material formula, including the following proportions by weight: limeston...
