Abstract

The invention relates to cement formula, in particular to an energy-saving environment-friendly cement formula. The energy-saving environment-friendly cement formula comprises the following componentsin parts by weight: 25 to 40 parts of cement clinker, 15 to 25 parts of a limestone powder, 8 to 15 parts of pan bottom furnace slag, 8 to 15 parts of mineral slag, 3 to 8 parts of aluminium oxide-aluminium sulphate, 8 to 12 parts of silicon dioxide, 5 to 8 parts of aluminium oxide, 3 to 6 parts of a grinding aid and 8 to 12 parts of an impervious waterproof agent. According to the energy-savingenvironment-friendly cement formula, the cement manufacturing cost is reduced by recycling and utilizing waste, such as the mineral slag and the furnace slag; the quality of the cement is ensured andthe performance of the cement is improved by adding some additives which can improve the performance of the cement; the energy-saving environment-friendly cement formula is accord with an environmental protection concept.

Description

technical field [0001] The invention relates to cement, in particular to an energy-saving and environment-friendly cement formula. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. It can be mixed with water to form a slurry. It can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. Concrete made of cement bonded gravel not only has high strength after hardening, but also can resist the erosion of fresh water or salt water. For a long time, cement, as an important cementitious material, has been widely used in civil engineering, water conservancy, national defense and other projects. [0003] my country's cement production ranks first in the world for many years in a row, but the production consumes more resources and energy, and the price paid is also relatively high. The energy consumption is 50% higher than the world's advanced level. Difficult to be in line with internat...
