High performance cement and production process

Abstract

This invention is related to the production of High Performance Cement (HPC) where the clinker (being the raw material for ordinary Portland cement (OPC) which is the major material in the construction industry), is ground through a special grinding technology (regarding conformity to the designated principles during grinding, like; regime temperature, humidity, grinding duration) by adding a modifier (complex chemical composition) for improving mechanical-chemical properties of the cement particles, resulting production of high performance cements such as HPC 62.5 with better properties than the known cements in the standards. The invention is also related to the use of same technology to improve the performance and quality of the composite cement types with reduced clinker content for replacement of other additions such as; slag, limestone, sand, fly ash, trass (pozzolan) etc.; The invention also defines the production process and production units of the high performance cement.

Description

technical field [0001] The present invention relates to the production of High Performance Cement (HPC) in which clinker is used as the raw material of Ordinary Portland Cement (OPC) which is the main material in the construction industry, by special grinding technology (regarding the degree of compliance with specific conditions when grinding, such as temperature conditions, Humidity, grinding time) grinding and adding modifiers (complex chemical composition), so that the mechanochemical properties of the produced cement particles can be improved. The present invention also involves using the same technology to improve the performance and quality of all blended cement types other than pure Portland cement. In addition to the use of modifiers, the present invention also defines the production method and production components of high performance cement (HPC). Background technique [0002] For more than a hundred years, the production of cement for the construction industry h...

Problems solved by technology

[0011] Since the cement produced by the existing technology does not directly provide the required high strength, high workability and low water and cement ratio for concrete, it becomes difficult to produce high-strength concrete, resulting in insufficient strength, resulting in unsatisfactory appearance of high concrete structures. Concrete Parts Saved

[0012] The required economic life of concrete is not long enough due to insufficient durability and / or strength qualities of concrete to withstand multiple environmental factors
