The world average clinker/cement ratio is about, with the balance comprising gypsum and additives such as blast furnace slag, fly ash, and natural pozzolana. As clinker production is the most energyintensive and CO 2emitting step of the cementmaking process, reductions in the clinker/cement ratio (through use of clinker substitutes
Clinker can be blended with a range of alternative materials, including pozzolans, finely ground limestone and waste materials or industrial byproducts. The clinkertocement ratio (percentage of clinker compared to other nonclinker components) has an impact on the properties of cement so standards determine the type and proportion of alternative main constituents that can be used.
The world average clinker/cement ratio is about, with the balance comprising gypsum and additives such as blast furnace slag, fly ash, and natural pozzolana. As clinker production is the most energyintensive and CO 2emitting step of the cementmaking process, reductions in the clinker/cement ratio (through use of clinker substitutes) reduce energy use and process CO 2 possible way
Clinker substitute (slag, natural pozzolans, synthetic Large amounts of electricity are used grinding the raw materials and finished cement. Get help online
Natural pozzolans Some burnt shales also show pozzolanic reactivity. Because the pozzolanic reaction is subsequent to the initial hydraulic reaction of Portland cement, the setting times of concretes containing pozzolanic materials is often slower, and the early age strength, lower, than for concrete made with hydraulic binders (although this is not always the case, silica fume and

Fly Ash, Slag, Silica Fume, and Natural Pozzolans Fly ash, ground granulated blastfurnace slag, silica fume, and natural pozzolans, such as calcined shale, calcined clay or metakaolin, are materials that, when used in conjunction with portland or blended cement, contribute to the properties of the hardened concrete through hydraulic or
Clinker substitute (slag, natural pozzolans, synthetic Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950#176;C is the main energy consuming process. Portland cement, the most widely used cement type, contains 95% cement clinker.
