Clinker Substitutes : GCCA

Clinker Substitutes. A range of materials – often industrial byproducts that would otherwise be waste – can be added to cement to reduce its carbon footprint and support the circular economy. Clinker substitutes – or supplementary cementitious materials (SCMs) – are a wide range of both naturally-occurring and industrial byproduct ...

Clinker

Clinker. Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 is released (also known as process emissions). A substantial amount of heat is needed to start and sustain the chemical ...

Cement Production

The cement production process is one of the most energy-consuming processes and has a strong environmental impact. The main impact on the energy consumption of cement production is the burning process of cement clinker in a rotary kiln, and the energy costs associated with burning cement clinker constitute 50-75% of cement production costs.

How Cement is Made

The kiln phase is the principal stage of the cement production process. Here, clinker is produced from the raw mix through a series of chemical reactions between calcium and silicon dioxide compounds. Though the process is complex, the events of the clinker production can be written in the following sequence: Evaporation of free water.

Better and cheaper cement: Optimising the right clinker …

Neil Taylor of Intec Services presents the second article in his series on better and cheaper cement, this time looking at clinker quality. Kiln operation is basically about making clinker reactive enough to produce competitive quality cement. Operating the kiln at the highest sustainable output with low energy consumption will also reduce ...

U.S. Cement Industry Carbon Intensities (2019)

clinker and cement were calculated for each plant by dividing total annual CO 2 emissions from the kiln by the plant's total annual production of clinker or cement. A distribution of plant carbon intensities was created, and the intensity levels for the 25th, 50th, and 75th percentiles were calculated.

Cement Clinker

The use of SSA as raw feed for cement clinker production has been explored at rather low contents, ranging from 1% to 11%, and as is evident from the experimental blends in Table 5.2, the material has been incorporated with a range of other secondary materials such as fly ash, copper slag, ferrate waste, water purification sludge ash (WPSA) and ...
