Preparation and characterization of Portland cement clinker …
The content of C 3 S in ordinary Portland cement ranges typically from 55% to 65% [28, 29]. Normally, C 3 S formation is effectively complete at a sintering temperature of about 1450 °C . Therefore, the optimum sintering temperature for the preparation of Portland cement clinker from acid leaching residue was 1450 °C.
Microwave-promoted burning of Portland cement clinker
1. Introduction. The application of microwave to ceramics sintering began in the mid-1970s. The first experiment attempt of microwave burning cement clinker was reported by Quéméneur et al. [1], [2].After that, Fang et al. and Li et al. [3], [4], [5] reported microwave clinkering of ordinary and colored Portland cement and C 3 S, and so on. …

Product Name: Portland Cement Clinker 1.2. Intended Use of the Product Cement clinker is produced by heating to high temperature a mixture of substances such as limestone and shale. When cement clinker is ground with a specified amount of gypsum, it will produce Portland cement or when ground with specified amounts of
Beyond Portland cement: Low-carbon alternatives
A combination of calcined clay and limestone can directly replace a high proportion of Portland clinker in cement. This is known as Limestone Calcined Clay Cement, or LC3. In European standards, ternary blends such as CEM IIB-M(Q-LL) already allow for a clinker content of just 65%, with calcined clays (Q) and limestone (LL) making up the rest.

The ternary system Portland cement–calcium sulphoaluminate clinker
Binders composed of ordinary Portland cement (OPC), calcium sulphoaluminate clinker (CSA) and anhydrite (C S ¯) were examined in order to study the impact of variations of the OPC:CSA: C S ¯ ratio on the hydration process and related mortar properties.A first sample series had various anhydrite contents and fixed OPC to …
Definition of portland cement
A. Portland cement is the product obtained by pulverizing clinker, consisting of hydraulic calcium silicates to which some calcium sulfate has usually been provided as an interground addition. When first made and used in the early 19th century in England, it was termed portland cement because its hydration product resembled a building stone ...
