Portland cement, a mixture of limestone and clay that is heated and ground to produce a multiphase clinker that was first used in the early 19th century. Both Roman and Portland cement-based materials were initially engineered through gradual empiri-cal improvements due to the material's complexity and sensitivity to composition and environment.

This paper presents a new insight into the autolytic mineral self-healing method for cementitious materials. The clinker/PVP (polyvinyl pyrrolidone) autolytic microsphere was prepared via the film coating method with cement clinker as a healing agent and PVP as the autolytic coating film. The morphology and chemical structure of the microsphere were characterized by environmental scanning ...
ing clinker is ground to a fine powder to produce a cement that consists of about 50% tricalcium and 25% dicalcium silicates (also present are about 10% tricalcium aluminate and 10% calcium aluminoferrite).

After cooling, the clinker can be stored in the clinker dome, silos, bins, or outside in storage piles. The material handling equipment used to transport clinker from the clinker coolers to storage and then to the finish mill is similar to that used to transport raw materials (e.g. belt conveyors, deep bucket conveyors, and bucket elevators).
The production of cement requires considerable material input to burn clinker, which is mixed with certain additives to form the final product: cement (figure 1). Cement has become an indispensable material in the construction of buildings and infrastructure elements (bridges, tunnels, dams, sewers, power plants etc.).
September 03, 2019. by GCP Applied Technologies. One approach to reducing carbon footprint is to use supplementary cementitious materials (SCMs) to lower the clinker factor of cement. Each 1% drop in clinker factor can reduce emitted CO 2 by 8-9 kg/cement tonne. However, increasing the SCM level to lower the clinker factor usually results in ...
Secil Lobito's new Clinker and Cement Plant aims to produce and subsequently commercialize portland cement, according to international specifications. The new plant will be built according to the Best Available Technologies (BAT) defined for the cement industry, which include the adoption of pre-calcining technology in the clinker
Clinker is produced by sintering limestone (calcium carbonate) and clay (alumino-silicate) at elevated temperatures. The production of clinker involves the feeding of the raw meal into the kiln, where first the calcination of calcium carbonate takes place and then the resulting calcium oxide is burned at high temperatures together with silica, alumina and ferrous oxide to form clinker.
Continuous level measurement for cement clinker coolers. In cement production, the heart of the system is the rotary kiln, and the corresponding cooling system that follows. The efficient operation of these two systems together is critical to maintain efficiency and profitability in the cement …

Cement Clinker. Portland Cement. 1. Clinker is a nodular material which is used as the binder in cement products. Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. 2. Clinker is a granular substance containing spherical pellets of diameter 3-25 mm.
Clinker size and cement grinding. Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality. Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.

To do so: Place approximately 10mg of ground clinker in a clean depression of a white ceramic tile. Add two drops of solution A (0.25g of 2,2'-bipyridyl dissolved in 90ml of water and 10ml of concentrated hydrochloric acid). If a pink color develops within two minutes, Fe2+ is present and the clinker is strongly reduced.
