Cement - Wikipedia

02.10.2001 · A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is only behind .

Cement - History of cement | Britannica

Cement - Cement - History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of 2,000 years ago and of subsequent construction work in western Europe.

The Development of Portland Cement

While most lime mortar mixes revolved around 1:1 through to 1:3, cement mortars could be mixed with aggregate to a wider range of proportions. Early experiments carried out on cement showed that a mix of 1:1 was approximately 3.4 of the strength of neat cement and .

Test temperatures ranged from 27 to 871°C. Cement paste contracted when subjected to temperatures from 204 to 871°C. Thermal expansion of mortar and concrete was dominated by thermal expansion characteristics of the mineral aggregate. However, expansion was moderated by contraction of the cement paste matrix at elevated temperatures.

Consequently, the Sc development of the cement mortar with GBS replacement was better than that of the mortar without GBS (Ahmed and Buenfeld, 1997). In addition, the Sc of T-II mortar was higher than that of D-III mortar and approached that of D-IV mortar (Fig. 2A, B). A possible explanation for this is that GBS produced a large number of ...
