But few people actually understand what gives concrete its strength, resistance, and utility. The aim of this course is to offer basic cement chemistry to practitioners, as well as new students in the fields of chemistry and engineering. You will learn how cement is made and hydrated, as well as the environmental and economical benefits it offers.
The characterisation of cement paste microstructure is an important step towards understanding durability mechanisms in cementitious materials. Scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) is a widely used technique to analyse the microstructure at the micron-scale. However, it is challenging, …
Cement Chemistry and Sustainable Cementitious Materials Every day, we see concrete used all around us – to build our houses, offices, schools, bridges, and infrastructure. But few people actually understand what gives concrete its strength, resistance, and utility.
1. Introduction. Cement clinker is the glue that makes up the strength of concrete. Production of cement clinker is associated with a relatively high carbon footprint (e.g., approximately 0.875 kg CO 2 /kg cement clinker [1]).. One way to reduce the carbon footprint of cement clinkers is to use alternative fuel and raw materials [2], [3].Because …
This course will teach you the basic cement chemistry. You will learn how cement is made and hydrated with its environmental and economic benefits. You'll learn to test samples in isocalorimetry in order to track …
SEM analysis of changes in the morphology and microstructure of cement pastes allow to track the hydration progress observed mainly by changes in the C–S–H phase. The initial stages of hydration of this phase is characterized by radial concentration of fibers or needles, often narrowed at the ends. This fibers grow from the surface of the ...
A low water/cement ratio (w/c=0.20) hydrated Portland cement paste was analyzed by grid-indentation coupled with ex situ scanning electron microscope-energy-dispersive X-ray spectra (SEM-EDS) analysis at each indentation point.Because finite element and Monte-Carlo simulations showed that the microvolumes probed by each …

Pore structure. 1. Introduction. As indicated in the title, this paper is an attempt to provide a `visual primer' illustrating the important features of hydrated cement paste (hcp), both in separate preparations and in concrete, as seen in backscatter-mode scanning electron microscopy (SEM). The approach employed is purely qualitative.

The results showed significant incorporation of aluminum (Al) into the C–S–H gel and other minor elements, with a presumable composition close to that of aluminum-tobermorite. The C–S–H composition of the FABC-2-W is more stable over the hydration time than that of the FABC-2-N cement. Portlandite is scarcely formed during hydration.
