Switching from Blaine measurements to laser diffraction particle size analysis

Increasingly the cement industry is adopting laser diffraction particle size analysis. Unlike Blaine analysis, laser diffraction delivers a size distribution for the sample, rather than a single averaged figure. This makes it the more sensitive technique for characteriz...

SNiPs or Eurocodes

In the article the issue of applicability and relevance of use of foreign standards in the domestic practice of construction, engineering and construction materials production is raised. Trends and possible consequences of mandatory introduction of European standards ar...

Comparison between NMR non destructive method and common invasive methods used for cementitious material structuration evolution

A better understanding of the cement hydration evolution and of the development of cementitious materials microstructure at early age is very important for improving concrete durability. The microstructure, which depends on various factors (water-cement ratio, curin...

Cement hydration and microstructure of concrete

The article presents the results of a study of cement hydration, using ESEM electronic microscopy, quantitative X-ray phase analysis and other experimental methods, and a qualitative pattern of hydration developed from experimental data.

Raising activity of cement after long time storage by adding electrolytes

It was established that the addition of 1% of the electrolytes with highly charged cations and anions (Fe2(SO4)3, Al2(SO4)3) helps to increase the activity of Portland cement stored for 23 months in an unheated room. In this case, the compres...
