Low Energy Consuming Modified Composite Cements and their Properties

 It has been shown that in the conditions of aggravation of ecological problems, shortage of high-quality raw materials for the production of Portland cement clinker a promising direction of cement industry development is more extensive waste utilization as well as production of low energy consuming cement clinker and modified composite cements, characterized by high content of active mineral additives.

Pozzolanic Activity Diagnostics of Fly Ash for Portland Cement

The work deals with the analysis and evaluation of different methods of pozzolanic activity determination in order to rationally use ash in cement. The most optimum diagnostic method has been suggested. The possibility of increasing fluidal fly ash activity has been established using the synthetic nanosilica.
