The investigation into the phase composition of products in the fly-ash cenospheres - cement matrix system
The phases formed during the process of hardening of fly-ash cenospheres-cement matrix system have been established. The analysis of the products’ formation in 1,3 and 90 days age and the results the specimens’ compressive strength testing of fly-ash cenospheres-cement paste specimens allow to infer, that fly-ash cenospheres possess pozzolanic activity.
