STATUS AND PROSPECTS OF RESEARCH AND APPLICATION OF ALKALI-ACTIVATED MATERIALS PAVEL KRIVENKO V.D.Glukhovsky Scientific Research Institute for Binders and Materials, Kiev National University of Civil Engineering and Architecture 31 Vozdukhoflotsky prospect Kiev 03037 Ukraine e-mail: pavlo.kryvenko@gmail.com Introduction Beginning from 1957, a scientific school in Kiev (USSR) headed by Victor Glukhovsky has been developing a new direction in binding/cementitious/ materials.
Cement type Early strength Durability Chemical resistance Portland cement ++ ++ + Blended cement + +++ ++ High alumina cement +++ + +++ High sulphate cement + ++ +++ Alkali-activated cement +++ +++ +++ Sulphoaluminate cement +++ ++ +++ 7 Industrial uses The experience from the small- and large scale industrial uses of the alkali- activated cements gained starting the 1960s in construction (hydropower engineering, road, agricultural, industrial, civil engineering, mining, etc.) gave proofs to high performance properties of the concretes on them.

The samples were tested in the laboratory of Civil Engineering faculty of Kryvyi Rih National University, Ukraine.
The deformations of the stretched and compressed concrete fibers at the height of the section were determined with the help of engineer’s dial gauge with a price of 0.01 mm readability.
