KIMA Echtzeitsysteme (Germany) decided almost 20 years back to develop the fill-level measurement called SmartFillTM which is based on structure born sound. The highly reproducible and stabile signals which give the filling of chamber 1 and chamber 2 in a 2 comp...
A new class of isochemical hydraulic binders, based on the formation of hydraulic active calciumhydrosilicates (hCHS), offers a new approach to the production of pure C-S-H hydraulic binders. This development is based on results from fundamental research on the ...
Calcium silicate hydrate (C-S-H) is the binder in concrete, the most utilized synthetic material in the world. The main weakness of concrete is the lack of elasticity and poor flexural strength considerably limiting its potential making reinforcing steel constru...

In 2017 9.19 Mt of cement and 6.33 Mt of clinker were produced by enterprizes — members of Ukrcement Association, which is 2.6% more and 2.3% less than in 2016, respectively. In 2017 the country exported 14.8 kt of clinker and 270.5 kt of cement; 1,027 kt of cli...
The content of air entrained in cement-sand mortar mix and the size of air bubbles are determined by the competition between molecules of air-entraining and plasticizing agents during their sorption on grains of cement and mineral additives and at the liquid-air interfa...
The possibility of obtaining cement clinkers with partial replacement of natural raw materials and corrective additives with coal mining wastes, tephroite basalt and lead slags is established. The introduction of the two latter components in the raw meal will allow to c...
This paper presents a hydraulically active binder that is a sustainable and environmentally responsible alternative to Portland cement. In addition it addresses the problems of transferring an innovation into adopted best practice and presents possible solutions. The pa...
