The Belgian standard specifications contain a number of clear requirements for the composition of concrete mixtures and the properties of fresh and hardened concrete. It is generally known that water and air content have a substantial impact on the frost susceptibility ...
The paper offers an advanced scientific and practical understanding of the sulfate corrosion affecting Portland cement concretes and examines its most important and relevant aspects: external and internal sulfate corrosion, thaumasite and delayed ettringite formation; p...
In the presence of superplasticizers the effectiveness of air-entraining additives in the concrete (the optimum dose, the level and stability of air entrainment) depends on competitive adsorption and, accordingly, is determined by the chemistry of the functional...
The influence of the material from used tires containing ZnO (as an alternative fuel), as well as the addition of zinc oxide (up to 2%) on sintering and phase composition of the clinker were examined. The burning property of the raw material mix is i...
The paper describes the influence of the oxide composition and the modular characteristics of clinker on the energy consumption during burning of Portland cement mix and grinding, the optimal degree of substitution of the clinker with pozzolanic additives (fly ash&#...
