Mechanical properties of mortars based on roman cement with the addition of power plant fly ash

Popis výsledku v původním jazyce

Roman cement is a historic hydraulic binder, prepared by burning of limestone with high proportion of clay minerals, usually at temperatures below the sintering point. The burning temperatures of Roman cements range from 800 to 1200oC. At present, this binder is considered to be a promising material with a low carbon footprint and a long lifetime. The properties of Roman cement are influenced by many factors, especially raw materials composition and burning conditions. On the other hand, a disadvantage of mortars based on Roman cement is a slow increase of initial strength. In this paper, the influence of fly ash on the development of initial strength increase was experimentally investigated. The characteristics of mortars with admixtures were compared with those. The Roman cement was used as a binder. Based on the results of the experiment it can be stated that mortars with the admixture of power plant fly ash show more rapid increase of initial strengths than the reference mixture.
