Gypsum free cements and concretes made with them: strength determination using nondestructive testing methods

Popis výsledku v původním jazyce

Gypsum free cement (GFC) is based on Portland clinker. Gypsum as an initial setting time regulation additive is replaced by a system based on lignosulfonane of alkali metal and carbonate of alkali metal. This binder features high initial strength and short initial setting time; subsequently, these properties continue in concretes made with this binding material. Concrete with gypsum-free cement is characterized with short setting time and high initial strength. Concrete with gypsum-free cement has comparable strength after 3 days of curing with a 28 days strength of common concrete with Portland cement containing gypsum. Our paper describes methodology and calibration relations for both - GFC strength determination through ultrasonic pulse velocity andstrength determination of types of concrete made with GFC using ball thrust hardness test. The last-named method is applicable for GFC compression strength determination; and also for types concrete based on GFC, commendable are impact h
