AbstractAbout AuthorsReferences
Nowadays, numerous studies have proven that slag-alkaline systems: cements and concretes are promising materials that compete with ordinary cement concretes in the construction industry. This is justified by a wide list of their competitive properties that meet modern requirements for building materials and products. However, despite the positive aspects of this group of materials, they are characterized by significant drawbacks that limit their wider practical application, including shrinkage during hardening. Within the framework of the article, the influence of the gypsum-containing component – citrogypsum, on the character and kinetics of shrinkage deformations of slag cements of various component compositions during the hardening process was studied. It was found that, depending on the type of alkaline activator, the addition of citrogypsum had a different effect on the shrinkage values of the binding system. When the NaOH binding system is activated, the introduction of citrogypsum helps to reduce shrinkage deformations up to two times. When using Na2CO3 and Na2SiO3 salts as alkaline activators, the addition of citrogypsum contributes to a sharp increase in shrinkage from 5 to 10 times.
