The formation of self-compacting basalt fiber concrete based on a composite binder

This article presents the results of experimental studies aimed at determining the laws of structure formation of a composite binder for self-compacting basalt fiber concrete. The conducted scientific research revealed that after mixing the composite binder – consisting of Portland cement, zeolitic rock, and quartz sand – with water, the process of structure formation slightly slows down at the initial stage; however, subsequently, the formation of new hydration products accelerates sharply. In addition, it was shown that the induction period of setting of the cement–composite mixture increases with a decrease in the clinker component content in the composite binder. At the same time, it was established that the activity of the cement-composite stone and the basalt fiber concrete based on it persists for a long time at various ages, including early ages, and that their structure intensively gains strength.
