Behavior of Basalt Fibers in an Alkaline Environment

Abstract

The article presents experimental studies of the composite binders modification with basalt fibers waste. The introductory part provides studies overview of basalt fibers resistance in various aggressive environments. It was revealed that the most aggressive environment in relation to basalt fibers and other products based on them is alkaline. Also, it is promising to use their production waste as a modifying additive for building compositions. But in this case, the problems associated with leaching are equally relevant for each of the reinforcing components. The components characteristics and the test procedure are described and illustrated in the next section. The following are the results of determining the strength characteristics of samples obtained on a composite binder modified with basalt fibers and acid ash productions waste. Finally, a brief analysis and conclusions are presented to confirm the effectiveness of reducing the environment aggressiveness in relation to the basalt fibers production waste adding acidic ash to the composition.
