AbstractAbout AuthorsReferences
An issue of improving the vibro- and earthquake resistance of brick masonries with the use of nano-technologies is considered. It is proposed to use methods which don’t require significant capital expenditures. The efficiency of using self-compacting cement mixes obtained with the help of superplasticizers – polycarboxylates, molecules of which are nano-particles, is shown. The use of the sol-gel method when preparing brickwork mortars, modification of cement polyvinyl acetate mortars with esters of orthosilicic acid is very effective. A method for protection of silicate brick against destruction during the fire with the help of intumescent paints, which contain fullerene-like nano-particles – fulleroids, is proposed. Introduction of basalt microfiber in the form of fibers with a nano-modifier fixed on them in cement mixes efficiently affects the strength of masonry mortar.
