Abstract
The acid-resistant concrete, modified with polymers, is used in construction. It has high strength performance at the initial stages of setting and during thermal treatment as well as good processing of the mix. The acid-resistant concrete consists of the following constituents in weight percents: sodium silicate 1, sodium silicofluoride 0.14 to 0.18, mineral flour 1.2 to 1.3, quartz sand 2.5 to 3.0, and a furan additive 0.03 to 0.06. The mineral flour is quartz and the concrete contains perlite flour 10 to 30 percent of the quartz flour amount.
