摘要：The effectiveness of coatings based on Portland cement and sodium silicate with graphite filler as an electrocorrosion protection of grounded screens is investigated. An original technique is developed, consisting in comparing the values of the current I through the reinforcement and concrete of the structure model without protection and with protection by grounded screens-coatings. As a result of experimental studies it is found that, in comparison with the model without protection, the I value of the coated model of the Portland cement-based composition is less: by 49-66%, and for the model coated by sodium silicate-based composition - by 34-60%.
