1. Introduction
Concrete is a versatile and the most widely spread construction material not only for general use, but also for restoration/reconstruction of historical concrete buildings and for so-called “responsible” structures like tunnels etc. In case of fire a concrete can be heated to temperatures of brittle fracture of concrete (653 K) during the first 10 min and reinforcement to temperatures of plastic deformation (773 K) during the next 50 min resulting in quick loss of integrity and load-bearing ability of the whole concrete structure. That is why a regular practice in the EU countries is to develop fire protection measures for each “responsible” application with consideration of various fire scenarios [1–5]. From the point of view of physico-chemical views on the processes of destruction under action of high temperatures (dehydration) of cement stone hydration products, these processes are accompanied by vapor mass transfer associated with crack opening and occurrence of so-called autogenous stresses. As a result, integrity of concrete lining is lost due to explosion. In order to eliminate negative effect of fire on structural elements of concrete structures the passive fire protection measures should be used, among them the application of fire and heat resistant materials based on mineral binders [13], inclusive of geopolymers [6–12]. More advantageous is the application of intumescent coatings based on organic and mineral binders as active protection
