The paper considers the method of production cement based materials with the byproduct sulfur. Application of the thermoplastic additive, obtained as a hydrophilic residue of the sol-gel method, is based on the possibility of homogeneous distribution of sulfur particles in composite materials with further thermal activation of the additive. The influence of additive on physical and technical characteristics of composites when modifying the cement matrix was determined. The effectiveness and uniqueness of this additive for different binders were shown. The usage of this thermoplastic additive causes the improvement of strength, density and corrosive resistance. This technology is a wider method of cement binder and gypsum binder modification. It is based on physical and chemical interaction and it will be used for new composite designs. In addition, due to special properties of byproduct sulfur, it can be used for design of construction and building materials which are functioning in special conditions. Application of this inert modifier allows for increasing corrosive resistance of cement constructions without strength reduction.References
