Abstract
Polymer-cement composites (PCCs) are materials in which the polymer and mineral binder create an interpenetrating network and co-operate, significantly improving the performance of the material. On the other hand, the need for the utilization of waste materials is a demand of sustainable construction. Various mineral powders, such as fly ash or blast-furnace slag, are successfully used for the production of cement and concrete. This paper deals with the use of perlite powder, which is a burdensome waste from the process of thermal expansion of the raw perlite, as a component of PCCs. The results of the testing of the mechanical properties of the composite and some microscopic observations are presented, indicating that there is a possibility to rationally and efficiently utilize waste perlite powder as a component of the PCC. This would lead to creating a new type of building material that successfully meets the requirements of sustainable construction.
Highlights
The utilization of the waste materials for the production of building composites is required for sustainable development in construction [1]; results of the Life Cycle Analysis proved the effectiveness of this kind of solutions [2,3]
Perlite powder is a burdensome are successfully used for the production of cement and concrete
The test results show that perlite powder for the manufacture of polymer-cement composites (PCCs) is presented
Summary
The utilization of the waste materials for the production of building composites is required for sustainable development in construction [1]; results of the Life Cycle Analysis proved the effectiveness of this kind of solutions [2,3]. The subject of this paper is evaluation of the possibility of use of waste perlite powder as a component of polymer-cement composites (PCCs). Ramezanianpour et al [19] and Vosoughi et al [20] have studied the possibility of partial substitution of cement by expanded perlite powder during concrete production. Jaworska et al recently pointed out the possibility of using waste perlite powder as a PCC component and evaluated the chemical resistance of such composites [29]. The influence of perlite powder on the mechanical properties of PCCs is presented, and the utilization of this burdensome waste as a partial substitute for cement in PCCs is discussed
