Today, very few materials are available for the protection of high-rise buildings and large constructions against blast and impact and practically, they belong to a new class of concrete, the Ultra High Performance Fiber Reinforced Concretes (UHPFRCs). UHPFRC exhibits high compressive and flexural strengths, along with high energy absorption capacity; however, it suffers from limited fire resistance, a property of critical importance as blast events are usually accompanied by fires. On the other hand, the traditional fire-resistant construction materials are practically unable to protect the structures against explosions, which is also critical, since fires in constructions are often accompanied by blast events. The present paper deals with a novel Hybrid Laminate Material (HLM), which is designed, developed and validated in the frame of an extended research, focused on the elimination of the above-mentioned risks. HLM consists of an outer layer of an optimized impact/blast-resistant UHPFRC and a superficial inner layer of a fire-resistant geopolymeric concrete (FRGC). Particularly, FRGC is based on the valorization of industrial wastes and by-products, in order to decrease the production cost and enhance sustainability and circular economy principles for the new HLM, in addition to the environmental and economic benefits of the geopolymerization technology. In this paper, the design of the novel HLM construction material is presented and the results of exploratory tests on the applicability of selected industrial waste and by-products for the FRGC development are given and the thermomechanical performance of the FRGC prepared by selected waste materials is discussed. According to the results, the fire-resistant layer of HLM can be based on waste materials providing the final product with viability and sustainability, without falling short of the properties required for such material.
