This article examines the problem of the service life of reinforced concrete structures intended for nuclear power plants and radiation waste storage bunkers when exposed to radiation. This research focused on assessing the corrosion resistance of steel bars under conditions of simultaneous exposure to gamma radiation and various environmental conditions affecting the rate of carbonation. Electrochemical measurements of steel bars were carried out on samples in three environmental conditions: in a laboratory–dry; enclosed in a can at RH = 50%; and enclosed in a can at RH = 100%. The durability of the passivation layer of steel on non-irradiated and irradiated specimens after 8 months of exposure to gamma radiation was compared. A lower degradation effect of gamma radiation was visible in fully water-saturated specimens.

: Nowadays, most industrial solid waste, agriculture waste, and natural minerals are piled up, which not only occupies land resources, but also has a dangerous impact on the environment. The responsible management and recycling of these materials can have significant environmental benefits, while also providing a means of accessing raw materials for the creation of geopolymers. Geopolymers are new, environment-friendly, cementless materials and alternative construction materials to ordinary Portland cement. They not only have excellent mechanical properties, but also have valuable properties, e.g., high-temperature resistance. This paper summarizes the feasibility studies in terms of base materials and properties of today’s developing geopolymers. This paper also highlights the significance of developing sustainable materials for civil engineering.

: The design of sustainable construction materials is continuously gaining increasing importance in civil engineering. Geopolymers are attractive alternatives to cementitious materials in terms of environmental impact and specific material properties, such as durability, an initial increase in mechanical properties, or chemical and thermal resistance. Such favorable properties can be advantageously utilized within various applications involving the design of materials for heavily stressed industrial floors. The research presented in the paper was focused on the design of a geopolymer composite based on metashale MEFISTO L05 and waste metashale RON D460HR binders. The 1:4 raw/waste mix of binders activated by potassium hydroxide/silicate was supplemented by 0.11 wt.% of graphite fibers to optimize electrical properties and bestow on it some new material functions, such as self-heating. The further utilization of fine waste aggregate (crushed defective concrete products, waste concrete from auto-mixers) resulted in an ~85% utilization of input waste materials. An acceptable mechanical performance of the mortar for particular civil engineering applications was observed (28d: R f ~ 2.5 MPa, R c ~ 15 MPa), as well as favorable thermal and DC/AC electrical properties, predicting the self-heating potential.
可持续建筑材料的设计在土木工程中越来越重要。地聚合物在环境影响和特定材料性能方面是胶凝材料的有吸引力的替代品，例如耐久性，机械性能的初始增加，或化学和耐热性。这种有利的特性可以在涉及重应力工业地坪材料设计的各种应用中得到有利的利用。本文主要研究了以MEFISTO L05和废MEFISTO RON D460HR为粘结剂的地聚合物复合材料的设计。在以氢氧化钾/硅酸盐为活化剂的1:4料废混合料中添加0.11 wt.%的石墨纤维，使其电性能得到优化，并赋予其自加热等新材料功能。进一步利用细骨料(破碎的缺陷混凝土制品、自动搅拌机的废混凝土)，使投入废料的利用率达到85%。在特定的土木工程应用中，观察到砂浆的可接受的机械性能(28d: R f ~ 2.5 MPa, R c ~ 15 MPa)，以及良好的热学和直流/交流电学性能，预测了自热潜力。

: Cement production has the largest carbon-footprint since it leads to the release of carbon dioxide and enormous energy consumption. Therefore, scientific research is being conducted world-wide on the possibility of using other materials that can be used as a cement substitute. A potential alternative material is glass powder. This paper present research results on the use of glass powder as a partial cement replacement with a substitution level of 0–20%. The pozzolanic activity and the influence of glass powder on cement hydration were analyzed. The porosity, the microstructure of the interfacial transition zone and the compressive strength of mortar were also investigated.

: A multispecies model for chloride migration in cementitious materials was proposed. The model is applied to simulate chloride migration in the concrete submitted to the chloride migration test, considering the electrode processes. These processes are very rarely integrated into the literature, despite their impact on the chloride migration and the electroneutrality in the pore solution of the material. The generation of OH − in the cathode and H + in the anode allows for the monitoring of the electroneutrality. The modelling considers all the ions of the pore solution. Ion fluxes are calculated using Nernst–Planck equation. The Langmuir model is used to simulate the chloride isotherms. The thermodynamic equilibrium in the material is considered, which reflects the liquid– solid interactions during the migration. The ion profiles with and without considering the electrode processes are presented.
