Opis:
This work is a continuation of the authors' research conducted to develop innovative concrete mixtures containing recycled ceramic aggregates formed after crushing of waste ceramic sanitary elements. The article presents the problem of utilization of ceramic waste, there are listed factors of waste generating and the main characteristics of the waste material. Based on available literature, there are presented the results of research work on successfully using ceramic waste aggregates in the production of concrete composites. The main aim of this work was to design innovative concrete containing sanitary waste which would be permeable to water. The composite presented in the work showed total water permeability. The tested strength parameters allowed us to propose using it for the communication substrates carrying the load from pedestrian traffic. In this type of communication substrates the authors see a remedy for the problem of utilizing rainwater. Especially in urban areas where is no rain water sewer system this solution would have a legitimate benefit. Totally permeable communication routes could directly transfer water to the substrate under their surface which would effectively increase the chance of natural rainwater absorption.

Opis:
Modern dynamically developing building industry poses more and more complex challenges to building materials. Elevated constructions must satisfy a number of requirements including safety, durability and being environmentally friendly. The unfavorable impact of increased temperatures on the work of a construction structure is manifested by the change in the properties of the heated material and the occurrence of deformation, stresses and thermal scratches. These are particularly dangerous phenomena when they occur in elements with limited freedom of linear deformation. The purpose of the research presented in this article was to find a solution for concrete that is both resistant to spalling and characterized by high strength properties after heating. The main thesis put forward by the authors of the article is the assumption that deliberate concrete aeration will allow the introduction of evenly distributed micro air bubbles into its volume, which will constitute a reservoir for increasing the volume of water converting into water vapor as a result of a sudden increase in temperature. The presented schema enabled the assumption that the strength parameters of aerated concrete would decrease slightly in relation to non-aerated concrete, however it would be still possible to use in reinforced concrete constructions. As can be seen from the aforementioned analyzes, aeration modification can be an effective means of designing high temperature resistant concrete.
