Many studies have been carried out on the problems of civil engineering with the change of human problems today and in the past. These studies contributed to the development of concrete technology. Concrete is an important building material consisting of mixing aggregate, cement and water with or without chemical and mineral additives since the first day of use. Concrete technology has made great progress and continues. With developing concrete technology, self-cleaning concretes have emerged. Many studies have been conducted on self-cleaning concretes by researchers. This article reviews the research published on self-cleaning concretes and presents its role in reducing environmental pollution and its place in future engineering studies. When we look at the studies on self-cleaning concretes that emerged as a result of the developments in concrete technology, it is seen that the developments have progressed considerably. Contemporary civil engineering has provided a highly effective solution for the solution of modern problems. Environmentally friendly building materials will fulfil their duty in reducing air pollution, one of the biggest problems of our time. Self-cleaning buildings and roads that reduce pollution may sound like futuristic ideas, but it is not far away to encounter these structures more widely in our country and our world.

This study presents an introduction in air revitalisation practice by using a microalgae-based biosystem. Although the study is developed in the light of space applications, it opens new horizons for implementing such systems for terrestrial applications as well, where biotechnologies for addressing climate change and other issues associated with air pollution is in high demand. The experiments have been performed at laboratory-scale by using Arthrospira (spirulina) platensis as microalgae model. Influence of culture and illumination conditions, as well initial gas composition and other factors/techniques such culture filtration on the biosystem performance were investigated and the relevant results are presented and discussed. Based on the actual findings, future research needs are addressed.
