This work aimed to investigate the influence of selected material variables on the self-cleaning and air purification efficiency in NOx pollutants of cement-based photocatalytic composites. Tests were performed on cement mortars, with seven independent variables considered: the mass ratio between cement and quartz powder to sand, the water to cemen...
The application of photocatalytic materials has been intensively researched in recent decades. The process of nitric oxide (NO) oxidation during photocatalysis has been observed to result in the formation of nitric dioxide (NO2). This is a significant factor of the photocatalysis process, as NO2 is more toxic than NO. However, it has been reported...
The article presents an in-depth analysis of the mechanism leading to protective coating failure and concrete corrosion in the wastewater treatment plant. Losses of protective epoxy coatings over large areas and deep concrete deteriorations with a maximum depth exceeding 2 cm were found after just 2 years of service on the concrete elements of pre-...
The main assumption of eco-efficient High-Performance Concrete (HPC) design is the reduction of Portland cement clinker content without negatively affecting the composite’s mechanical and durability properties. In this paper, three low-clinker HPC mixtures incorporating slag cement (CEM III/B as per EN 197-1) and Supplementary Cementitious Material...
This paper presents the results of laboratory tests on photocatalytic pavement blocks from a bicycle lane in Poland after seven years of service. Air purification performance was tested on dusty and clean samples using different light sources and setups, with non-laminar gas circulation. Secondary Electrons Secondary Ions (SESI) and InLens detector...
The paper presents the use of photocatalytic concrete in the context of reducing the concentration of nitrogen oxides in the air. Themechanismof the photocatalysis process and research methods on the effectiveness of this solution are described. Examples of realizations using photocatalytic concrete and factors influencing the effectiveness of redu...
In this paper the effect of limestone and granite aggregate on drying shrinkage of a concrete is investigated. Mixes containing limestone and granite with different Dmax and cement paste volume were tested. A two level, full factorial experiment with three independent factors was conducted which allowed not only to determine the influence of every...
Analysis of the possibility of using CaO as an alkaline activator of GGBS for producing low-price and durable binder
