The durability of eco-efficient, clinker reduced concrete is a key factor of its performance. In the presented study, different durability indicators of a newly developed eco-concrete composition (ECO) are tested versus standard normal concrete as referen... see more

In order to support the use of cement combination concrete in construction, this paper investigated the resistance of Portland cement and some binary and ternary cement concretes containing fly ash, silica fume and metakaolin to air permeability at equal ... see more

Porous Asphalt (PA) pavements offer an alternative technology for storm water management because it differs from traditional asphalt pavement designs in its high air void ratio which can reach more than 20 %. Aim of the research is to produce porous aspha... see more

Air source heat pump (ASHP) water heaters are efficient devices for sanitary hot water heating. The coefficient of performance (COP) of the air to water heat pump (AWHP) is constantly lower than that of the corresponding ASHP unit. The study focused on de... see more

Raising of problem. If in different atmospheric conditions not only the temperature of the atmosphere but also the quality of the atmosphere must be taken into account, then both supply and exhaust ventilation must be taken into account. Simple systems of... see more

In this study, the relationship between air diffusivity and permeability in cementitious materials was investigated to theoretically investigate the relationship between diffusion and air permeability coefficients. First, an equation to correlate air diff... see more

The authors have been involved in the creation, preliminary tests and development of the “Torrent Method”, which is intended to test air permeability in concrete. It’s been more than 15 years since such foundational research and, now, this paper presents ... see more
