The health of workers in the concrete and cement industries can be at risk due to occupational exposure to silica dust. The purpose of this study was to evaluate the changes of pulmonary parameters and risk of mortality from lung cancer in concrete workers exposed to crystalline silica. This cross-sectional study was performed on 72 male workers ex...

The building sector is responsible for 40% of worldwide carbon emissions, of which 8% can be attributed to concrete construction. With an increased demand for housing, this percentage is bound to increase. This thesis sheds light on strategies for reducing the environmental impact of concrete construction by investigating the potential of structura...

Concrete structures in sewer systems, marine engineering, underground engineering and other humid environments are easily subjected to microbial attachment, colonization and, eventually, deterioration. With careful selection and treatment, some additives including inorganic and organic antimicrobial agents were found to be able to endow concrete wi...

This paper investigates the effect of basalt fibres on the performance of concrete and is designed for applications in flooring and pavement construction. A total of seven concrete mixtures were prepared using various lengths of chopped basalt fibres (12 mm, 36 mm and 50 mm length) with two dosages of 4 kg/m3 and 8 kg/m3, respectively. In order to ...

The increase in the concrete demand due to the rapid industrialization and urbanization may lead to a shortage of natural resources. Therefore, the use of recycled material in the batching of concrete will be helpful to meet the demands of the time without compromising the quality of concrete production. One such waste material produced in Pakistan...

Fuchsova kavárna, která je součástí bývalého zimního stadionu na pražské Štvanici, je významnou kulturní stavbou začleněnou do struktury metropole. Tato funkcionalistická budova je představitelem moderního architektonického stylu, který se v Československu hojně užíval ve 30. letech 20. století, tedy v době, kdy byla budova postavena. Ve městě s ta...

This paper presents the results of resin coating and sand gluing on the acoustic emission (AE) characteristics in the interface failure process of concrete reinforced by polypropylene (PP) fibers. Interface property is an important performance of fibers reinforced concrete, and the pull-out test is the simplest and most effective mean to investigat...

A method is proposed which comprises placing a portland cement concrete or mortar sample with a harmless solution, based on a variety of anthocyanins, which acts as an indicator yielding a color which is visibly different in zones where an alkaline reserve exists (pH ~ 12) (green) from that observed in carbonated areas (pH ≤ 9) (blue). We firstly e...

This paper proposes a method for detection and estimation of the characteristics of defects in concrete structures using laser ablation-induced vibration for non-contact structural inspection to prevent partial spalling. Two types of lasers are used: the first is an impact laser that is used to induce vibrations in the measurement target and the se...

Concrete girders can suffer from serviceability issues due to excessive cracking and deflection. In response to this problem, a novel heat-induced post-tensioning technique utilizing unbonded near-surface mounted nickel–titanium–niobium (NiTiNb) shape-memory alloy (SMA) wires was proposed and evaluated. SMAs are a class of smart materials that can ...
