Experimental and numerical study on the mitigation of autogenous shrinkage of cementitious material

This study experimentally investigated the effects of surfactants and water-repelling agents on the hydration process, relative humidity, and mechanical properties of Portland cement pastes. Based on the measurement results, the degree of hydration, degree of saturation, capillary tension of autogenous shrinkage, and magnitude of autogenous...

Dealing with Heritage: Assessment and Conservation

Conservation of built heritage implies the preservation of values, materials and techniques. Interventions in heritage buildings should be minimal, necessary and compatible in aesthetical and technical sense. The quality of the interventions needs to meet intended and agreed-to standards.This book underlines the importance of a sound assessment...

Facade treatments of historical buildings: Limiting the risks

The usefulness of treatment of facades of historic buildings and especially those with the status of listed monument is often discussed. Surface treatments of facades comprise a range of treatments, from water repellents to consolidants and anti-­graffiti coatings. Even facade cleaning can be considered a facade treatment. Treatment of monuments...

Self-healing of thermal cracks in sandwich panels

Sandwich panels are prefabricated, insulated concrete wall elements, which are sensitive to thermal cracking due to their composition (concrete outer cladding – insulation – concrete inner cladding). During hot days, the temperature of the outer concrete layer can rise up to ~ 60°C and the temperature difference between inner and outer layer...
