Autonomní zacelování trhlin v betonu pomocí biokalcifikace se v posledních dvou desetiletích stalo terčem zájmu. Tento článek je zaměřen na dvě hlavní otázky tzv. samohojitelného biobetonu, tj. ochranu bakteriálních spor ...

Reinforced concrete bridges, the arch bridges in particular, which were built even in the first half of the 20th century exhibited a reasonably good safety and durability provided good quality materials were used. ...

Tato studie se zabývá metodologií tvorbě řízených trhlin v laboratorních podmínkách na vzorcích o malých rozměrech. Předchozí experimenty zabývající se zacelováním trhliny využívaly různé postupy pro tvorbu řízených trhlin; ...

The application of self-healing concrete for durability enhancement has become a widely studied topic in recent decades. This paper focuses on addition of a superabsorbent polymer (SAP) to bio-based self-healing concrete ...

The paper is focused on bio-based self-healing concrete. The aim of this method is to ensure durability of concrete structures, which is significantly affected by the microcracks formation. The manual remediation of cracks ...

Concrete with an enhanced self-healing ability caused by metabolic activity of certain bacteria has been widely studied in the recent decades. This paper deals with two of the major drawbacks which have been identified in ...

Crack formation is a common and generally inevitable phenomenon in the field of concrete structures. On the other hand, the ever-increasing demand for sustainable construction, thus the structures durability, has led ...

Durability of concrete structures is significantly affected by the microcracks formation. The manual remediation of cracks is time consuming and financially challenging, thus research of the self-healing potential is a ...

Ačkoliv již bylo provedeno mnoho studií zabývajících se mechanickými vlastnostmi betonu vystaveného působení vysokých teplot, pouze několik z nich se věnovalo betonu provzdušněnému. V tomto článku jsou prezentovány výsledky ...
