Protected escape routes enable the rescuing of persons to the outside of a building on fire. They are characterized, in particular, by strict requirements relating to the aeration of such spaces. However, the fulfilling of these limits may impact the monitored thermal characteristics of the respective internal areas. The outlined dilemma will be illustrated by way of an example of a protected escape route aerated by positive-pressure ventilation.
For the final quality of the industrial floors with mineral dry-shake toppings is a decisive factor amount of the mineral dry-shake topping in the course of its implementation. Amount of the mineral dry-shake topping affects mainly on the abrasion resistance, which is critical for the real life of the floor. Another important property is the absorbability of the finished floor and mineral shake-layer coherence with the concrete base. This paper summarizes a study on the ideal amount of mineral dry shake toppings when considering the resulting wear resistance of floor surface finish as well as its water absorption and also the adhesion properties of the studied layer to the concrete base.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
