A new lightweight masonry block: Thermal and mechanical performance

The concerns with masonry building envelope performance, particularly thermal efficiency, are causing major changes in masonry solutions, mainly in south European countries, where traditionally the mild winter climate justified the use of high thermal masonry wall performance. The new European Directives regulations require different solutions. This paper describes the development a new masonry system, based on...

Thermal enhancement of plastering mortars with Phase Change Materials:Experimen...

Building materials with incorporated Phase Change Materials (PCM) are meant to increase heat storage capacity, enable stabilization of interior surface temperatures of buildings whereby influencing the thermal comfort sensation and the stabilization of the interior ambient temperatures.This paper presents the development and characterization of a new composite construction material that consists in embedding mi...

A new sound insulation lightweight concrete masonry block. Design and experimen...

The purpose of this paper is to present an innovative design approach for a sound insulation lightweight concrete masonry unit made with expanded clay LECAÒ. This block is especially developed and suited for sound insulation between dwellings and presents an airborne sound insulation that allows realizing separating walls between different houses quicker and with lower costs. In the design phases different wal...

Avaliação hemodinâmica e metabólica da infusão contínua de dexmedetomidina e de...

JUSTIFICATIVA E OBJETIVOS: A dexmedetomidina tem sido utilizada para sedação e como coadjuvante em anestesia geral. O objetivo deste estudo foi avaliar a resposta cardiovascular e simpático-adrenal à intubação traqueal e à insuflação do pneumoperitônio, comparando-a ao remifentanil durante anestesia com sevoflurano para colecistectomia videolaparoscópica. MÉTODO: Foram incluídos no estudo 42 pacientes, estado f...

A new sound absorbing lightweight concrete masonry block

The purpose of this paper is to present an innovative design approach for a sound absorbing lightweight concrete masonry unit made with expanded clay LECAÒ. This new type of block is presented and acoustically characterized. This block is especially suited for sound control in critical listening or performance spaces as well for noise control in noisy environments like industrial areas, power transformers subst...
