Journal of Thermal Analysis and Calorimetry - Alkali-activated cements are low-environmental-impact binders and can be obtained from the alkaline activation of wastes such as slags and fly ashes,...     

Evaluation of the acoustic performance of a modular construction system: Case study

The aim of this technical note is to characterize the value of acoustic treatments applied to sustainable buildings. The technique is not common in Brazilian construction, but the market needs construction techniques like the ones that will be showed here. At the end of the article, a comparison between masonry with concrete blocks and the industrialized system (built in steel framing) is presented. The simplified method of measuring acoustics was chosen, to be as close as possible to the regular engineering method. The tested buildings have been classified accordingly. This project made use of the Brazilian law and some European laws.
