Quality of Tropical Hardwood Floors

Abstract

This study aimed to determine the basic density of the wood and to simulate the performance of flooring produced with wood from five tropical species: Dipteryx odorata (Cumaru), Handroanthus spp. (Ipê), Hymenaea Courbaril (Jatobá), Astronium Lecointei (Muiracatiara), and Bowdichia virgilioides (Sucupira-Preta). Falling steel sphere, static and dynamic friction, indentation caused by loads applied in small areas, rolling load, and abrasiveness impact tests were simulated. The results were subjected to analysis of variance and Tukey’s test at 5% significance, and Pearson’s correlation was performed between the basic density and the indexes of each flooring. The basic density of the wood flooring made from the evaluated species ranged from 0.735 to 0.958 g.cm-3. D. odorata, Handroanthus spp. and H. courbaril woods were classified as heavy, while those of A. Lecointei and B. Virgilioides as moderately heavy. It was possible to indicate D. odorata, Handroanthus spp., H. courbaril, and B. Virgilioides flooring for environments with intense traffic where there is dragging or falling objects such as industries and companies. The A. Lecointei flooring can be used in residential environments with light traffic, where the loads exerted are low. There was a correlation between the basic wood density and the flooring use simulation tests.

Can Timber Houses Be Productively Faster to Build Than Other Buildings?

“…For safe and useful uses in structures, wood may be strength graded and properties must be available for users, which satisfi es diff erent building codes and regulations (Moya et al, 2015;Görgün and Dündar, 2018). Aesthetically, wood off ers multiple combinations of colors and designs for product fi nishing (Costa et al 2021).…”

Caracterização colorimétrica de pisos de madeiras tropicais amazônicas

“…Na literatura, há diversos estudos que relatam a correlação entre os parâmetros colorimétricos da madeira e a sua densidade básica (Amorim et al 2013, Sousa et al 2019). E segundo Blanco et al (2015), Oliveira et al (2019) e Costa et al (2021), na seleção de matéria-prima para a produção de pisos, a densidade da madeira é um dos principais fatores a serem considerados, pois madeiras mais densas resultam em pisos com maiores valores de resistência nos ensaios de simulação de pisos em uso, como impacto da esfera de aço cadente, atrito estático e dinâmico, carga rolante, ou seja, em ambientes de tráfego intenso sofrerão menos efeito quando da ocorrência de arraste ou queda de objetos, ou seja, terão maior durabilidade ao longo do tempo.…”
