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.

SIMULACIÓN EN SERVICIOS DE PISOS DE MADERA DE PLANTACIONES DE CAPIRONA (Calycophyllum spruceanum)

“…Por otro lado, al comparar con un estudio sobre pisos de madera maciza tropical (COSTA et al, 2021), se observaron valores medios de depresión de 0,195 mm para cumarú y 0,184 mm para ipê, cifras superiores a las obtenidas en este estudio. Esto puede explicarse por la mayor masa básica específica y la mayor edad de dichas especies, como se indica en la investigación.…”

“…Para seleccionar las especies a utilizar para la producción de pisos, se deben evaluar las propiedades físicas, mecánicas y atributos estéticos (COSTA et al, 2021) siendo uno de los factores más importantes para escoger maderas para pisos, la densidad del material, maderas más densas son más resistentes para ser usadas en pisos, dado que la densidad se relaciona directamente, con la dureza (BLANCO-FLORÉZ et al, 2015).…”

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).…”

Janka Hardness Evaluation of Plantation-Grown Eucalyptus nitens for Engineered Flooring Applications

“…The use of timber is common in domestic/commercial flooring applications due to its strong influence on aesthetics [1,2]. The timber flooring products are categorised as solid timber, parquet, engineered and veneer floorings [3].…”
