Prototipo de paneles de madera contralaminada (CLT) con especies maderables del Cantón Naranjal.

Abstract

Housing is a fundamental pillar for human and social development. In Latin America and the Caribbean, and specifically in Ecuador, there is a significant deficit of quality housing units. Wood, a renewable natural resource, has historically been an essential building material. However, in the region, timber construction is often associated with low-quality housing. In this scenario, cross-laminated wood (CLT) emerges as a sustainable and high quality alternative. The general objective of the present research has been to determine the contribution of the physical-mechanical properties of CLT samples with recycled woods of the canton Naranjal in 2023, for the reduction of the housing deficit in Ecuador. The specific objectives include the identification of companies producing these test pieces, the destination of their production and the evaluation of their properties as a viable alternative in the construction sector. The methodology focused on the development of panels and laboratory tests to evaluate the physical-mechanical properties of CLT specimens. Regulations such as ASTM D 143-94, UNE-EN 16351 and technical standard E.070 of Peru were followed. Trials included flexion and compression resistance tests, both perpendicular and parallel to the fibers, and weather durability tests.In the tests carried out, the CLT panels far exceeded the technical regulations in terms of strength and maximum effort, validating their effectiveness and quality. Durability tests confirmed the effectiveness of the glue and the immunization process, even in extreme humidity conditions. In this way, CLT panels are a viable, resilient and sustainable alternative in the construction industry.
