Despite effects that earth construction has ancient origins, it is able to keep a practical and sustainable solution as a result to the environmental issues associated to cement and concrete use. Raw materials contribute in reducing the carbon footprint of the construction sector while serving an excellent thermal comfort and a stable humidity, which make internal environments healthful and energically efficient. In Moroccan lore the earthen plasters have used to coat and safeguard the earth walls. These approaches are accommodated to regional climates and locally abundant materials, and define the legacy for modern sustainable construction. This study investigates the thermal performance of plasters when reinforced with sisal fibers, a renewable and biodegradable natural material. To analyze the impact of sisal fibers on heat transfer and general behavior, various fiber contents (0, 1, 2 and 3 percents) were integrated into the earth mixture. The experimental results were completed by a numerical simulation directed at modeling the behavior of the optimal percentage of sisal fibers under Morocco's subtropical semi-desert climate. The earned results supply valuable wisdoms into how traditional materials can be improved to confront current energy and environmental challenges.

摘要

Despite effects that earth construction has ancient origins, it is able to keep a practical and sustainable solution as a result to the environmental issues associated to cement and concrete use. Raw materials contribute in reducing the carbon footprint of the construction sector while serving an excellent thermal comfort and a stable humidity, which make internal environments healthful and energically efficient. In Moroccan lore the earthen plasters have used to coat and safeguard the earth walls. These approaches are accommodated to regional climates and locally abundant materials, and define the legacy for modern sustainable construction. This study investigates the thermal performance of plasters when reinforced with sisal fibers, a renewable and biodegradable natural material. To analyze the impact of sisal fibers on heat transfer and general behavior, various fiber contents (0, 1, 2 and 3 percents) were integrated into the earth mixture. The experimental results were completed by a numerical simulation directed at modeling the behavior of the optimal percentage of sisal fibers under Morocco's subtropical semi-desert climate. The earned results supply valuable wisdoms into how traditional materials can be improved to confront current energy and environmental challenges.
