Avaliação de tijolos de adobe com adição de cinzas e fibras do coco

Abstract

The adobe is one of the first building techniques known to mankind, and although old, is still used in the production of affordable housing in many places in the world, especially in rural areas, where access to building materials and new technologies is restricted. The simplicity of implementation and low cost are key benefits to communities far from urban centers. Although, technical advantages are limited compared to other materials, are able to meet the needs of rural areas, for example, thermal, acoustic, fire resistance and insulation sustainability because it does not generate waste and does not require the burning of wood in its manufacturing process. The technique has disadvantages, especially when subjected to the weather, such as rain and sunlight. Therefore, the objective of this work is to verify the performance of adobe blocks with additions of ash from combustion of coal (CCCM) and coconut fiber, as the compressive strength and durability in the presence of water. The experimental part was divided into three steps: characterization of materials; production of the blocks; and evaluation of the same through the test of compressive strength and durability. Adobe blocks with addition of 5%, 10%, 15% and 20% and KCCM blocks with addition of 1%, 3% and 5% coconut fibers were molded. The test results of the compressive strength of the blocks indicate better performance with KCCM addition, since the durability test in the presence of water, the blocks with coconut fibers have the best results
