Propiedades físicas y mecánicas de un BTC estabilizado con cemento y cáscara de café, para su evaluación constructiva y arquitectónica en la edificación de Vivienda Social

Abstract

Abstract:.The behavior of a BTC stabilized with cementand vegetable fiber such as the coffee husk, its physicaland mechanical properties such as: density, capillarity, porosity, water absorption capacity by immersion and finally resistance to compression are studied.The coffee husk sample was washed with calcium hydroxide and dried for immersion in the BTC manufacturing process; For its characterization, twenty units were developed with a dosage of 10% of cement in relation to the dry weight of its soil, plus 5%, 10% and 15% of vegetable fiber from coffee husks in relation to the dry weight of its soil, pressed with a strength of 19Mpa with automated equipment and curing for 21days.Vegetable fiber had 28% compressive strength but improved impact resistance, the best dosage of vegetable fiber was 10% since it absorbed less water than the other dosages and in turn the opening of pores was ideal allowing a Greater durability of BTC stabilized with cement and coffee husk fiber.
