Additived plaster with rice husk waste

Abstract

The rice husk is an abundant and renewable waste, which can be used as alternative building material instead of those which are commercialized today. The main purpose of this work raises as a study of the behavior of a new material resulting from the mix of plaster and the mentioned waste in different percentages, in order to analyze the results and the feasibility of this new building material “cast-rice husk”, which would reduce the waste and use of raw materials, thus contributing to environmental improvement.For this purpose, specimen test with different percentages of the rice hulls will take place, besides, tests in order to analyze their behavior by comparison with the matrix.The conclusion of these tests are: The addition of rice husk reduces the density of the plaster although it generates a loss of value in the bending strength and compressive strength.This new material can be used as material for the manufacture of prefabricated elements and other structural elements that require low weight. © Springer International Publishing Switzerland 2014.
