WATERPROOFING FOR CIVIL CONSTRUCTION WITH REUSE OF GLASS ANDCLAY WASTE

Abstract

In civil construction, several types of waterproofing products based on organic components are used in order to reduce water infiltrations on the walls, comingfrom the subsoil. In this work, it was analyzed the incorporation of a clay and packaging glass residue based on soft drinks, a PMMA polymer, used for waterproofing in civil construction. Formulas were prepared in which a variable percentage of 0 to 40% of the packaging glass residue was added and formulas with 0 to 20% of illitic clay on a PMMA polymer matrix. Five cylindrical specimens of dimensions 75 mm in diameter and 2 mm in thickness were tested for each mold, and they were subjected to technical tests: apparent density, water absorption, retraction, hardness and scanning electron microscopy. In addition, the polymer was tested by the Fourier transform infrared spectroscopy test and its chemistry was determined by X-ray fluorescence. The constituent phases of the clay were determined by X-ray diffractometry. To assess the permeability absorption, three layers of each formulation were applied, with the aid of a brush, on a ceramic base of 11 cm x 11 cm, totaling a rate of 1 kg.m-2in each piece, with an interval of 24h for each layer. After curing, the samples were subjected to a permeability test using an acrylic cylinder. The results of technological properties show that glass up to the limit of 10% and clay up to 20%, exhibits high hardness and apparent density, in addition to low water absorption, and reduces waterproofing in relation to the standard pattern. The product makes room for the use of inorganic materials, in addition to reducing the environmental impact caused by the disposal of glass waste in the environment.
