Obtención De Concretos Autocompactantes Empleando Residuos De Demolición (original) (raw)

Revista Latinoamericana de Metalurgia y Materiales

One of the main environmental problems is the disposal or recycling of big volumes of waste materials from construction and / or demolition. One of the most common materials in these residues are waste clay bricks bonded with cement mortar (masonry waste-MW). Only a city as Bogotá, Colombia, produces approximately 15 million cubic meters each year of debris from construction. Therefore the aim of this investigation was the use of grinding masonry waste in the production of self-compacting concrete (SCC) as a replacement of cement at different percentages, ranging from 10% to 50% by weight. The Properties in fresh state of CAC were assessed using the slump flow cone Abrams, L-box and V- funnel. In order to maintain an adequate flow in the CAC was required increasing dosis of superplasticizer when the replacement of portland cement was greater. There was also an evaluation of mechanical properties such as compression strength and indirect tensile. The best results were obtained with s...
