“…Chen et al [54] have studied some propertied of lightweight concretes of which the natural sand is partially replaced with waste LCD glass couples with rubber (1:1) at levels of 0%, 10%, 20%, 30%, 40%, 50%, 60% and 70%, by volume. The results show an increase in the workability of concrete mixtures and bleeding with increasing natural sand replacement.…”

“…Despite these advantages and the environmental and health benefits of recycling worn tires, the use of rubberized building materials is extremely limited owing to several factors [16]. Firstly, the compressive strength and durability of rubberized concrete decreases as rubber aggregates are added [17] [18].…”

Waste tire rubber is a promising lightweight aggregate for building products that enhances their thermal and acoustic properties. Even the environmental benefits of its use are evident, higher cost and significant changes in compressive strength and workability hinder its widespread adoption. This article examines the use of crumb rubber (CR) as aggregate in dry-mix mortars to produce rubberized long hollow blocks and bricks using automated bricks machines. CR was incorporated over a range of 10-40% with water/cement ratio varying from 0.7 to 0.9. The production of rubberized bricks exhibited better performance than long hollow blocks in factory trials. Tests showed important deformations and drastic reduction in compressive strength, especially for crumb rubber percentages greater than 20%. Due to this and the high cost of CR, caution must be taken with the design of new rubberized building products to make sure they are profitable.

“…The former, which can be made from vegetable particles, are of great interest inasmuch as they are renewable (12) and often present good sound absorption capabilities (13). Other materials, also called "green materials", come from recycling processes; some of them use residues coming from construction and demolition wastes (14,15), crumb rubber (16) or plastic waste from recycling of electric wires (17). Besides, these new kinds of materials are expected to satisfy thermal, acoustical and increasingly structural demands.…”

ABSTRACT:The use of sustainable materials is becoming a common practice for noise abatement in building and civil engineering industries. In this context, many applications have been found for porous concrete made from lightweight aggregates. This work investigates the acoustic properties of porous concrete made from arlite and vermiculite lightweight aggregates. These natural resources can still be regarded as sustainable since they can be recycled and do not generate environmentally hazardous waste. The experimental basis used consists of different type specimens whose acoustic performance is assessed in an impedance tube. Additionally, a simple theoretical model for granular porous media, based on parameters measurable with basic experimental procedures, is adopted to predict the acoustic properties of the prepared mixes. The theoretical predictions compare well with the absorption measurements. Preliminary results show the good absorption capability of these materials, making them a promising alternative to traditional porous concrete solutions. RESUMEN: Propiedades acústicas del hormigón poroso a base de áridos ligeros de arlita y vermiculita.El uso de materiales sostenibles se está convirtiendo en una práctica común para la reducción de ruido en las industrias de la edificación e ingeniería civil. Este trabajo investiga las propiedades acústicas de hormigón poroso fabricado a partir de áridos ligeros de arlita y vermiculita. Estos recursos naturales todavía pueden considerarse sostenibles ya que pueden ser reciclados y no generan residuos peligrosos para el medio ambiente. La base experimental utilizada se compone de especímenes de diferente tipo cuyas prestaciones acústicas se evalúan en un tubo de impedancia. Adicionalmente, se ha adoptado un modelo teórico simple para medios porosos granulares, basado en parámetros medibles con procedimientos experimentales básicos, con objeto de predecir las propiedades acústicas de las mezclas preparadas. Las predicciones teóricas muestran una buena concordancia con las medidas de absorción. Los resultados preliminares demuestran la buena capacidad absorbente de estos materiales, haciendo de ellos una alternativa prometedora a las soluciones de hormigón poroso tradicionales.
