The Utilization of a Combination of Recycled Rubber from Waste Tires and Waste Waters from a Concrete Plant in the Production of Cement Composites

Abstract

This article presents the results of a study dealing with the use of a combination of recycled rubber from waste tires as a 100% replacement of aggregate and waste sludge water from a concrete plant as a partial replacement of mixing water in the production of cement composites. The aggregate was replaced with recycled rubber material in two ratios. The first ratio was 50/50 and the other one was a 40/60 ratio of fraction 0/1 mm and fraction 1/3 mm. The mixing water was replaced with waste sludge water from a concrete plant in the amounts of 25% and 50%. The designed cement composite formulas were subjected to the test of their physical and mechanical characteristics in order to determine the properties when using a combination of recycled rubber and waste sludge water from a concrete plant. The tested properties include: consistency of the grain curve, mixing water properties, consistency of cement mortar, strength characteristics (tensile flexural strength and compressive strength). The study presents the results that are fundamentally different from the comparative samples and their use in the building industry but, at the same time, they also open up new possibilities of their use as building material.

Determining the Presence of Micro-Particles in Drinking Water in the Czech Republic—An Exploratory Study Focusing on Microplastics and Additives

“…Similar to this study, Pérez-Guevara et al also confirmed the most frequent occurrence of fibers in samples of drinking water [26]. The Fibre category included particles with a length at least 3 times greater than their width.…”

“…One effective approach involves the reutilization of macroplastics, wherein products can be meticulously recycled and upcycled. As an example, tires, which contribute significantly to secondary microplastic sources, could potentially find application in the production of cement composites [26,27]. This innovative reimagining of tire usage presents a promising avenue for curtailing the microplastic menace.…”

Uso Del Caucho De Neumáticos Triturados Y Aplicados Al Concreto: Una Revisión Literaria

“…Las investigaciones más relevantes se concentran en el uso del caucho provenientes de neumáticos reciclados con la finalidad de estudiar la resistencia normal del concreto, pero hay pocos estudios disponibles que analicen el efecto de agregar caucho en el concreto de alta resistencia (Abdelmonem, El-Feky M, Nasr, & Kohail, 2019),así como pocos estudios sobre modelado y predicción de la resistencia a la compresión, las regresiones multivariables no lineales no se han utilizado hasta ahora para la predicción del comportamiento del concreto con caucho (Jalal, Nassir, Jalal, & Arabali, 2019). Su uso práctico como nuevo material en la construcción requiere de una comprensión profunda y una predicción confiable de sus efectos (Svoboda, Václavík, Dvorský, Klus, & Botula, 2020). Por lo tanto, una revisión completa actualizada sobre el concreto con caucho de neumáticos reciclados es necesaria para comprender el comportamiento de este importante material de construcción, aunque se han realizado considerables investigaciones, muchas siguen siendo controvertidas (Li, Zhang, Wang, & Dang, 2019).…”
