Abstract

This study evaluates the influence of incorporating two different types of recycled aggregates (RA) from construction and demolition waste (CDW), brick ceramic aggregate (RA1) and crushed concrete aggregate (RA2), from the city of Bogotá, on the performance of pervious concrete under compression and flexural strength. The substitution of RA in the production of pervious concrete is outlined, taking into account five substitution levels. For the pervious concrete mixes, aggregates of sizes retained in a sieve of 1/2” and 3/8” were used. The pervious concrete mixes were submitted, 28 days later, to density tests, void content, compression and flexural strength and permeability. Such pervious concrete with RA reaches compression and flexural strength of up to 5,79 MPa and 2,14 MPa, respectively, which are within the allowed range by the ACI, reaching a permeability of 24,79 mm/s, value that is superior to the common characteristics of pervious concrete

According to the results found in this research, the characterized recycled aggregates (RA) can be used to produce pervious concrete, since they comply with the ranges presented by ACI (ACI Committee 522, 2010), reaching compression and flexural strength of up to 5,79 MPa and 2,14 MPa, respectively, and a permeability of 24,79 mm/s

Summary

Introduction

The production of construction and demolition waste (CDW) in the city of Bogotá drastically increases every year, which is becoming a problem for the environment. Ulloa-Mayorga, Uribe-Garcés, Paz-Gómez, Alvarado, Torres, and Gasch rainwater with the present system, sooner or later it will not be enough. The improvements were due to the good bonding between the two different types of recycled aggregates and cement paste, and the increased paste content as a result of abrasion and crushing of aggregates particles during mixing In this context, this paper presents results of a pervious concrete using coarse aggregate commercially purchased as brick ceramic aggregate (RA1) and crushed concrete aggregate (RA2) from the city of Bogotá. This paper presents results of a pervious concrete using coarse aggregate commercially purchased as brick ceramic aggregate (RA1) and crushed concrete aggregate (RA2) from the city of Bogotá These concrete mixes have been tested for density, void content, compressive and flexural strength and permeability. They report a permeability of 12,5 mm/s. Aamer Rafique Bhutta et al (2013) developed pervious concrete with the use of crushed concrete as
