Experimental and numerical investigation of accelerated carbonation of recycled fines
Abstract
The purpose of this study is to perform an experimental and numerical study of accelerated carbonation of recycled fines (RF) to assess its potential and kinetics of CO2 uptake and to estimate its interest in a solicitous field of construction environmental impact. First, a parametric study of accelerated carbonation is carried out on RF, varying the following parameters: water content (1, 7, and 25%), fine size (50 μm and 80 μm), carbonation duration (1, 3, 8, 14, 17, and 24 h), CO2 concentration (18 and 100%), and heating temperature of recycled fine (500 °C). Then, the experimental results are used to calibrate a numerical model to simulate the accelerated carbonation of RF in the second step. The experimental and numerical results show the influence of each parameter on the degree of carbonation of the RF. The optimal water content for CO2 uptake is 7%. The CO2 uptake of the finer RF (50 µm) is faster than that of the larger RF (80 µm).
