Rapid Thermal Analysis Technique for Aggregates in Portland Cement Concrete
Durability of coarse aggregate has a major impact on the durability of Portland cement concrete. Over the past years, there has been an increasing interest in developing and improving test techniques that provide a faster accurate durability assessment which ultimately leads to a better prediction of pavement performance. Thermogravimetric analysis (TGA) is a relatively rapid technique that has shown good potential for use in the analysis of carbonate aggregates. In this work, thermogravimetric technique was used to analyze thirty-one limestone and two dolomite aggregates. The specimens were heated to temperatures above 1000 C using two rates of temperature increase. The weight loss and the change in weight loss as a function of temperature were recorded. The data was acquired by a data acquisition system and later transferred to a microcomputer for analysis.
