RAPID THERMAL ANALYSIS TECHNIQUE FOR AGGREGATES IN PORTLAND CEMENT CONCRETE
Durability of course aggregate has a major impact on the durability of Portland cement concrete. Over tha 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 31 limestone and two dolomite aggregates, The specimens were heated to temperatures above 1000 C (1832 F) 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.
