Thermal, Mineralogical, and Microstructural Characterizations of Irradiated Polymer Blended Cement Mortar Composites

摘要

In this study, the effects of styrene-acrylic ester (SAE), nanocalcined clay (NCC), and irradiation dose on the thermal, mineralogical, and microstructural characterizations of irradiated polymer-blended cement mortar composites have been investigated. The composites were prepared by partial replacement of cement with 5 and 10% NCC and mixed with sand, SAE latex was added with different ratios (2, 4, 6, 8, 10, and 15%); the composites were subjected to various doses of gamma-irradiation ranged from 10 to 50 kGy. Physicomechanical properties, thermogravimetric analysis, X-ray diffractometry, and scanning electron microscopy techniques were carried out. Mechanical investigation manifested that composites loaded with SAE up to 8% showed the best mechanical performance as compared with composites contains 10 and 15% SAE.
