Performance of Mortar Mixes Using Exfoliated Vermiculite Exposed to High Temperature
For a variety of building and construction applications, mortar mixes are typically produced using fine aggregates, which are being considered one of the most significant cement-based composites. Nowadays, performance evaluation of various types of building materials including mortars under elevated temperatures is receiving more attention by the researchers, especially when it comes to the application level of industrial furnaces and building structures. For a target to achieve better resistance of mortars subjected to high temperatures, addition of thermally stable and porous aggregate may be an alternative. In this study, an attempt has been made to utilize exfoliated vermiculite (EV) as a supplementary material to produce heat-resistant mortar mixes. Different mortar mixes were designed by considering the replacement level of fine aggregate by EV as 5 and 10%. In order to determine the performance of the manufactured mortar mixes, tests on the physical (workability, density), mechanical (compressive strength), and thermal properties of the mortar mixes containing EV are conducted at ambient and elevated temperatures. Ultrasonic pulse velocity test was also conducted to check the quality of the mortar mixes before and after getting exposed to elevated temperatures. Mortar mixes containing EV exhibited excellent strength preservation or poor strength decay rate after exposure to elevated temperatures and also certifies it as a good insulation material.
