Behavior of structural lightweight concrete produced with expanded clay aggregate and after exposure to high temperatures

Abstract The residual compressive strength of eight lightweight concrete mixtures containing three commercial grading (Liapor HD 5 N, Liapor 7 and 8F) coarse aggregate (LWA) were determined after to expose at high temperatures. Eight mixes produced, two by normal weight the rest different types LWA. produced was analyzed temperature exposure effect using LWA, type compaction method studied. To do so, visual inspection, strength, crack pattern, spalling, thermoanalytical analysis conducted. Generally, it could be concluded that formulations with LWA behave more advantageous up 500 °C, compared those quartz gravel aggregates. Moreover, this study found an ideal produce structural which used for producing L1 L3.
