Failure Patterns of Reinforced Lightweight Aggregate Concrete (RLAC) Walls after High Temperature

This study utilizes and sinters the reservoir sediment to produce high-quality lightweight aggregates. Not only does the recycling of reservoir sediment into useful building material save resources, but it also increases the reservoir capacity, prolongs reservoir life, and is more conducive to environmental protection. This research focuses on this kind of reinforced lightweight aggregate concrete (RLAC) walls. After performing a standard temperature rising fire-resistance test, the failure patterns behavior of the wall sample are studied under a lateral horizontal load. The research results showed that the reinforced lightweight aggregate concrete wall retained its mechanics after the fire-resistance test. The test results also showed that RLAC and reinforced normalweight aggregate concrete (RNAC) walls exerted the same influence on failure patterns.
