Smartphone Application for Determining the Segregation Index of Lightweight Aggregate Concrete

Due to the low density of aggregates and longer mixing times, lightweight aggregate concrete (LWAC) is susceptible segregation aggregates. Several studies have proposed different methods estimate because affects strength durability in structures. Image analysis techniques become very popular for quickly analysing materials and, together with widespread use mobile applications, can make it much easier engineers obtain parameters that identify segregation. The aim this work was development a application photograph section specimen indicate values. A simple, fast, effective implemented, results were validated other previously published results, which facilitate task researchers determine concrete.
