Effect of Normal and Flaky Aggregate on the Flexural Strength Of R.C.C. Beam

In this thesis the comparative study of flakiness on the flexural strength of RCC beams have been studied using experiments. Total 9 beams have been cast using normal, 5% of 8 mm and10 mm size of aggregates. Non destructive test of the cast beams using Ultrasonic pulse Velocity meter and rebound hammer test have been also carried out. All the specimens (beams) were tested for flexural strength and final load were recorded. Using this flexural strength of the beam calculated and with the help of these tabulated data, relative studies have been carried out to quantify the impact of flakiness. Salient conclusions on this are drawn. All 9 samples/beams have been tested on three point loading system with the help of universal testing machine. Only one type of mixed proportion M20 grade of concrete mix is used. The concrete beam prepared on normal aggregate 95% and 5% of flaky aggregate for different size 8 mm, and 10 mm are tested to determine flexural strength of concrete with the help of destructive and non-destructive test equipments.
