  • Product Description

Specimens were compacted using a needle vibrator. Along with test specimens, cubes and cylinders were also cast for compressive strength determination. Specimens used in the present experimental study conform to RILEM (Reunion Internationale des Laboratoires d''Essais et de Recherches sur les Matériaux et les Constructions) recommendations. The specimen was loaded at mid-span by a concentrated load and was simply supported over span S. A notch of depth a0 is cut into the cured beam. The span-to-depth ratio of the specimen is 3.0. The ratios of notch/depth ratio are 0.15, 0.30 and 0.50. Three identical specimens for each notch/depth ratio and same size were tested. The notch width was around 7mm. All concrete specimens required the use of water reducing agent (superplasticizer) in order to increase its workability. The moulds were filled with concrete in three layers and each layer was compacted well using a needle vibrator. The specimens were de-moulded after 24 hours of casting and cured by immersing them in water. Notches of various depths were cut in beam specimens using a concrete cutting machine.
