Experimental investigation for shear strengthening of reinforced self
It is noted that the predicted shear strength of beams made of self-compacted concrete using by the ACI 318 [56] code was the most conservative in predicting the ultimate loads, because ACI equation is based on a conventional concrete shear strength database. The shear resistance offered by each strengthening method are described in the ...

Flexural strength test on new profiled composite slab system
Flexural strength is a measure of tensile strength of concrete, a measurement of the ability of a beam or slab to withstand bending moment until failure [13].Girolami et al. [14] investigated the influence of in-plane forces on the flexural load capacity of RC slab and came up with a simple method to measure the strength of the slabs provided known in-plane forces.
