9.5.2.3 Testing fresh concrete—Part 10: self-compacting concrete—L box test EN 12350-10:2010. The box test consists of a vertical tank connected to a horizontal channel through an opening in which rebar is placed (Gomes et al., 2002). One of the first references to its use is the work of Petersson et al. (1996).

According to section 19.2.1.3 of ACI 318-19 the specified compressive strength shall be based on the 28-day test results unless otherwise specified in the construction documents. 3- or 7-day test results are used to monitor early strength gain, especially when high early-strength concrete is used.

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.

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 ...
