Evaluation of In-place Concrete Strength by Near-to-surface Tests

He compared the bond stress obtained in pull out tests between conventional com- pression strength concrete of 35MPa to compression strength con - crete with rubber residues of

Aiming to determinate the actual compressive strength of concrete of the bridge, Schmidt/rebound hammer tests were carried, which evaluate the surface hardness of concrete and

This unique relationship could then be used to estimate concrete compressive strength on site for any concrete mixture with the same type of cement, regardless of the type

Electrical resistance strain gauges positioned along the steel reinforcement and on the concrete surface at column mid-height were used to measure strains on the steel and

This paper shows the modeling of an ANN capable of performing a nonlinear approach to estimate the concrete compressive strength using the results of steel-concrete bond

The effect of EAFD addition on the axial compressive strength and the tensile strength by radial compression of the concrete samples was evaluated using the tensile strength test 12

It can be concluded that, due to the suitable strength and mechanical properties of the waste steel wire reinforced lightweight concrete compared to the plain lightweight

As a conventional reinforced concrete, the ultimate shear strength of SFRC beams without web reinforcement is primarily influenced by: 1) the compressive strength of concrete, 2)
