Among the issues to be clariied for the understanding of aggregate grain shape are: if there is an efect regarding the type of sample preparation, which should be the

The aim of this work is the numerical simulation of the mechanical performance of reinforced concrete thin-walled columns, afected by the swelling due to the AAR, emphasizing

Results showed increased bond strength by indirect tensile stress of 15% and 37%; 4% and 12% for the adherence test by oblique shear, and 108% and 178%, for the testing of

onstrates that the cover thickness is inversely proportional to the distance between the spacers. In other words, a distance of 30 cm showed the best performance of all, while

The statistical analysis based on the paired t-test is irst presented for the diameter obtained using the density method. This method was performed to allow for comparison with

The quasi-brittle, loading rate dependent behaviour of the concrete, characterized by a fracture process zone (FPZ) ahead of the crack front, can be described through

The goal of this study is to characterize a sample of steel iber re - inforced concrete and quantify total porosity and steel iber volume to assess thickness spatial distribution

hydraulic conductivity values were similar for all the three mixes in both falling and constant head tests, indicating that the variation of the coarse aggregate gradation used
