Abstract:
The main objective of this study is to find an adequate relationship between the compressive strength of concrete produced by the company SOBOCE.SA in the metropolitan region of Cochabamba-Bolivia with the ultrasound wave speed and the rebound index of the sclerometer. For the elaboration of the study specimens, 15x30 cm cylindrical molds were used, IP40 Portland pozzolanic cement, 3/4" aggregate from the Parotani region, fine sand from the Itapaya region and drinking water without contaminants. In addition, the samples were analyzed through the implementation of non-invasive measurement equipment such as ultrasound following standardized measurement procedures such as the one designated by ASTM C 597-02 and ASTM C 805. Each estimation model found experimentally was tested using the use of data that was collected in the concrete laboratory. The estimated resistances of the cylindrical specimens vary between 15 and 55 MPa at curing ages that are between 3 and 90 days. The results found show that the estimation models of the linear type better relate the compressive strength with respect to the speed of the ultrasound wave and the sclerometer rebound index. Finally, notable differences were found between the estimation models calculated with respect to those found generically in non-invasive measurement equipment.
