Abstract

Evaluation of concrete strength in a built-up structure is a major concern to assess conditions of structure with time. In this work some correlations between destructive and nondestructive parameters have been identified. Compressive and tensile strengths are adopted as destructive parameters, whereas rebound numbers and ultrasonic pulse velocity – as nondestructive parameters. The data are limited to concrete grades M20, M30 and M40 with six sets of aggregates widely used in the construction works in Nepal. The data will be helpful in identifying the variations in strength and strength related properties of concrete in already constructed structures and adopt appropriate measures for necessary interventions - maintenance, retrofitting and others in their life time.
