| dc.description.abstract | Concrete is a mixture of cement, coarse aggregate, sand and water. This mixture is expected to form a homogeneous material with predictable strength behavior. However, it is very difficult to develop a model to correctly evaluate its onsite strength properties. Common methods used in evaluating and estimating concrete structures are uniaxial compressive strength; core test; and rebound hammer test. This research presents the assessment of compressive strength of cocnrete using rebound hammer, core test and uniaxial compressive strength test to develop relationship between these methods. In this study, cube samples, rebound hammer reading and core samples were extracted from the concrete slabs casted both from two control mix slabs and from four selected project sites for this analysis. Rebound hammer reading and core drilling operations were performed from the casted slabs the same data were collected from rebound hammer versus the project sites under investigation. Descriptive statistical data analysis such as the mean and standard deviation were computed between hammer versus cube and core versus cube strength. The relationship obtained from the variables is expressed as compressive strength of core is 0.732844 times cube strength and compressive strength of rebound hammer 1.11612321 times cube strength and compressive strength estimated from rebound hammer is 1.5241 times compressive strength of core. | en_US |
