Comparative study between theoretical values and experimental results of concrete elastici

324 cylindrical test specimens were cast to evaluate the elastic modulus of concrete, a crucial property for deformation control in construction. The study compares experimental results from three concrete classes (C20, C30, C40) made with basalt and dolomite aggregates against six formulations from international norms. Antônio Carlos Santos authored this research, which found the FIB Model Code (2010) and ABNT NBR 6118 (2014) formulations aligned most closely with the experimental data.

Use Cases

• Validating theoretical elastic modulus formulations based on experimental results for different concrete classes.
• Comparing the performance of concrete made with basalt versus dolomite coarse aggregates.
• Benchmarking international code predictions (e.g., ACI 318, EUROCODE 2) against physical test data.
• Training regression models to predict concrete elastic modulus based on mix design and aggregate type.

Strengths

• Experimental data is based on 324 physical test specimens, providing a substantial empirical foundation.
• Results are compared against six formulations from four major international concrete norms and codes, enabling broad benchmarking.
• The study specifies the geographic origin (Triângulo Mineiro region, Brazil) and lithologic types (basalt, dolomite) of the aggregates used.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific rock sources from Brazil.
