Abstract

This research studied concrete design methods. To design concrete using two methods, including the Abrams law and the modified Bolomey method. Concrete with assumed compressive strength 25, 30, 35, 40, and 45 MPa was researched. The research was conducted in the laboratory using two types of samples: cubic 15x15x15cm for compressive strength tests and cylinders ϕ-15cm, h-30cm for the splitting strength tests using the Brazilian method.

The analysis of the cement content in the composition of 1m3 of the mixture showed very large differences depending on the calculation method used. The cement content calculated according to the Abrams method ranged from 180 kg/m3 (25MPa) to 497 kg/m3 (45MPa) depending on the class and determined according to the Bolomey method from 286 kg/m3 (25MPa) to 983 kg/m3 (45MPa). Significant differences were shown in the concrete strength test.

The obtained test results can be the basis for future modifications of the concrete design methods, taking into account additives and admixtures, and can be the basis for the application of artificial neural networks (ANN) to design the composition of concrete.
