Determination of the Compressive Strength of Concrete Using Artificial Neural Network
International Journal of Engineering and Technology Innovation, 2021 The objective of the work is to estimate the compressive strength of concrete by means of the application of Artificial Neural Networks (ANNs). A database is created with design variables of mixtures of 175, 210, and 280 kgf/cm², which are collected from certified laboratories of soil mechanics and concrete of the city of Jaen.

Design Model for Determination of the Strength Fiber-Reinforced Concrete
IOP Conference Series: Materials Science and Engineering, 2021 Abstract The model of fiber-reinforced concrete for determination of strength under tensile was developed. Formula for assessment of the strength of fiber-reinforced concrete, which takes into account micro-cracks and pores in the materials structure and the presence of reinforcing fibers, was established on the basis of the model ...

Determining the rational compositions of low-strength concretes
Eastern-European Journal of Enterprise Technologies, 2019 The paper reports regularities in the influence of the amount of waste from iron ore enrichment at a rational composition of grain components on strength of concretes with a minimal cement consumption. Low-strength concretes are used in the non-reinforced structures, so they are not subject to the requirement for the minimal cement consumption in order
