Intelligent system for determining the strength of fiber cement soil

The article discusses the methodology for developing an intelligent system based on an adaptive neuro-fuzzy network, which allows, with an average absolute error MAPE = 0.632 %, to calculate the compressive strength of fiber cement soil, taking into account the content of the additive Portland cement from 4 to 8% and basalt fiber from 0 up to 4% with fiber lengths from 5 to 45 mm. A decrease in the strength of fiber cement soil was revealed when it contained 4% Portland cement and basalt fiber with an average fiber length of up to 10 mm, due to a violation of the homogeneity and insufficient strength of the cement soil matrix to retain the fibers. To achieve maximum strength of fiber cement soil, the optimal content of basalt fiber additive has been established from 2.0 to 2.5 % with an average fiber length of 25 mm.
