The effect of fiber on the flexural strength of soil-cement

Soil-cement is a combination of Portland cement, soil and water that sticks together due to hydration of cement and compression of its components and creates a dense, durable compound which has low permeability and is resistant to erosion. Due to the fact that soil-cement materials are brittle, they do not show suitable performance under tensile load to failure. In order to compensate for this flaw, we have used three types of fibres to reinforce the materials which are: jute (which is a natural fibre) polypropylene and steel (Which are synthetic fibres). These tests were conducted on three different gradations each with three fine contents with different mineral type (nine different gradations in total). The results show that compressive, strength of soil-cement materials improve dramatically by adding fibres to the matrix
