Influence of Water Dosage on the Compressive Strength of Earth Concrete Containing Corn Stalks Fibres

Résumé fourni par la source

The influence of the water content on the compressive strength of the soil – corn stalk fibres – water mixture is analysed in this study. The clay soil is mixed with corn stalk fibres with a water volume variation of 16 to 20% in increments of 1% to produce concrete samples stored in an enclosure at room temperature. On these samples, the density is determined every day to monitor the evolution of water loss as well as compressive strength. It appears that the loss of density decreases with the day and stabilizes from the 26th day and that the best compressive resistance is obtained for a water content of 18%. Keywords: clay soil; corn stalks fibres; compressive strength; water rate.
