Additioning alfa fibres in cement mortar

Abstract Cement mortar is a broadly used construction material. Adding fibres into the fresh mortar is an effective reinforcing technique to overcome the drawbacks related with the little tensile and flexural strength. Using natural fibres (mostly vegetal) is environmental sustainable and competitiv...
