There are several additives and admixtures are used to change the composition of concrete or to accelerate or retard its hardening, curing, workability etc., Chemical and mineral admixtures commonly used in production of concrete are too expensive and also polluting the environment. Sisal is a fiber yielding plant whose botanical name is Agave Sisalana. It occupies sixth place among fiber plants, representing 2% of the world’s production of plant fiber. A vast quantity of sisal leaf juice (Extract) is generated during processing of sisal leaves for fiber production, which remain unutilized. It has caused negative environmental impact from its disposal. Research programmes already done to utilize the sisal leaf extract in Medical industry, but not in the construction industry so far, even though it is produced large in quantity. This study aims to use the extract of Sisal leaf, as bio-admixtures in making concrete. The properties of concrete, namely workability, compressive strength, split tensile strength and flexural strength for the three grades viz., M20, M25 and M30 were determined in the presence of 0.50 to 2.0% of sisal leaf extract as admixture in concrete.
