EXPERIMENTAL STUDY ON COIR FIBRE REINFORCED FLYASH BASED GEOPOLYMER CONCRETE WITH 12M MOLAR ACTIVATOR

Objective: To investigate the behavior of coir fiber as reinforcement in geopolymer concrete. Analysis: Low-calcium fly ash is used as the production of geopolymer concrete. Before using in concrete coir fiber is treated with latex adhesive solution. Coir fiber of length 25mm with various percentages i.e.., 0%, 0.75%, 1.5%, 2.25%, 3% are used. The combination of Na2SiO3 solution &NaOH result was used for fly ash activation. Binding agent to fly ash ratio was 0.45.The molarity used was 12M (Molars). Ambient curing is followed for this work. Findings: The various strength parameters were tested at various ages i.e.., 7, 14 and 28 days. Applications: Coir fiber which is acting as reinforcement added to resist the micro cracks. So this can be applicable where the requirement to resist the micro cracks.
