INFLUENCE OF FIBRES ON ROBUSTNESS CHARACTERISTICS OF SELF-CURING CONCRETES. Varatharajan, D. Maruthachalam and V. Poornima
Today water is the most required substance in this era. In generally Curing of concrete is maintaining moisture in the concrete during early ages specifically within 28 days of placing concrete, to develop desired properties. Internal water curing can be used to mitigate self-desiccation and self-desiccation shrinkage. This investigation focuses on the Self-Curing Concrete which doesnt need any necessity of water. The Super absorbent Polymer is used as the curing agent. The percentage of curing agent is 0.3 from the cementations material. The grade of concrete is M40 It was found that SAP could help in self-curing by giving strength on par with conventional curing. The Super Absorbent Polymer is used as the curing agent. The percentage of curing agent is 0.3% by weight of cementanious material. Polypropylene Fibre of 0.1%, 0.2%, 0.3% and 0.5% by volume fraction was added and it is compared with the conventional mix. The effect of variation in strength parameters such as Compressive Strength, Splitting Tensile Strength and Modulus of rupture were studied for different dosage of fibre/self-curing agent and compared with that of cured concrete. Also, the durability study for Self cuing concrete after 28, 56 and 90 days curing was done by conducting the tests such as saturated water absorption, porosity, carbonation depth.
