【 摘 要 】

Environs have important influences on the water captivation of concrete materials. This paper presents an investigational study on partial replacement of cement by hypo sludge (paper industry waste) influence of sorptivity and water captivation on the permanence of concrete materials. The sorptivity test measures the rate of movement of water front through the concrete under capillary suction. The waste product from paper industry i.e hypo sludge (HS) is causing serious pollution problem. In this paper the study of sorptivity and water absorption properties of hypo sludge concrete. The cement has been replaced by hypo sludge in the range of 0%, 10%, 20%, 30% and 40% by weight of cement for the M25 and M40 mix. Concrete mixtures were produced, tested and compared in terms of sorptivity and water absorption to the conventional concrete. The mix design was carried out for 1:1.50:3.36 (M25) and 1:0.80:2.29 (M40) proportions of cement concrete on the basis of IS: 10262-2009. The results show that the % water captivation and sorptivity of hypo sludge concrete shows higher % water captivation and sorptivity than conventional concrete.
