Abstract:

The rapid increase of the construction industry leads to be a shortage of conventional construction materials such as cement, fine aggregate and coarse aggregate which are mainly used in conventional concrete. Concrete is the most indispensable material being used in construction development throughout the world. Umpteen varieties of concretes (FAC, SCC, FRC, HPC, HSC, and others) were researched in several laboratories and brought to the field to suit the specific needs. The cement industries are releasing a large amount of carbon dioxide during processes that effecting the environment and causing global warming. And by large mining of river sand [fine aggregate], it will cause a decrease in water level in the earth. Then the ground water table is effected, and also river sand is very high cost. Researches were searching for cheaper materials that can be used as a substitute for these materials. And they were studying for low-cost materials as a substitute for the cement materials. The recent studies were shown that the waste from paper industries has pozzolanic property termed as hypo sludge which contains low calcium and the minimum amount of silica. Hypo sludge behaves like cement because of silica and magnesium properties. The magnesium and silica improve the setting of concrete. By utilizing hypo sludge the strength of concrete will be increased and also cost reduction in the concrete is achieved. River sand has been the most popular choice for the fine aggregate of concrete in the past, but overuse of the material has led to environmental concerns, the depleting of securable river sand deposits and a concomitant price increases of material. Therefore, it will obtain cheap and friendly substitutes for river sand that is preferably sea sand. Sea Sand is being used in the construction industry in the Asia Region and also in some European countries. This study is to experiment on suitability, to know the Strength & Durability Of Concrete By using sea sand as a partial replacement for river sand as fine aggregate for concrete & Hypo sludge as the partial replacement for cement in concrete. The work is carried out with M20 & M30 grade concrete. and hypo sludge is replaced in different percentages such as 10%, 20% by weight of cement, and sea sand is replaced in different percentage such as 10%, 20% by weight of river sand. Cubes of 150mm x 150mm size, Cylinders of 150 mm dia and 300mm height, and beams of 100 mm x 100mm x 500mm are cast for conventional concrete and PRH (Replacement of hypo sludge by weight of cement) test specimen respectively.
