The Effect of Newspaper Powder on Structural Concrete Pressure Fc ‘21, 7 Mpa

Abstract

The development of the construction industry in the world will increase the need for concrete as a building material. It will continue to grow as well as the need for further concrete in the future. The Concrete is widely used in construction because it is easily formed according to the needs, especially the concrete-forming materials, namely sand, crushed stone, cement, and water. that materials are not difficult to obtain, maintenance does not require a lot of money, and has high compressive strength. The method used in this research is the experimental method at the Laboratory of the Faculty of Engineering, Universitas Islam Lamongan. In this study, the test object used was a cylindrical specimen with a diameter of 15 cm and a height of 30 cm. The concrete compressive strength test is carried out after the concrete has been immersed for a 7 days treatment period, then a convention is carried out with a correction factor of 28 days. From the results of the normal concrete compressive strength test with 7 days of age converted to 28 days, the average value of 3 samples with a 3% percentage is 18.4 MPa, 5% percentage is 8.6 Mpa, and 10% percentage is 5.8 MPa. From the results of the compressive strength test of paper waste concrete with an age of 7 days converted to 28 days, the composition of 3% is suitable for use. So the 3% percentage of paper waste meets the requirements to be made into fine aggregate in concrete.
