PENGARUH CAMPURAN AIR LIMBAH (AIR SELOKAN) TERHADAP KUAT TEKAN BETON f’c 14.5 Mpa (K-175)

Abstract

Improving technological advances, the use of concrete as a building is very popular in Indonesia. Because it can utilize locally available materias such as crushed stone, pebble, sand, cement and water at a relatively cheap price. In everyday use is often found in construction worker housing projects that use waste water (Water Sewer) for the construction of concrete. This certainly requires a closer examination toward the quality of concrete produced. The method of data analysis begins with a cement investigation, coarse and fine aggregate. Concrete mixing uses clean water (PDAM) as reference and waste water (Water Sewage) from Unisla rusunawa building. From result of analysis which have been done, concrete compressive strength test result at age 7, 14 and 28 days with mixing of clean water equal to 13,68 Mpa, 18,51 Mpa, 21,04 Mpa, while concrete test result at Age 7, 14 And 28 days with Water Sewage mixing of 9.99 MPa, 13.35 MPa and 15.36 MPa.Keywords : Waste Water, Concrete, Compressive Strength
