PENGARUH PENAMBAHAN LIMBAH GENTENG KARANG PILANG SEBAGAI SUBTITUSI AGREGAT HALUS PADA CAMPURAN PAVING BLOCK TERHADAP KEKUATAN TEKAN DAN DAYA SERAP

Abstract

Karang pilang tile waste can be found in tile production factories, building construction work, and building construction repairs.Therefore it is necessary to hold the utilization of karang pilang tile waste. In this research the use of karang pilang tile waste as material a paving block. The purpose of this research was to analyze the effect of 0%, 5%, 10%, an 15% karang pilang tile waste subtitution on the fine aggregate in the paving block mixture in terms of compressive strength and absorption. This research uses a hydraulic press method with a jack bottle accompanied by a reading so that the strenght applied is uniform to the paving block. The planned paving block measures 20 cm x 10 cm and height 6 cm. Paving block planning that will be used refers to SNI 03-0691-1996. For the compressive strength test use 40 specimens for ages 14 and 28 days. The absorption test use 20 specimens for age 28 days. From the results paving block research at 28 days the average compressive strength the variation of karang pilang tile waste is 0%, 5%, 10%, and 15% respectively 12,07 MPa; 7,73 MPa; 7,14 MPa and 5,96 MPa. The result paving block research at 28 days the average absorption the variation of karang pilang tile waste is 0%, 5%, 10%, and 15% respectively 12,98%; 13,44%; 13,83% and 14,64%. The result of test conducted in the addition of karang pilang tile waste as fine aggregat substitution causes the absorption value to be higher and the compressive strenght value to be lower
