Abstract

Beton porous dikenal sebagai porous concrete merupakan salah satu inovasi dalam konstruksi perkerasan jalan yang ramah lingkungan, karena memiliki rongga udara pada permukaan strukturnya yang berfungsi mengalirkan air permukaan kedalam tanah. Beton porous menghasilkan ruang kosong sebagai rongga udara sebesar 15%-25% dari total keseluruhan volumenya serta memiliki nilai slump yang mendekati nol. Selain itu dalam penelitian ini menggunakan fly ash sebagai pengurangan semen dalam beton porous. Tujuan dari penelitian ini untuk mengetahui karakteristik bahan, komposisi campuran beton porous bervariasi, kuat tekan beton porous dan porositas beton porous. Pengujian dilakukan di Laboratorium Struktur dan Bahan Politeknik Negeri Banjarmasin dengan menggunakan metode SNI. Dari hasil penelitian karakteristik bahan semen dan fly ash memenuhi spesifikasi SNI dan hasil pengujian agregat kasar memenuhi spesifikasi. Komposisi beton porous dengan fly ash 0% semen 404,3 kg, air 190 kg/lt, agregat kasar 1-2 1840,7 kg. Komposisi beton porous dengan fly ash 15% semen 343,6 kg, air 190 kg/lt, fly ash 60,6 kg, agregat kasar 1-2 1840,7 kg. Komposisi beton porous dengan fly ash 30% semen 283,0kg, air 190 kg/lt, fly ash 121,3kg, agregat kasar 1-2 1840,7 kg. Hasil kuat tekan beton porous fly ash 0% didapat 20,374 MPa dan porositas 2,34%, beton porous fly ash 15% didapat 21,436 MPa dan porositas 2,07%, dan beton porous fly ash 30% didapat 6,049 MPa dan porositas 6,80%. Porous concrete known as porous concrete is one of the innovations in road pavement construction that is environmentally friendly, because it has air voids on the surface of its structure which functions to drain surface water into the ground. Porous concrete produces empty space as air voids of 15%-25% of the total volume and has a slump value that is close to zero. In addition, in this study using fly ash as a cement reduction in porous concrete. The purpose of this study was to determine the characteristics of the material, the composition of the mixed porous concrete varies, the compressive strength of the porous concrete and the porosity of the porous concrete. The test was carried out at the Structure and Materials Laboratory of the Banjarmasin State Polytechnic using the SNI method. From the results of the research the characteristics of cement and fly ash meet the SNI specifications and the results of the coarse aggregate test meet the specifications. The composition of porous concrete with fly ash 0% cement 404.3 kg, water 190 kg/lt, coarse aggregate 1-2 1840.7 kg. The composition of porous concrete with fly ash 15% cement 343.6 kg, water 190 kg/lt, fly ash 60.6 kg, coarse aggregate 1-2 1840.7 kg. Composition of porous concrete with fly ash 30% cement 283.0kg, water 190 kg/lt, fly ash 121.3kg, coarse aggregate 1-2 1840.7 kg. The results of the compressive strength of 0% porous fly ash concrete obtained 20.374 MPa and 2.34% porosity, 15% porous fly ash concrete obtained 21.436 MPa and 2.07% porosity, and 30% porous fly ash concrete obtained 6.049 MPa and 6.80 porosity. %.
