Durabilitas Beton Menggunakan Remah Karet Dan Fly Ash Untuk Perkerasan Kaku Di Lingkungan Gambut

---

Rigid Pavement in Peat area requires high durability in order to make concrete could survive in surrounding environment without being damaged for a specified period of time. The research objective was to assess the durability of the concrete mixture of crumb rubber and fly ash with the quality of the 35 mpa fcr concrete plan which is soaked in peat water. In this research, Portland Composite Cement (PCC) concrete with a cement water factor (fas) of 0.3 was used as control concrete. Meanwhile, PCC-CR-FA concrete uses PCC concrete as the main adhesive, crumb rubber is 5% of the weight of fine aggregate, and fly ash is 10% of the weight of cement. Tests for compressive strength, tensile strength, porosity and weight changes were carried out by immersing in peat water for 120 days. The specimens were treated for 28 days in plain water before being immersed in peat water. The test result show that the compressive strength of PCC and PCC-CR-FA concrete increases as the concrete ages after being immersed in peat water. Enhancement of compressive strength of concrete after 120 days of age for PCC and PCC-CR-FA concrete by 8.56% and 13.81% from the initial age of concrete in peat water. The tensile strength of PCC and PCC-CR-FA concrete has decreased by 12.94% and 4.41% from the early age of concrete in peat water. The porosity has decreased at the age of 120 days for PCC and PCC-CR-FA concrete by 0.24% and 0.32% from the early age of concrete in peat water. The weight of PCC and PCC-CR-FA concrete has increased by 0.27% and 0.34% at the age of 120 days compared to the initial immersion age concrete. Based on the result of the test, PCC-CR-FA concrete with a mixture of crumb rubber and fly ash could increase the durability of concrete for rigid pavements in peat area. Key words: Durability, Rigid Pavement, Crumb Rubber, fly ash, Peat Water
