Cost and Quality Analysis of the Use of Steel Fiber on Rigid Pavement with Laboratory Experimental Method

Abstract

This study aims to find and compare the cost and quality of the use of steel fiber (dramix) and iron wire mesh in the rigid pavement. The method used in this study is a laboratory experiment. The study results that steel fiber costs less and is more economic than reinforcing steel in rigid pavement. The cost of the 1 m3 of concrete with reinforcing iron wire mesh m8 is equal to Rp. 2.138.34326. At the same time, the cost of a concrete with mixture of 10% steel fiber (dramix) is equal to Rp. 1.798.08900. So, there is cost savings of Rp. 340.25426 for 1 m3. The mixing of steel fiber in concrete has through 28 days greater compressive strength than the ordinary concrete mix with value of compressive strength equal to fcʹ = 29.07 MPa. At the same time, concretes with the mix of steel fiber (dramix) have more compressive strength that varies as follows: fcʹ = 29.34 MPa at 10% of dramix, fcʹ = 29.38 MPa at 15% of dramix, fcʹ = 29.41 MPa at 20% of dramix, and fcʹ = 29.58 MPa at 30% of dramix. In flexural strength test, the concrete with iron wiremesh m8 results flexural strength fcʹ = 4.978 MPa. At the same time, a concrete with the mix of steel fiber (dramix) has more flexural strength that varies as follows: fcʹ = 5.173 MPa at 10% of dramix, fcʹ = 5.316 MPa at 15% of dramix, fcʹ = 5.458 MPa at 20% of dramix, and fcʹ = 5.707 MPa at 30% of dramix.
