Study On The Effect Of Temperature And Burning Time On The Concrete Compressive Strenght In Mining Laboratory, Department Of Mining Engineering, Faculty Of Engineering Bandung Islamic University
Abstract
MPa. While the concrete samples burned at a temperature of 200°C has the compressive strenght value of 18.60 MPa (30 minutes), 16.98 MPa (60 minutes),15.36 MPa (90 minutes), 13.74 MPa (120 minutes). At temperature 400°C, the compressive strength of concrete samples are 13.87 MPa (30 minutes), 13.06 MPa (60 minutes), then 12.25 MPa (90 minutes), 11.44 MPa (120 minutes). The compressive strength of concrete samples at combustion temperatures of 500°C are 11.09 MPa (30 minutes), 9.77 MPa (60 minutes), 8.45 MPa (90 minutes), 7.13 MPa (120 minutes). The coefficient correlation temperature effect is 0.976 with time effect 0.927, and time and temperature effect is 0.977. This indicates that time and temperature have a very high effect. Based on the results of the test, the compressive strength of concrete samples does not meet the standards of moderate concrete quality.
