Abstract

This research was conducted to test the comparison of compressive strength of concrete using Tonasa cement and Conch cement. Remembering that cement is the most important material in making concrete. So many people use Portland cement in making concrete. The aim of this research is to determine the compressive strength of concrete that is good for use in construction work. In this research, Tonasa cement and Conch cement were used to determine the compressive strength of concrete at the age of 3 days and 7 days in the Ambon State Polytechnic laboratory, civil engineering department. With 12 cylindrical test objects with a diameter of 15 cm and a height of 30 cm. The method used in this research is an experimental method, to investigate the relationship between the compressive strength of compression testing machine concrete and the hammer test number test. the result showed that the  average compressive strength is : Tonasa cement was 41.52 Mpa for cylindrical concrete, 500.23  for cube concrete at 3 days old and 28.16 MPa for cylindrical concrete, 339.32  for cube concrete at 7 days and Conch cement of 38.92 Mpa for cylindrical concrete, 468.97  for cube concrete at 3 years of age. days, and 26.86 MPa for cylindrical concrete, 323.58  for cube concrete at the age of 7 days.

Abstract

Road and Bridge Construction Engineering Study Program, Department of Civil Engineering, Ambon State Polytechnic. The Layeni Village Road Section of Central Maluku Regency is a secondary local cross road that has been damaged at several points on the road so that it must be upgraded from asphalt pavement to flexible pavement (Hotmix) and road complementary buildings. Based on the data analysis process obtained using the 2017 Bina Marga Method, the results for the Asphalt Concrete-Wearing Course (AC WC) layer thickness of 4 cm, for the Asphalt Concrete-Binder Course (AC BC) layer thickness of 6 cm, for the Asphalt Concrete-Base (AC BASE) layer thickness of 18 cm while the 1993 AASTHO Method obtained results for the Surface Course layer thickness of 15 cm, Base Course 10 cm and Sub Base Course 5 cm and for the existing drainage channel discharge obtained 0.31 m3 /second and the plan discharge is 0.98 m3 /second with a discharge difference of 67 m³ /s.
