Abstract

In carrying out the construction of settlements and other infrastructure, the people of Ambon City, especially the people of Wailawa Hamlet (Tawiri) often use materials in the form of Fine Aggregate (sand) and Coarse Aggregate (gravel) in Ouarry Wailawa as building construction materials and materials for other infrastructure development.  The data collection process was carried out using the experimental method, namely the researcher directly carried out the research and took the required data related to the testing that the researcher was doing. Therefore, the researchers tested the aggregate characteristics, the concrete mix design used SNI 03-2834-2000 and the compressive strength f'c 17 MPa. The results of the research showed that the characteristics of fine aggregate were Wv 1.10 gr / cm3, BJAH 2.08, WC 12.23%, MHB 2.23, C 3.20% and the organic content was dark yellow, from the data from the results of testing the value of volume and weight values. Density does not meet the fine aggregate characteristics testing standards. For coarse aggregate Wv 1.33 gr / cm3, BJAH 2.38, WC 6.43%, MHB 6.57, C 0.90%, from the test results data the value of specific gravity does not meet the standard testing of coarse aggregate characteristics. Mix Design for concrete compressive strength f'c 17 MPa: Cement 394.23 kg, Sand 544.46 kg, Gravel 1051.56 kg, Water 222.75 Kg, Sika fume 3% 11.83 Kg, Sika fume 7% 27.60 Kg, Sika fume 11% 43.37 Kg. Comparison of the compressive strength of concrete at 56 days old for normal concrete 16.89 MPa, concrete with 3% sika fume 15.88 MPa, concrete with sika fume 7% 18.19 MPa, concrete with sika fume 11% 19.63 MPa
