Abstract
Self Compacting Concrete (SCC) is one solution to get concrete construction which it has good resistance. The durability of concrete was obtained by the good concrete compaction to be done by a skilled workforce. However, one of the negligence that often occurs in the field i.e. after casting they was ignoring curing of the hardening concrete. This study discusses the workability of fresh concrete and mechanical properties (compressive strength and splitting tensile strength) on SCC without curing. Testing of the concrete workability based on EFNARC standard. The mechanical properties test based on ASTM standards. The method Compressive strength test based on ASTM standards 39 / C 39M - 12a, whereas splitting tensile strength accordance standard ASTM C496 / C496M-11. The results of the study indicate that the SCC without curing effect on the reduction in compressive strength at ages 1, 3, 7, 28, and 90 days in a row at 4.11 MPa (16.1%); 4.90 MPa (13.9%); 6.64 MPa (13.1%); and 6, 72 MPa (12.75%). Splitting tensile strength decreased respectively by 0.1 MPa (3.25%); 0.26 MPa (7.99%); 0.4 MPa (9.52%); and 0.39 MPa (9.16%).
