STUDI EKSPERIMEN PENGARUH WAKTU PENUANGAN ADUKAN BETON READYMIX KE DALAM FORMWORK TERHADAP MUTU BETON NORMAL
In the manufacture of the test object, the method used is the method of SNI 2002. The cement used is a cement PPC. The test object is made cylindrical with Æ 15 cm, and 30 cm high of 7 pieces, and a cube of 15 cm x 15 cm x 15 cm as many as 120 pieces. There are eight variations of concrete sample that is normal with old concrete pouring slurry into formwork for 0 minutes, 30 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes, 180 minutes and 210 minutes. Testing / testing specimen include compressive strength test, test setting time, test temperature and shrinkage and elastic modulus test. From the research the compressive strength characteristics of normal concrete with a foundry 0 minutes, 30 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes, 180 minutes, 210 minutes, respectively produce compressive strength of concrete characteristics average (28 days) 319, 51 kg / cm2, 326.30 kg / cm2, 320.26 kg / cm2, 324.04 kg / cm2, 320.26 kg / cm2, 312.71 kg / cm2, 318 kg / cm2, and 259.83 kg / cm2. Modulus of Elasticity average normal concrete with casting time of 0 minutes, 30 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes, 180 minutes, respectively produce Mpa 21614.38, 15691.11 MPa, 20527.44 MPa, 25 097 , 62 Mpa, 26718.54 MPa, MPa 23446.83, 23446.83 MPa. It can be concluded that the longer the time of stirring and pouring concrete into formwork, the compressive strength value produced will decrease. Keyword: pouring slurry, compressive strength, pull out, modulus of elasticity.
