Concrete is made as a mixture containing cement, sand, crushed stone and water with a certain composition. The method used in this study refers to SNI 1974-2011 regarding the compressive strength test of concrete with a cylinder measuring 15x30 cm. The purpose of this study was to determine the results of the crushed compressive strength test and slump value with the addition of additive Grolen DP 0%, 3% and 7% at the age variation of 3.7 and 28 days and the planned concrete quality k-225. The results showed that the highest average compressive strength was the addition of Grolen DP 7% or BT 3 additives with a 28 day age variation with a value of 400.22 kg/cm2. The slump value generated by BT 1 shows a slump value of 11.2 cm. BT 2 results in a slump value of 12.3 cm and BT 3 a slump value of 12.9 cm Keywords: Concrete, Compressive Strength, Additive Materials, Age Variation} }
