The use of aggregate from electric pole waste material is expected to produce concrete with economic value. The study was conducted by an experimental method in the laboratory, utilizing waste electricity poles broken down to the size of coarse aggregates. The use of waste in the concrete mixture is 20% of the weight of the coarse aggregate and to increase the quality of the concrete, the viscocrete-1003 admixture is used in the mixture. The variation of the admixture used was 0.5%, 1.0%, and 1.5% by weight of cement. Mixed planning using the SNI-03-2847-2002 method. The specimen for compressive strength is cylindrical with a diameter of 150 mm and a height of 300 mm. Compressive strength testing is done on 28 days. The results of the study for normal concrete compressive strength on 28 days were 397.71 kg/cm2. Concrete compressive strength using 20% waste aggregate and the addition of viscocrete-1003 of 0.5%, 1.0% and 1.5% is 427.25 kg/cm2, 469.30 kg/cm2, 506.79 kg/cm2. In general, the higher the percentage of viscocrete-1003, the higher the compressive strength of concrete with a mixture of waste. The admixture of viscocrete-1003 can improve workability, make concrete more flow, and accelerate hardening.
