The development of concrete from time to time is more advanced, several types of concrete with various uses, one of which is Eco Self Compacting Concrete or commonly called SCC (self-compacting concrete), as well as a mixture of additional materials. from chemicals and materials derived from waste, such as the material we used in this experiment, the material used came from rice husk waste and HVS paper waste, both materials were made to ashes by burning them manually, then ash was sieved. The chemical content contained in rice husk ash has a dominant chemical content of SiO2 86, 91, and paper waste ash has a dominant chemical content is CaO 97, 70. From this previous experiment with the same mixed design without using two ashes, the results obtained are strong press 14, 7 MPa, whereas concrete with the addition of rice husk ash and the results of used paper ash at the age of 1 day get a compressive strength of 22.8 MPa, while at the age of 28 days in the last experiment produced a compressive strength of 49.6 MPa and in this experiment produced compressive strength of 52.3 there is an additional compressive strength of 2.7 MPa. The results of the slump flow on the specimen without using two ashes of 750 mm while with the addition of the two slumps ashes obtained were 650. The conclusion obtained in this experiment the two ashes we used could be as a mixed paste to make SCC concrete.
