The use of waste ash, lately a lot of research is done, in the manufacture of concrete, which aims as an added material, SCM cement replacement material, and so forth. Some ashes that have been used in research into the manufacture of concrete have been tested on chemical content, to determine whether ash from HVS paper waste can be used as a mixture for making concrete, in this experiment the parameters of the chemical content are tested according to the chemicals contained in chemical chemistry. Chemical content research using ASTM method, from the results obtained ash from paper waste ash has a high CaO chemical content above 90%, when compared with the chemical from rice husk ash where the highest chemical content of rice husk ash is SiO2, Conclusion obtained that paper waste ash can be tested as a mixture in making concrete because it has a high CaO content, when compared with the chemical content of cement where the chemical content in cement has a higher CaO chemical content.
