Green concrete refers to concrete that is environmentally friendly and in the process of making it either reduces environmental pollution or provides conditions for improving the environmental situation. The present research deals with the burial of incinerator ash as the most toxic substance in the process of disposal of waste materials in concrete production. Eco or green concrete obtained by using waste incineration or light ash instead of cement has all the characteristics of normal concrete. The main goal of the laboratory program is to determine the optimal percentage of ash in the mixing plan of manufactured concrete. The samples were selected in such a way that the concrete samples with the percentage of incinerator ash from 0 to 20%, and the SP additive amount of about 2.5% (plasticizer) and the watercement ratio of 0.33 for concrete batches, 50 and 60 and 0.38 for concrete batches 30, 40 and 0.42 are made for concrete batch 20. The percentage value of ash is chosen from zero to 20% so that there is no need for toxic substance leakage tests (TCLP). Based on this program, 100 concrete cube samples with dimensions of 15 x 15 x 15 cm were made and the mixing plan was recorded. After 28 days of making the sample and processing it under the standard conditions of ACI regulations, the sample was subjected to a compressive strength test. The results of the first stage showed that the significant effect of ash from the incinerator on the compressive strength of concrete can be seen. So, for low-grade concrete, 10% waste incineration ash gives the highest resistance, but in high-grade concrete, the effect of increasing waste incineration ash on compressive strength is negative.
