The use of recycled aggregates in concrete from organic and inorganic origin has been increasing exponentially in recent years. Multiple investigations have been conducted successfully using Rice Husk Ash (RHA) and Eggshell Powder Ash (ESP) as a partial replacement for cement in concrete. In this research, RHA and ESP aggregates are used together to partially replace cement in concrete, for structural purposes. The objective of the study is to make a concrete design with the addition of RHA and ESP that has good workability, which will be measured with the Slump test. In addition, maintaining the flexural and compression resistance of a conventional concrete. Also, reducing the cost and CO2 emissions in the production of materials necessary for concrete. For this purpose, five concrete designs are carried out to analyze the influence of these aggregates together in concrete with different percentages of cement replacement ranging from 10% to 20% of the cement weight. Compressive strength is measured at 7 and 28 days of cure while flexural strength only at 28 days. The cost is clearly evaluated with the materials used and the CO2 emission is measured with the materials and energy used to make these concrete designs. One design with 15% cement replacement achieved greater compressive strength than conventional concrete at 28 days, while reducing CO2 emissions and cost.
