Resumen

The increase in CO2 emissions is a global problem, which is why it is necessary to improve the mechanical properties of self-compacting concrete by replacing a percentage of the cement with the incorporation of ashes from agricultural waste. This research aims to evaluate the replacement of cement with rice husk ash and ichu straw ash, in percentages of 2 %, 4 % and 6 % and determine its influence on the fresh properties and compressive strength of self-compacting concrete considering concrete cores at different curing ages. The results showed that the compressive strength increased by 53 % and 40 % with the addition of rice husk ash. It is concluded that replacing 2 % of CCA in the CAC increases its compression resistance from days 3,7,14,21, and 28 days, being a great alternative solution for a high-strength and eco-friendly concrete. with the environment. © Autor(es); 2023.
