Abstract

Concrete mixes have changed significantly over time due to advances in science and technology, including the addition of new ingredients and the replacement of some existing ones. Plastic and fly ash waste which has not been used properly can now be utilized. Due to their negative impact on the environment, these two materials are used. The American Concrete Institute (ACI) 112.4R 1993 method was used for concrete mix planning, with changes in the addition of 1.5% HDPE plastic waste pieces and fly ash with variations of 0%, 5%, 10%, 15%, 20%, and 25% . Based on the results of the concrete flexural strength test, the addition of 1.5% HDPE plastic waste and 5% fly ash gave the best results, namely an increase of 5.300% for concrete aged 28 days and 5.303% for concrete aged 56 days.
