In this constructed environment, the rising prizes of building construction materials are the factor of great worry. The coarse aggregates are the main ingredients used in concrete. We all want that our buildings must be strong, stable and should build with the construction material of reasonable prizes. Every construction industry totally relies on cement, aggregates whether it is coarse or fine for the production of concrete. In this research, pinyon ash, as a waste and useless material, was used to reduce the cement in concrete mixture. The compressive strength of standard cubic and cylinder concrete specimens equipped with 20% of pinyon ash as a substitution of cement is investigated. The properties for fresh concrete are tested for compressive strength at the age of 28 days. It is found that with the with 20 percentage usage of pinyon ash, the compressive strength is acceptable and could be considered as a first step toward using that kind of materials in concrete.
