摘要: Abstract In this study, the durability properties of concretes involving corn stalk, wheat straw and sunflower stalk ash along with barite colemanite are investigated. Corn substituted in place cement, while fine aggregate different percentages. Concrete specimens were tested for compressive strength at 7, 28 180 days. Furthermore, abrasion freeze–thaw tests performed to investigate physical mechanical properties. 180 day sulfate resistance applied 5% sodium solution (Na2SO4) investigating chemical effect on concrete. Moreover, 12 × 12 × 2 cm mortar samples produced apply radiation shielding test. Am-241 gamma ray source was used The present study showed that use abovementioned ashes improves many engineering By filling voids, produce a stronger concrete, which is further enhanced by barite. Additionally, described additives improve property
