Strength Development and Microstructural Observations of Concrete Incorporating Corn Straw Ash and KH570-Treated Crumb Rubber
Strength losses and poor compatibility between recycled crumb rubber (CR) and cement paste constrain the use of waste-tire polymers in concrete. This study investigated the combined use of corn straw ash (CSA) and KH570-treated crumb rubber (CR) through mechanical testing, microstructural characterization, and compress...
