Abstract:
Various materials used in capping concrete cylinders were investigated to develop, if possible, a mixture that was economical and would produce caps that within 2 hr would not flow or fracture when the specimen was tested. A fly ash-sulfur mixture was combined in the proper proportions and melted and used at the recommended temperatures produced caps that met all of the requirements.
