listed by the specifier. The specifier must clearly indicate the required use, curing conditions, exposure conditions, surface finish, maximum aggregate size and any excluded materials. In addition the compressive strength class, the maximum water/cement ratio, the minimum cement content, the consistence (slump) and permitted cement types should be quoted. Within these constraints, the producer is responsible for producing a concrete which conforms to the required properties and any additional stated characteristics.
