title = "Computation of required average strength, f'cr, for a specified compressive strength, f'c",

abstract = "This report presents a computer program for the computation of required average strength, f'crbased on the field strength test data. Based on the recent American Concrete Institute Code of practice [ACI 318-83], four different cases, namely: available data more than or equal to 30, available data for two consecutive sets more than or equal to 30, available data more than or equal to 15 but less than 30, and no field data available for comparable concrete are identified and solved. The necessary equations and the flow chart are presented in order to aid the reader to understand the sequence of operations more clearly. Input-output data are explained using example problems. The various example problems illustrate the capability of the program to handle the different cases. The program steps presented are written for Apple Computer. The specialized commands such as HOME are kept to a minimum so that the user can easily modify the program for other types of computers such as IBM or TI.",
