Abstract:
     In the designing calculation of concrete formulation, there are many parameters including: design strength, cement grade, collapse scale, sand rate, sand size, stone kind, stone size etc, all of which can influence the calculated result of formulation design. By utilizing the principle of ordinary arithmatic slide rule and based of the ministry standard of above mentioned parameters. The special slide rule is made to solve the claculation problem of concrete formulation.
