This paper presents the MATLAB based m-file as well as GUI Development Environment (GUIDE) to design a concrete mix calculator. Since, we know that a concrete mix design is prepared under the rules laid out by Indian Standard (IS) codes using different mathematical formulae to compute the ratios of cement, water and aggregates in a concrete mix; it becomes a tedious task to perform these calculations manually. Some researchers prefer to use excel sheets to decrease the computational time, but this methoddoesn't offer data abstraction and human error prevention. As a solution to this problem, a MATLAB based concrete mix calculator has been devised which estimates the proportions of cement, fine aggregates, coarse aggregates (all in Kgs/m3) and water (in Litres) to design a concretemix. The simulated results of proposed calculator have been successfully verified using MATLAB (R2013a) over different types of concrete grades viz. M10, M15, M20 and M25. The designof calculator is in compliance with IS codes 10262:2009, 456:2000 and 383:2016, which lays down basic formulae to compute the concrete mix ratios. This paper presents the detailed explanation of proposed m-file along with the simulated results of GUIDE. Finally, the simulated results are compared with manual computation (accurate up to 3 decimal places). It is concluded that the accuracy of simulated results is higher than manual computation due to absence of quantization errors. Also, the use of simulated environment not only prevents many scopes of human errors, but it also helps in performing complex computations in a very short amount of time, thereby leading a researcher to perform his tasks more productively.
