ABSTRACT
An m-file for mix design of structural lightweight concrete is presented. Mix design of structural lightweight concrete is conducted using guide in the standards. This may be tasking involving reading and understanding of the relevant standards. This renders the process inefficient and liable to errors in computations. A computer approach to mix design will alleviate this problem. An m-file was developed in MATLAB environment for the concrete mix design. The m-file has been tested and has proved to be efficient in computing the mix composition for the first trial batch of lightweight concrete mixes. It can also perform concrete mixture proportioning adjustment.
