Potentiality of Using a Developed MatLab Program for the Design of High Strength Concrete Mixes

摘要

Concrete mix design is very important as it influences the performance property of designed concrete structures. It is very common that mix design is basically done by hand or developed excel sheets. These methods can be risky and taking long time, therefore a need for an alternative time effective method. This paper presents a developed easy-use program for concrete mix design of high strength concrete (HSC) using a MATLAB program. The program has been developed basing on the Erntroy and Shacklock (1954) mix design method. The tabular and graphical data from the method was converted into appropriate modal equations. An algorithm based on the method was developed utilising the modal equations and specific assumptions which was then coded in a MATLAB program. Thereafter, the developed program was tested using examples from reputable literature. The final results obtained using the program match with the results obtained using a manual approach. It was also noted that, the computation time using the program was faster compared to the manual approach. The design of HSC using a developed MATLAB program shows excellent results and can be used as an alternative to manual approach. This justifies the development of computer aided concrete mix design approaches to save time and increase efficiency.
