Abstract EN

Concrete is wide constructional material which is used in executing most constructive works , because its items are fulfilled , cheap prices & good mechanical features.in addition to its durability , although for its all positive specifications it suffers from negative sides that causes decline in its qualifications & that may lead it to failure.

Many of these problems caused by several reasons , the first one it does not depend clear & specific way when they design the special concrete mixture in every engineering project , also they never check from these mixtures to see who it is good enough or not.

in addition to that there is smooth stack in different steps & that doesn't agree with accredit local specifications.

This research aims to develop the special American way in designing concrete mixtures ACI 211-1-91.& extend the grading and the size of fine aggregate used to include sands having fineness modulus (1-4) which are available in Iraq , and preparing a program by using (Access , visual Basic) which they work in operating system( Windows XP).

This research is designed to help the engineer in designing concrete mixture in short time ,high exactitude& cost by entering the using material specifications & special requirement of fresh and hardened concrete.

after that the program calculate the mix ingredients in Kg required to produce one cubic meter of concrete in addition to the possibility to get mix proportions by weight or volume of concrete or specify the quantities of materials needed to produce a certain volume of concrete.
