Flow chart for concrete mix design.

The concrete mix design involves various steps calculations and laboratory testing to find right mix proportions. The concrete hub app now provides an easy fast and free way to perform a preliminary mix design. The main body of the guidelines focuses on the process of reviewing the mix design. In this post you will learn how to design a reinforced concrete beam step by step with my simple to follow flowchart.

Bulk specific gravities and absorptions or moisture content of aggregates. All concrete mixes possess unique properties the design process can be time consuming and challenging. The concrete hub app however solves these challenges associated with creating a unique concrete mix. 1 consistence class s3 should be used for strip foundation concrete and consistence class s4 should be used for trench fill foundation concrete.

Sieve analyses of fine and coarse aggregates. Concrete hub s concrete mix design tool. This process is usually adopted for structures which requires higher grades of concrete such as m25 and above and large construction projects where quantity of concrete consumption is huge. Before starting concrete mix design basic information on raw materials shall be prepared which include.

Approximate mixing water and air content requirements for different slumps and nominal maximum sizes of aggregates water lb cy kg m 3 of concrete for indicated nominal maximum sizes of aggregate slump in mm 3 8 in 9 5 1 2 in 12 5 3 4 in 19 1 in 25 1 1 2 in 37 5 2 in 50 3 in. The flowchart is a representation of the principal properties of aci mix design of concrete workability slump water and air content w c ratio cement coarse aggregate fine aggregate moisture adjustment trial mix civl 1112 aci mix design 3 10. Concrete mix designs are submitted for review so that the reviewer can verify the contractor is interpreting the construction documents correctly. In all other cases the designated mix should be used.

The marshall stability and flow test provides the performance prediction measure for the marshall mix design method. The stability portion of the test measures the maximum load supported by the test specimen at a loading rate of 50 8 mm minute 2 inches minute. 2 st4 mix for house and garage floors may only be used in conjunction with chapter 5 2 suspended ground floors.
