Under the Trial and Error Method of concrete mix design, the ratio regarding the fine aggregate to coarse aggregate is determined by trial to provide the highest weight of the combined aggregate.

The density of particle of fine aggregate and coarse aggregate remain also identical, the mixture that produces the highest weight will contain the maximum solid matter and as a result leads to the smallest amount of voids and surface area.

In another trial mix method, the fine and coarse aggregate are integrated in various ratios. The quantity of cement per unit volume of concrete provides a specific water-cement ratio for each mixture. The percentage of sand is called optimum percentage.

More cement will be needed for the similar consistency when the application of sand is more than optimum. If the quantity of the sand is low, the mix becomes rough. Optimum percentage of sand is reduced due to lower water-cement ratio.

Follow the steps given below to find out the mix proportions of a cement concrete mix by Trial and Error Method.

(a) Choose the water-cement ratio in proportion to the intended target of average compressive strength of concrete and for the desired atmospheric condition.

(b) Determine the workability with regard to slump for selected water-cement ratio for a specific job.

(c) Determine the maximum size of coarse aggregate to be applied or accessible.

(d) The fine and coarse aggregate should be mixed in such a way that either the mixed aggregate contains a grading in proportion to Fuller’s formula or mix aggregate contains a fineness modulus as economical value of fineness modulus for combined aggregate or mix the aggregate in order that the weight per litre of the mixed aggregates becomes the maximum or the sand conforms the optimum percentage.

(e) Find out the quantity of cement needed per unit volume of coarse aggregates to obtain required slump by actual trials.

(f) Determine the genuine proportions of cement, fine aggregate, coarse aggregate and water to satisfy the requirements of strength, workability, durability and economy.
