Determining the proportion of cement, fine aggregate, and coarse aggregate for concrete mix is known as the proportioning of concrete. The principle of proportioning aggregate is that the smaller particle will fill up the voids between large particles. A well proportioned concrete mix requires a minimum amount of cement per unit volume.
by draining. Keep the fine aggregate covered to pre-vent evaporation prior to use in concrete. On the mak-ing day, determine the amount of surface moisture in the fine aggregate and make appropriate corrections in the calculated amount of mixing water to be used. 4.3 Select the amount of dry coarse aggregate

For different mix design the optimum ratio of fine aggregate to coarse aggregate can be changed. It depends to variety of factors considering mainly fresh and hardening phases of concrete.
For fine aggregate, no weight shall be in excess of 4 gm/in. 2 (7 kg/m 2). 3. Coarse Aggregates After the material has been sieved, remove each tray, weigh each size, and record each weight to the nearest 0.1 g. Be sure to remove any aggregate trapped within the sieve openings by gently working from either or both sides with a trowel or

METHOD OF TEST FOR WASHING AND SIEVE ANALYSIS OF COARSE AND . FINE AGGREGATE . SCOPE . This test method covers the procedure used to accurately determine the particle size distribution of coarse and fine aggregate samples; including Base Aggregates, Aggregates for Bituminous Courses, Concrete Aggregates, and other selected materials.
4. Determine the amount of cement, fine aggregate, coarse aggregate and water required to mix and construct five beams, each having the dimensions shown in the figure below. Include a "make-sure-you-have enough" factor of 1.3 in your mix calculations. Assume a w/c ratio of 0.4 and a mix design of 1:2:2.

Cumulative percentage of weight retained on all the six sieves = 292 Fineness Modulus of Fine Aggregates = 292/100 =2.92 kg. Now, when it is desired to obtain a combined aggregate of a definite (required) fineness modulus, F, the amount of fine aggregate (x) to be mixed with 1 volume of the coarse aggregate of a given fineness modulus can be easily determined from the relationship:
