    This document summarizes a sieve analysis test performed on a sample of coarse aggregates. The test involved sieving the sample through a series of sieves and measuring the amount retained on each sieve. This allowed calculating the particle size distribution by percentage and cumulative percentage retained and passing. Based on the results, the fineness modulus was determined to be 4.109, indicating the average particle size was between 2.00 mm and 4.75 mm. Sieve analysis is useful for determining particle size distributions which influence properties of materials like concrete.

    Sieve Analysis of Coarse Aggregates and Fine Aggregates

    Laboratory Report No. 1

    Objectives:

     To learn how sieve analysis is done for coarse aggregates.


     To determine the particle size distribution of coarse aggregate samples.

    Theory:

    Grading of coarse aggregates, also called the testing and analysis of it has been used mainly as an
    economical factor in concrete making. As more aggregates need less water and less cement, however, its
    compressive strength is lesser compared to a concrete that uses finer aggregate, but it needs more water
    and cement for it to be made.

    Under AASHTO M 80 and ASTM C 33, it states that the maximum size of aggregate particles
    generally should not exceed:

    • One –fifth the narrowest dimension of a concrete member


    • Three-Quarters the clear spacing between reinforcing bars and forms
    • One-third the depth of slabs

    These limitations are set for the loading and strength purposes of the concrete, however all the coarse
    aggregates size restrictions are dependent on the engineer’s design of the concrete, it is ultimately the
    engineer that sets the parameters for the sizes of coarse aggregates.

    Conclusion:

    In conclusion, sieve analysis is the simple and easy way to determine the particle size
    distribution. It is also important for analyzing materials because particle size distribution can affect a wide
    range of properties such as the strength of concrete, the solubility of admixture, and even the surface area
    properties. Lastly, based on the result from the computation on the given data, the fineness modulus is
    4.109 which means that the average size particle of given coarse aggregate sample is in between 4 th and
    5th sieves, that is between 2.00 mm to 4.75 mm.
