A lb/yd³.
Summary:
Because of the amount of handling that occurs during material production, within warehouses, and during manufacturing operations, along with the handling of loading, unloading, and shipping, material mix-ups and mixed materials are not an uncommon occurence. Mixed materials also occur when industrial scrap is collected, or when discarded products are used a new raw material through recycling.
A case of mixed materials has been identified, and you have been called upon to devise a means of separation. Assume that you have the equipment to perform each of the tests described in our discussion. For each of the material combinations below, determine a procedure that could accomplish such a separation. Use standard data-source references to help you identify distinguished properties.

Three samples of aggregates are sieved to obtain the grading curve. A set of different sieves is stacked with the coarsest mesh at the top. The aggregate is then placed in the top sieve and the stack is placed in a sieve shaker. The raw data is as follows: Sieve size (mm) 19 9.5 4.75 2.36 1.18 0.6 0.3 0.15 Pan Mass of sieve (g) 670 620 620 570 570 520 520 520 490 For each sample: Plot the grading curve. a. b. Identify the type of gradation. c. Determine the fineness modulus.
