 · "Pulverization" (comminution, crushing, grinding) is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size. Pulverization has long been done for many materials, including ore, glass, ceramics, grains, paints, and medicines.

For example, the U.S. Depart­ ment of Transportation (DOT) recommends the same degree of pulverization as that used by the Texas Depart­ ment of Highways and Public Transportation: 100 percent passing the 1-in. sieve and a minimum of 80 percent passing the No. 4 sieve (7).

 · For pulverization, three different methods were used: manual grinding with sandpapers, milling in a shaker cryo-mill and milling in a planetary ball mill. The grit designation P150 was used for the p-CA and the s-CA and for the f-CA P1000 (the higher the number is, the finer the sand particles on the sandpaper).

Pulverization in engineering, fine crushing of a solid material (to particles of less than 5 mm). Pulverization is used extensively for the concentration of mineral products in mining, as well as in metallurgy, the chemical industry, and construction. Pulverization has been known since ancient times.

Quality control: FDR with cement follows the same basic procedures used for normal soil-cement operations. The success of a reclamation project depends upon the careful attention to the following control factors: Adequate pulverization Proper cement content Proper moisture content Adequate density Adequate curing.

1. The given soil sample had inadequate strength, and addition of cement will increase the strength and bearing capacity if to be used in construction. 2. Soil-cement samples with higher cement content showed more brittle failures. 3. The cement content has more influence on unconfined compressive strength than curing time. 4.
