What is the most used homogenization method for particulate samples (as soils)? And what is the method to verify if the homogenization did succeed?
MicroDeval is a test that involves measure of resistance of aggregates towards abrasion and test durability of the sample towards grinding of steel balls (ASTM D7428). The medium that is used here is water of room temperature. The sample and charges (steel balls) are kept in the MicroDeval tank and then the apparatus is filled with water.

Grinding was stopped when d90 ≤ 45 μm was achieved. The retained on 45 μmsieve by wet method (ASTM C430), the relative density (ASTM C188) and the Blaine SSA (ASTM C204) were determined. Pozzolanic performance of calcined shales. The pozzolanic activity was evaluated using the Frattini test (EN 196–5) at 2, 7 and 28 days.
Rock mechanics is an important field of geotechnical engineering as it is the theoretical and applied science concerning the physical behavior of rocks and rock masses. Slopes, tunneling, dams foundations and surface constructions requires the characterization of involved rocks and the analysis of their reaction to induced stresses.

In production grinding, it's not always possible to correct a vibration problem as soon as it appears. Rather than stopping, here's a means of continuing to realize smooth, efficient grinding until the underlying cause of vibration can be addressed.
The samples considered in this investigation included a sample stored at 50% relative humidity, covered concrete, a concrete with an exposed vertical surface, a concrete on a drainable base, a concrete on a nondrainable base, and concrete that was submerged. The samples showed that for practical field samples the relative

The diameter of core specimens for the determination of concrete compressive strength should preferably be at least three times ...
Civil Concrete Technology Lectures Notes Concrete Definition In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rocklike mass known ...
