After grinding the slags to a typical cement fineness (d' RRSB = 15-16 µm) 50 wt.-% of ground slag and ground Quartz sand (= inert comparison) were mixed with 50 wt.-% of a Portland cement CEM I 42.5 R which fulfilled the requirements for a test cement according to EN 15167-1. Figure 13 shows the strength results for mortars made according ...
Crushed stones #2: ½″ to 2-2/2″ wide. These crushed rocks measure 1-1//2 to 2-2/2 inches, and they are not a popular category. Most vendors don't have them. Some of the uses of number 2 gravel include the following: Large construction jobs, filling large holes, railroad ballast, or making culvert ballast.
The Three Types of Rocks. Rocks are classified based on how they were formed. The three major types are igneous, sedimentary, and metamorphic rocks. This classification is essential to geologists as it provides critical information about the history of specific regions on Earth. These rocks change forms via the rock cycle.
Normal weight aggregate yields concrete with unit weights ranging from 23 to 26 KN/m3 and a specific gravity ranging from 2.5 to 2.7. These aggregates have crushing strengths ranging from 15 to 40 MPa at 28 days. Sand, gravel, and crushed rocks such as granite, basalt, quartz, sandstone, and limestone are typical aggregate examples.
