Different Types Sizes of Aggregate for Concrete ...
· Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths .

Cement, How It Is Produced Mine
Cement plants are typically located central to the minerals required to make the cement, which saves the transportation costs and reduces the price of the cement. Once the ore material to be used for cement has been mined, it is transported to the crushing/screening plant, where it is crushed and screened, to produce the desired particle size ...

Chemical Composition of Cement
Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide. These oxides interact with one another in the kiln at high temperature to form more complex compounds. The relative proportions of these oxide compositions are responsible for influencing the various properties of cement; in addition to rate of cooling and ...

What is Dolomitic Limestone? (with pictures)
Dolomitic limestone is a type of rock that includes up to 50% limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization. This type of rock was once referred to as magnesian limestone in the United States Geological Survey publications ...
