Oct 31, 2020 These constituents are crushed and blended in the correct proportions and burnt in a rotary kiln. The resulting product is called clinker. The cooled clinker can be mixed with gypsum and various additional constituents and ground to a fine powder in order to produce different types of cement. The main chemical compounds in cement are calcium silicates and aluminates.
Concrete is a composite construction material composed primarily of aggregate, cement and water. Generally Concrete is strong in compression and weak in tension. The aggregate is generally coarse gravel or crushed rocks such as limestone, or granite, along with a fine aggregate such as sand.

So why dont we make something purposive, using eggshell like as an extender or additive for making toothpaste. Eggshells present healthy, balanced calcium due to trace amounts of other minerals contained in it. Eggshell calcium is probably the best natural source of calcium, and it is easier for your body to digest and absorb.

Sep 19, 2018 Crushed stone is mechanically produced. It occurs when crushing machines take a rock deposit and crushes it up to a specified size. The resulting bits of rock are angular and sharp-edged, setting them apart from other types of small stone. Crushed stone is the basic element of most construction projects involving concrete or asphalt.
