· Hard rock is mechanically crushed or broken mainly for construction aggregates and fill but limestone and dolomite have a range of other uses. Selection of suitable stone depends on mineralogical composition, grain size, grain sorting, cementation, compaction, porosity, weathering state, and the intended use.

Limestone often contains larger crystals of calcite, ranging in size from 0.02 to 0.1 mm (0.79 to 3.94 mils), that are described as sparry calcite or sparite. Sparite is distinguished from micrite by a grain size of over 20 μm (0.79 mils) and because sparite stands out under a hand lens or in thin section as white or transparent crystals.

1. Cost-Effective. One of the primary benefits of using a limestone crusher is its cost-effectiveness. The machine is designed to reduce the cost of production while still delivering high-quality limestone. Additionally, the machine is designed to be energy-efficient, further reducing the production cost. 2.

· The crushed limestone was chosen for two main reasons: The grains’ shape: the angular form of the grain favors the production of fines, while the elongated grains favor particle cruhing. The mineralogy: in limestone, subcritical crack development can be caused by stress corrosion and dissolution, which would amplify the effect of water.

CHAPTER 1—INTRODUCTION. Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.
