ingredient in the iron making process. Slag from these furnaces normally are free of objectionable amounts of coke and iron. Chert Chert is a rock of almost any color and is composed of glassy silicon and very fine-grained quartz. Chert breaks into rounded surfaces with sharp edges. Unweathered chert appears hard, dense and brittle with a waxy or

Professor Kamran M. Nemati Winter Quarter 2015 5 Concrete Technology Aggregates for Concrete Concrete Technology 9 Natural mineral aggregates, i.e., sand and gravel have a bulk density of 95 to 105 lbs/ft3 (1520 - 1680 kg/m3) and produce Normal- Weight concrete (NWC).

Olivine is also used to tap blast furnaces in the steel industry, acting as a plug, removed in each steel run. [citation needed] The aluminium foundry industry uses olivine sand to cast objects in aluminium. Olivine sand requires less water than silica sands while still holding the mold together during handling and pouring of the metal.

Moon, meteorite impacts are also responsible for the weathering of basalt. 2.2 Chemical Weathering This type of weathering creates new minerals in place of the ones it destroys in the parent rock. As rocks are exposed to atmospheric conditions at or near the ground surface, they react with components of the atmosphere to form new mine rals.

What is Sand? To a geologist, the word "sand" in sandstone refers to the particle size of the grains in the rock rather than the material of which it is composed.Sand-size particles range in size from 1/16 millimeter to 2 millimeters in diameter. Sandstones are rocks composed primarily of sand-size grains.

Noise and silica exposures are presented by quarry type in Table 2. For basalt excavation and portable crusher plants, mean noise exposures exceeded the hearing protection program level, indicating a need for a plant-wide hearing protection program. For sand and gravel operations, full shift exposures measured with the PEL and hearing protection
