to limestone powder at small particle size has a fineness higher than large particle size which results to more reactive. In addition, the small particle size can fill the pore between cement particles in paste that is known as a filling effect. Thus, the fineness of limestone powder used has influence on the observed compressive strength values.

Lime Production: Industry Profile

Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.

Designing Blast Patterns Using Empirical Formulas

According to Bowles (1), limestone is composed mainly of calcium carbonate (CaC0 3). The rock is known as a high-calcium limestone if the magnesium carbonate content is small. The rock is called a magnesium or dolomitic limestone if 10 percent or more of magnesium carbonate is present.

Figure 12.7 Statues made from carbonate compounds such as limestone and marble typically weather slowly over time due to the actions of water, and thermal expansion and contraction. However, pollutants like sulfur dioxide can accelerate weathering. As the concentration of air pollutants increases, deterioration of limestone occurs more rapidly.

Limestone and Acid Rain

Limestone is one familiar form of calcium carbonate. Acids in acid rain promote the dissolution of calcium carbonate by reacting with the carbonate anion. This produces a solution of bicarbonate. Because surface waters are in equilibrium with atmospheric carbon dioxide there
