The scale ranges from 1 to 14, but few soils are more acidic that 5 or more alkaline than 9. A p H of 7 is perfectly neutral, but most plants grow best when the p H is a slightly acidic between 6.5. Soils in areas with low rainfall tend to be alkaline. Where rainfall is high, soils are more often acidic.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate. Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface. 5.2 Composition 5.2.1 Mineral Content Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt

Common in limestones and shales. Cross sectional views or views looking down on the tops or cups of horn corals can have a circular appearance. Most corals will have grooves or lines radiating out from the axis. They are generally less than 3 or 4 centimeters in width. Cross sectional views through some types of bryozoans are circular.

Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production.

Limestone is strongly effervescent in acid, while dolomite reacts very weakly. As with limestone, dolomite rock originates in warm, shallow marine environments where calcium carbonate accumulates from shell, algae, or coral fragments. It is widespread in the Cambrian Period throughout the world.

The added limestone in the U.S. is modern portland cement and consists of ground clinker, a source of readily soluble sulfates and functional additives. The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding.

Limestone is by definition a rock that contains at least 50% calcium carbonate in the form of calcite by weight. All limestones contain at least a few percent other materials. These can be small particles of quartz, feldspar, or clay minerals delivered to the site by streams, currents and wave action.

Characteristics of Limestone . Limestone is a hard and permeable rock. It consists chiefly of calcium carbonate (CaCo 3) which is insoluble. Limestone areas are generally dry on the surface and for this reason they are known as karst areas. The water seep through (percolate) into it in the lines of weakness called joints or bedding plane.
