The use of limestone in the construction industry has been increasing due to benefits as aggregate. Some of these benefits include good strength, low possibility of alkalisilica reaction and the decrease in drying shrinkage in concrete. This research discusses the consumption and general characteristics of the limestone aggregate in USA and Japan.

All about Limestone Limestone is one of the most common types of rock found on the surface of the Earth. About 10% of the land surface of our planet is made of limestone or similar types of rock; while around 25% of the world''s population either live on or take their water from limestone.
Relevant identified uses of the substance or mixture and uses advised against: Limestone may be used in the manufacture of bricks, mortar, cement, concrete, plasters, paving materials, and other construction materials. Limestone aggregate may be distributed in bags, totes, and bulk shipments. No known recommended restrictions.
fraction of the limestone deposits of the country, it is nevertheless sufficiently abundant and accessible to industrial centers. For some uses, however, dolomite or highmagnesium lime is pre ferred or required. These materials are especially available for blastfurnace flux, being preferable to limestone .

Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an ...
Limestone is a rock consisting mainly or wholly of calcium carbonate and has a tendency to polish smooth under traffic. Therefore, limestone is limited to use in low trafficvolume HMA surface courses. Dolostone under traffic maintains a higherfriction, skidresistant surface and is used on highe r traffic volume locations. Dolostone
Limestone is an acid sensitive stone, similar to marble. It is often used on the floors of homes and businesses and also used to make counter tops, furniture, chalk and in cement production. Limestone has many chemical properties as well as physical properties.

Limestone was most popular in the late 19th and early 20th centuries. Train stations, banks and other structures from that era are normally made of limestone. It is used as a facade on some skyscrapers, but only in thin plates for covering, rather than solid blocks.
Limestone is a collective term for a group of sedimentary rocks that consist of at least 50 percent calcite, a mineral formed of calcium carbonate. If some of the calcium becomes replaced by magnesium, the resulting calcium magnesium carbonate rock is called dolomitic limestone. ... Physical Characteristics of Limestone

The limestone used in agriculture has several different names, including, ''lime.'' Limestone is a finelyground powder, something nearly dissolvable in water. While it doesn''t ever fully dissolve in water or in soil, this type of limestone does supply nutrients, including various oxides.
Limestone use continued to increase through the 1920s, and even into the depression of 192939. During this period, great technical advances were made in quarrying and fabrication techniques enabling Indiana Limestone to hold its competitive edge over the newer manmade products which were appearing on the market.
