• In printing ink for the making of rubber, plastic, paper, paint and printing ink.

Limestone powder is derived from limestone lumps. It is processed in a sanitary atmosphere utilizing cutting-edge technologies. This powder's main constituent is calcium carbonate, which is also a common ingredient in building materials. calcium carbonate powder is also known as calcite powder. It is found in a variety of plastic, elastomeric, and rubber products. It is used to purify water by removing contaminants and pollutants. Provided powder is frequently used in the manufacture of pigments as well as as a filer for expensive paints. This product comes in great packing to protect it from dirt and dust during shipment.

Use of Limestone Powder

use of limestone powders are shown below:

• Limestone powder is a fine powder made from crushed limestone rock. It is rich in calcium and is commonly used as a filler in various industries, including construction, agriculture, and the chemical industry. use of limestone powder for lawns & limestone powder for yards commonly in India.
• In construction, fine limestone powder for construction is used as a filler in cement, concrete, and asphalt. limestone powder for paint is also used as a component in the production of glass, paint, and ceramic products.
• In agriculture, limestone powder for plants, & limestone powder for gardening is used as a soil amendment to improve soil pH and to provide a source of calcium for plants. It can also be used to neutralize acidic soils and improve crop yields.
• In the chemical industry, limestone powder is used as a filler in the production of various chemicals, such as calcium carbonate, calcium oxide, and calcium hydroxide. It is also used as a neutralizing agent to control pH in various chemical processes.

Limestone powder Feed Grade Specification

The laboratory test findings revealed that replacing up to 15% of the clinker with fine limestone powder with blain fineness values ranging from 4000 to 4500 cm2/gm results in compressive strength comparable to similar mixes generated with 100% conventional Portland cement. It also met the EN 197-1 standard for the standard compressive strength of high early-strength cement (42.5 MPa). Furthermore, it was discovered that adding 25-35% limestone by weight results in somewhat lower compressive strength values than the normal compressive strength requirement for the 28th day.

The substitution of limestone filler for part of the cement has many implications on the physical and chemical properties of cement paste and cured mortar. The majority of research studies have stressed that increasing the amount and fineness of limestone filler (CaCO3) content accelerates the C3S hydration rate due to the creation of a large number of nucleation sites for the precipitation of the hydration products. This improved degree of hydration at an early age is reflected in the strength of both mortars and concretes at an early age.

Numerous studies on Portland limestone cement concentrated on the impacts of limestone on cement performance, limestone participation in hydration reactions, and the production process, notably inter grinding of clinker and limestone.
For numerous reasons, the use of limestone filler in conjunction with Portland cement is a standard practice in many nations across the world, although it has not been practiced in Ethiopia. In recent years, the cost of cement and cement-based construction materials in Ethiopia has risen on a regular basis, and there is a significant imbalance between the demand and supply of cement throughout the country. This growth in cement cost and demand is primarily due to limited production capacity and limited varieties of cement manufactured in the country to meet the country's continual increase in cement demand for buildings.

Limestone Powder in India

Limestone Powder in India is created by processing solid limestone lumps in a sanitary and environmentally friendly manner. It is chemically formulated with the chemical ingredient calcium carbonate. This white limestone powder is used in the production of quicklime with the chemical formula calcium oxide, slaked lime with the chemical formula calcium hydroxide, and cement, among other things. When this product is introduced to water, it removes contaminants and impurities. It is also utilized as a building material in the construction sector, as well as in the production of pigments and expensive paintings. The excess acidity is neutralized by this grade of white limestone powder.
