Quicklime

Quicklime is successfully applied in the steel manufacturing industry, pulp and paper manufacturers, and for soil stabilization in the cultivation and construction industry.

Quicklime is produced by the thermal dissociation of limestone. Its principal component is calcium oxide. RCI Lime uses limestone aggregates with size ranges from 20mm to 80mm. Quicklime produced is of high quality with a minimum of 90.5% Calcium Oxide content.

 

 

 

Hydrated Lime

Hydrated lime is a value-added downstream product of quicklime. It is a fine, dry powder manufactured by treating quicklime with sufficient water to satisfy its chemical affinity for water, thereby converting oxides to hydroxides.

Hydrated lime is used in many industries such as water and waste water treatment, agricultural applications, flue gas desulphurization and in chemical processing plants. These products are used in many of the same applications as quicklime but hydrated lime is chemically more diluted than quicklime. It is used in industrial applications whereby controlled sizing is needed or where slakes are not utilised.

 

 

CHENG SUN QUARRY

Syarikat Cheng Sun Quarry Sdn Bhd is principally involved in the quarrying of limestone for processing into fine calcium carbonate powder. Cheng Sun Quarry’s plant and factory are in Keramat Pulai, near Ipoh. The raw material which is high quality limestone, is obtained from an adjoining 9-acre limestone hill belonging to the company. The fine calcium carbonate powder is used as a filler in the paint, shoe, plastic and rubber glove industries.

 

BATAMAS

Batamas was incorporated in December 1980 to fulfill the long awaited need for a high quality building material in the country.

Batamas’ core business is in the manufacturing and trading of calcium silicate bricks. Quicklime is one of the essential raw materials required for the production of the bricks. Calcium silicate bricks, subject to British Standard 187, are used as building materials in the construction industry, and they are one of the leading wall-making materials in the world. The product is marketed in Malaysia using the brand name "KALSA".

Batamas factory is located on a 10-acre site in Batu Gajah. The factory utilizes fully automated German Krupp Polysius machinery to produce high quality KALSA calcium silicate bricks.

Batamas initially became an associate of Rock Chemical in August 1996 and subsequently became a wholly-owned subsidiary of Rock Chemical in 2007.

 

Calcium Silicate Bricks

Calcium silicate bricks are made by compressing a mixture of naturally clean raw materials – lime and sand – under high pressure steam; a process which chemically fuses the raw materials to form calcium silicate – a compound that is well known for its heat insulation properties. The lime and sand used is tested for consistency, fineness and purity. During the process of manufacturing, below par bricks are automatically destroyed. The final product goes through impact tests to verify its strength.

Calcium silicate bricks offer a few distinct advantages such as economy, high compressive strength, heat resistance, sound insulation and durability that place them in a class above all other bricks.
