Cement
Our Portland cement is a hydraulic cement produced by pulverizing clinker consisting essentially of
hydraulic calcium silicates, usually containing one or more of the forms of calcium sulfate
as an inter-ground addition.
Our Cement meets ASTM C150, Type I-II, Low Alkali and AASHTO M85 specification requirements and is pre-approved by Louisiana Department of Transportation and Development (LADOTD), Texas Department of Transportation (TXDOT) and North Carolina Department of Transportation (NCDOT).

Coal
Coal is a sedimentary deposit composed primarily of readily combustible carbon. Coal is black or brownish-black, and has a composition that consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous (Consisting of or containing carbon or its compounds) material.
USES Of COAL IN CEMENT PRODUCTION
Globally, 90% of the energy consumed by cement plants is provided by coal. It takes 200 -450kg of coal to produce 1ton of cement.
Coarse Aggregates (Stone)
Our aggregates meet ASTM C33 requirements.
In the field of construction, the term “Aggregates” simply
represent materials like sand, crushed stones, broken bricks, gravel, chips, etc. which are used in the manufacture of traditional cement concrete, asphalt concrete, or various other composite building materials.
Technically they are also called construction aggregates.
These aggregates, simply are a collection of discrete
materials of varying sizes, shapes, and other essentials
attribute. Aggregates can occupy up to 60%-75% volume of composite construction materials like concrete. Thus, their own properties have a significant impact on the overall properties of such composite materials.
Petroleum Coke (Petcoke)
Petroleum coke is an essential and valuable commercial product that is used in a wide range of applications including aluminum manufacturing, fuels and many other products including paint, steel, glass and fertilizers.
Fuel grade petcoke represents nearly 80 percent of worldwide petcoke production and is a source of fuel for cement kilns and electric power plants.
Approximately 26% of the fuel grade petcoke produced is used as fuel for cement kilns during cement production
Fly Ash
The use of fly ash in Portland cement concrete (PCC) has many benefits and improves concrete performance in both the fresh and hardened state. Fly ash use in concrete improves the workability of plastic concrete, and the strength and durability of hardened concrete. Fly ash use is also cost effective. When fly ash is added to concrete, the amount of Portland cement may be reduced.
Benefits to Fresh Concrete: Generally, fly ash benefits fresh concrete by reducing the mixing water requirement and improving the paste flow behavior. Promedkso has a recent SGS report with pending approval of TxDOT.
