Standard Concrete Mixes (Plain/RCC)

Standard concrete mixes are suitable for Domestic and Commercial use and the ingredients in any particular mix depends on the nature of the application. Such concrete can usually survive a pressure from about 10 MPa (1450 psi) to 40 MPa (5800 psi), with lighter duty uses such as blinding concrete having a much lower MPa rating than structural concrete.

Concrete Grade from C10 to C40 using Ordinary Portland Cement (OPC) or Sulphate Resisting Cement with various water cement ratios. And the minimum concrete strength should be attain at 28 days after curing. 

High-Strength Concrete

High-Strength Concrete are typically used where high compressive loads resistance in required typically used in the erection of high-rise structures and bridges. High-strength concrete has a compressive strength greater than 40 MPa (5800 psi). In the BS EN defines High-Strength concrete as concrete with a compressive strength class higher than C50. High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower.

Durable Concrete

Durable Concrete has the ability to resist weathering actions, chemical attack, and abrasion.

GGBS (Ground Granulated Blast-furnace Slag) is used to protect structure from Chloride Attacks and to limit the temperature rise in large concrete pours.

To reduce thermal cracking caused by heat of cement hydration, Micro Silica is an excellent additive. It also improves the durability and strength.

PFA (Pulverised Fuel Ash) reduce the permeability and improve the long term strength.

Fibre-Reinforced Concrete

Concrete is very durable, but it can be vulnerable to fractures, due to plastic shrinkage, drying shrinkage or heavy load etc. Fibre Reinforced Concrete is a composite material consisting of fibrous material which increases its structural integrity. They are suitable for Warehouse Floors, Elevated Decks, Walls, Pipes, Pavements, Manholes, Roads, Bridges, Aircraft Parking, Runaway, Slope Stabilization and etc.

 

There are different types of Fibre-reinforced concrete

 

Steel Fibre Reinforced Concrete

Macro synthetic Fibres

 

Polypropylene Fibre Reinforced (PFR) Concrete

Micro-synthetic Fibres

Waterproof Concrete

Waterproof concrete is used for long-lasting, durable watertight construction. To improve concrete resistance, water-resisting admixtures are added depending on the application design. To limit water permeability through the concrete itself.

Screed Concrete

The Screed Concrete is usually a simple mixture of cement, aggregate and sand which is used to simply layer pre-existing and cured concrete base for the purpose to improve the appearance of pre-exiting concrete floor or to complete the addition of underfloor MEP systems resulting in even base.

Cellular Lightweight Concrete

Cellular Lightweight Concrete is also known as CLC has several advantages such as being Light Weight, Fire Resistant, Thermal Insulation, Sound Absorption, Termite proof and etc. The foamed concrete is manufactured from mixing of Portland cement, sand, water. The density of the foamed concrete ranges from 400 kg/m3 to 1,800 kg/m3. The lower densities (400 –600 kg/m3): CLC at this range of density are ideal for thermal and sound insulations. The medium densities (800-1000 kg/m3): This density of foamed concrete in attained for manufacturing pre- cast blocks for non-load-bearing work. The high densities (1200kg/m3 to 1800 kg/m3). This is structural- grade material used for Construction of load-bearing walls and ceilings of low rise structures, Formation of partitioning walls, Production of pre-cast blocks for load -bearing work and etc.

Concrete Pile

Concrete Pile foundation are normally used for deep foundation, actually a slender column or long cylinder column used to support the structure and move the load to the desired depth by end-bearing or skin friction.

Subjected to medium and heavy loads, Concrete Piles can be used practically for every types of foundations.
