Since our foundation in the market, we are counted as a reliable supplier for providing Concrete Aggregate. This compound is processed by our experts using best quality materials from the trustworthy vendors. This aggregate have an extensive usage in drainage applications such as foundation and french drains, retaining wall drains, septic drain fields and road side edge drains. Aggregates are also used as base material under foundations, roads, and rail roads. Concrete Aggregate is available at a feasible price.

Aggregates are taken into use in concrete to offer low-cost in the cost of concrete. Aggregates works like a filler only. These do not respond with cement and water.

Composition: Aggregates comprising of substances that can respond with alkalis in cement and make extreme expansion, deterioration and cracking of concrete blend should never be utilized. Consequently, it is obligatory to examine aggregates to know if there is incidence of any such ingredients in aggregate or not.

Size & Shape: The size and form of the aggregate elements importantly impact the amount of cement essential in concrete mix and hence eventually cheap of concrete. For the making of inexpensive concrete mix on should employ chief coarse aggregates reasonable for the construction. IS-456 recommends following commendation to choose the determined size of coarse aggregate to be utilized in P.C.C & R.C.C blend.
Recollect that the size and shape of aggregate particles effect the characteristics of freshly blend concrete more as associated to those of toughened concrete.

Surface Texture: The development of hard bond forte amid aggregate elements and cement paste rests on upon the external texture, surface porosity and surface roughness of the aggregate elements.
If the exterior is rough but absorbent, supreme bond strength progresses. In porous exterior aggregates, the bond forte increases because of leveling of cement paste in the pores.

Specific Gravity: The percentage of weight of oven desiccated aggregates preserved for 24 hours at the temperature of 100 to 1100C, to the heaviness of equivalent volume of water evacuated by saturated dry exterior aggregate is called specific gravity of aggregates.
Specific gravities are chiefly of two sorts.

  • Apparent specific gravity
  • Bulk specific gravity

Specific gravity is a way to adopt the aptness of the aggregate. Low-slung specific gravity usually designates weak, porous, and absorptive substances, while high specific gravity specifies materials of good class. Specific gravity of chief aggregates falls inside the variety of 2.6 to 2.9.
Specific gravity values are also used while designing concrete mix.

Bulk Density: It is well-defined as the mass of the aggregate obligatory to fill a ampule of unit volume. It is usually stated in kg/litre.
Bulk density of aggregates rests on upon the next 3 factors.

  • Grading of aggregates
  • Degree of compaction
  • Shape of aggregate particles

Voids: The empty spaces amid the aggregate elements are recognized as voids. The capacity of void equals the alteration amid the gross capacity of the aggregate mass and the capacity engaged by the particles alone.
Porosity & Absorption: The minute holes shaped in rocks throughout solidification of the molten magma, because of air bubbles, are called as pores. Rocks comprising pores are recognized as porous rocks.

Bulking of Sand: It can be well-defined as in upsurge in the bulk capacity of the amount of sand (i.e. fine aggregate) in a humid condition over the capacity of the similar amount of dry or totally saturated sand. The relation of the volume of humid sand because of the volume of sand while dry, is known as bulking factor.

Fineness Modulus: Fineness modulus is an experiential factor got by addition the growing percentages of collective engaged on each of the normal sieves fluctuating from 80 mm to 150 micron and separating this sum by 100.
Fineness modulus is usually utilized to get an idea of how abrasive or fine the aggregate is. Extra fineness modulus value designates that the aggregate is rougher and small value of fineness modulus shows that the aggregate is better.


  • Excellent strength
  • High dielectric constant
  • Low density
