READY MIX CONCRETE

DESCRIPTION

Ready-Mix Concrete (RMC) Is Concrete That Is Manufactured In A Batch Plant, According To Each Specific Job Requirement (Which All The Raw Materials Are Weighing Batched And Mixed At A Central Batching Plant), Then Delivered To The Job Site "Ready To Use". Ready-Mix Concrete Refers To Concrete That Is Specifically Manufactured For Customers Construction Projects, And Supplied To The Customer On Site As A Single Product. It Is A Mixture Of Portland Or Other Cements, Water And Aggregates: Sand, Gravel, Or Crushed Stone. All Aggregates Should Be Of A Washed Type Material With Limited Amounts Of Fines Or Dirt And Clay. An Admixture Is Often Added To Improve Workability Of The Concrete And / Or Increase Setting Time Of Concrete (Using Retarders) To Factor In The Time Required For The Transit Mixer To Reach The Site.

RMC PROCESS CHART
  • Raw Material Inward: Checking Of Incoming Raw Material As Per IS Frequency
  • Checking And Testing Of Raw Material: Checking The Physical Properties Of Incoming Raw Material Like Sieve Analysis, Specific Gravity & Water Absorption, Bulk Density, Aggregate Impact Value, Flakiness Index, Elongation Index, Moisture Content, Silt Content.
  • Design & Trial New Mixes: Design The Concrete As Per Inward Raw Material Properties And Take The Trial And Tested.
  • Batching & Mixing Of Concrete As Per Pre-Set Mix Design: Batch The Raw Material With Proven And Tested Mix Design At In House Laboratory.
  • Transport The Concrete At Site For End-User: Load The Concrete In TM And Transport At Site Within Time Limit For Smooth Execution.
  • Sampling Take The Sample From The Vehicle For Testing And Validate The Result At Matured Age.

QUALITY ASSURANCE

  • All The Raw Materials Are Stacked In Separate Bins And Are Stored Under Cover So That Aggregates Are Not Exposed To Direct Sunlight And Pollutions.
  • Ensures Quality Check For Each Inward Raw Material.
  • Laboratory Ensures Quality Assurance For Each Batch Of Concrete.
  • Qualified And Skilled Professionals Manning Each Stage Of Operation.
  • Consistent Quality With Every Batch.
  • Assurance Of Desired Compressive Strength In Each Batch Of Concrete.
  • Super Vision During Concrete Pouring And After Completion

TM & PUMP DETAIL

  • Total 8 Nos Of TM With Capacity Of 7 Cu.M In each TM.
  • Total 2 Nos Of Pump Having Pipeline Capacity Up To 100mtr Each.
  • The Mixing Drum and Spirals Are Made Of Highly Wear Resistant Steel with A High Performance Of Chromium (0.8%) And Nickel (0.6%).
  • Transit Mixer Is To Be Covered With Hessian Cloth, Which Is To Be Maintained Wet When TM Is In Use For Maintaining Of Temperature Of Concrete.
  • Own Diesel Tanker For Smooth Movement & Working Of Pump & TM

ADVANTAGE

  • The Use of High Tech Technology, Consistent Methods Produce Excellent Quality Concrete.
  • Less Time Consuming and Delivered In Ready To Use Condition. Can Easily Be Delivered To Multiple Sites Within A Project.
  • Does Not Require Storage Of Construction Materials At The Site.
  • Less Air And Noise Pollution At The Job Site
  • Wastage Of Materials At The Site Is Minimal.
  • Economy in the Use of Raw Materials Results In Conservation Of Natural Resources.
  • Small Or Large Quantities Of Concrete Can Be Delivered Timely At The Construction Site.
  • It Reduced Man-Made Errors At The Site As RMC Has Less Dependency On Human Labourers.
  • It Improved Durability Of Concrete.
  • Ready Mix Concrete Is Environmental-Friendly.
