  • Diamond Rmc is supplied in a variety of concrete grades from M-7.5 to M-50 as per IS code IS:10262-1982,(IS:456-2000).
  • Diamond RMC plant has fully equipped laboratory with all test machines to carry out regular and detailed test raw materials, as well as fresh finished concrete.
  • Mix design development & samples when needed.
  • Technical support after & before concrete placement.
  • Monitoring of concrete placement & quality.
  • Evaluating and recommending solution to concrete problem.
Aggregates Testing Done Routinely Accordance With (IS : 383-1970, IS : 2383-1963) :
  • Sieve Analysis
  • Specific Gravity
  • Bulk Density
  • Flakiness & Elongation
  • Impact & Crushing Value
  • Fiteness Modulus
  • Aggregrates Compacity Test
  • Water Absorption & Moisture Content
  • Impurities
How To Minimize The Plastic Shrinkage Cracking :
  • Several Precaution can be taken to minimize it's occurrence
  • PSC does occur during finishing, the finisher may be able to close them by refinishing the surface
  • When adverse condition exist, erect wind break to reduce wind velocity over the surface of concrete and if possible provide sunshade to control surface temperature
  • Dampen the subgrade, formwork and refinforcement
  • Cover the concrete with moisture retaining covering such as wet hessian cloth, plastic sheet etc
  • Start curing the concrete as soon as possible
  • If the area where there are sign of cracking could be re-toweled with wooden float in clockwise fashion, may close the cracks
  • Use systhentic fibers to help resist PSC
