Regular Pumping | No Strain | No Clogging

 For concrete contractors, EMC Volcanics perform like a dream every time 

EMC Volcanics deliver outstanding results:

Significant increase of long-term strength & durability, including:

  • Reduced Permeability & Leachability
  • Reduction in Alkali-Silica Corrosion
  • Increased Sulfate- & Chloride-Ion Resistance (e.g. Salt Water Corrosion) 
  • Significantly Reduced Heat of Hydration Mitigates Cracking Issues
  • Concrete Self-healing Properties 

How about strength development? No Problem!

  • Time and time again EMCs have performed as required in all manner of deployments.
  • R&D has been across both domains: academic and industrial.
  • Our EMC Volcanics patent of 2012 was granted based on decades' R&D.
  • Since 2012 we have further devoted R&D exclusively on volcanics.


We have conclusively demonstrated EMC Technology to be "feedstock agnostic", meaning that, provided raw materials are within that as specified in the relevant materials standards (norms) EMC strength-development results speak for themselves. See immediately below.

Now, some data:

79 MPa strength at 70% OPC replacement and 350kg total-cement dose!

 EMC Volcanics—tested by BASF (2020):

  •  55% OPC replacement 
  • Total cement: 365 kg/m3 (564lbs/cu·yd) 
  • Strength development after 7-days: 62 MPa / 9,000 psi
  • Strength development after 28-days: 96 MPa / 14,000 psi 
  • Strength development after 56-days: 100 MPa / 14,600 psi 


 EMC Volcanics—independently tested by a leading Ready Mix supplier (2020-21):

  • 55% OPC replacement 
  • Total cement: 300 kg/m3 (500lbs/cu·yd) 
  • 7-days: 37 MPa / 5,360 psi
  • 28-days: 70 MPa / 10,150 psi 
  • 56-days: 82 MPa / 11,900 psi 


At 70% OPC replacement? In further EMC Volcanics testing, using a total cement dose of 350 kg/m3 (590 lbs/cu·yd), the 50C EN-206 28-day target was smashed — hitting 51.9 MPa in just 7 days! 


 EMC Volcanics—independently tested by a leading Ready Mix supplier (2020-21):

  • 70% OPC replacement 
  • Total cement: 350 kg/m3 (590lbs/cu·yd) 
  • 7-days: 52 MPa / 7,550 psi
  • 28-days: 79 MPa / 11,500 psi 
  • 56-days: 85 MPa / 12,300 psi 


14 non-EMC pozzolans plus OPC reference—tested at the University of Austin, Texas (PDF):

  • Only 20% OPC replacement (113 lbs out of total cement of 564 lbs)
  • Total cement: 335 kg/m3 (564 lbs/cu·yd) 
  • At 7-days: most below 28 MPa / 4,000 psi, none above 35 MPa / 5,000 psi
  • At 28-days: most below 35 MPa / 5,000 psi, two above 41 MPa / 6,000 psi
  • At 56-days: most below 41 MPa / 6,000 psi, one above 48 MPa / 7,000 psi


These results speak for themselves (click here to see full PDF chart).

The EMC Cement difference

Example context: 350 kg/m3 for marine deployments

The strengths indicated in the table below are 28-day values

  • Per BSI guidance, XS3 is for demanding marine environments. 
  • For concrete design the BSI states, "the designer selects a strength class and for the most economic design it is ideal if the strength class is just achieved at the maximum w/c and minimum cement content specified."
  • At 70% substitution, EMC Volcanics smash the requirements — meeting C50's stated 28-day threshold in 7 days, at a total cement content that's even less than the minimum allowed by the various BSI regulations referenced below! Yes? Yes!

The former crack is effectively sealed, forming a formidable barrier to further corrosive attack!

Super-large scale? No problem at all!
