Regular Pumping | No Strain | No Clogging

 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!

• 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
