Slide 18: RMC group, GA, USA trial results
RMC group, GA, USA: 640C, 25 vs 35 vs 45% FA For personal use only : Black boxes, reference strength drops 600 psi per 10% FA increase : Green boxes, EdenCrete Pz allows ‘no strength loss’ going from 25 to 35% FA : Blue boxes, EdenCrete Pz7 increase strength going from 25 to 35% FA and almost match
Slide 19: Cost-benefit analysis
Cost-benefit analysis 1: Lowest cost of strength with Pz7 in 35% FA mix 2: Greatly reduced cost of ‘theoretical’ 5800 psi mix Cost and CO2 benefits of Pz7 in 640 lb/cy 25% FA mix 3: Reduced CO2 ‘for free’ Batching: Lab trials Doraville, GA June 2022 For personal use only Cost and CO2 benefits of Pz7
