I am trying to calculate the embodied energy of a concrete mix. i have all the average values for sand, cement, water, coarse aggregate from the ICE database but struggling to get that of water reducing admixture.
Embodied energy of manufacturing of superplasticizing agents depends upon the manufacturer and type in general it is 1.5 to 2 times of the cement manufacturing approximately 9 to 12 Mj per kg. In many countries a high impacts come from transportation if it is imported from far away
