Besides portland cement, concrete might incorporate other cementitious resources which includes fly ash, a waste byproduct from coal burning electrical energy crops; floor slag, a byproduct of iron and steel producing; and silica fume, a waste byproduct within the manufacture of silicon or ferro-silicon metal. A few of these cementitious resources are comparable to the volcanic ashes the Romans combined with lime to get their cement binder.
Ensure your All set blend supplier understands if you can be pumping concrete.
