Concrete: Cement Substitutes. GGBS Producing cement uses a great deal of energy, so finding a waste product that can substitute for cement makes good environmental sense. To varying degrees, cement substitutes work in two ways: • First, they hydrate and cure like portland cement. • Second they are "pozzolans," providing silica that reacts with hydrated lime, an unwanted by-product of ...

The polymer used favored a low water/cement ratio (0.3) which did not allow to decrease resistance due to the fine nature of the materials (residues and cement) in addition to maintaining the workability of the material. The quarry residue was classified as silt with low plasticity and was characterized by X-ray diffraction and Fluorescence to identify 76% of SiO 2, which is why it was used ...
