Banana leaves ashes as pozzolan for concrete and mortar of Portland cement
Construction and Building Materials, 2014Abstract The worldwide productions of banana were bigger than 95 million tons, which resemble to, approximately, 10.22 million tons of ashes. Additions of these residues or banana leaf ash (BLA) in mortars were investigated by ratios of 0–10% in replacement to weight of the Portland cement as pozzolanic materials.

Efficiency of pozzolans in Portland cement composits
2007Pozzolans materials have long been used as active additions in Portland cement concrete. Among these supplementary cementing materials (SCMs), the industrial wastes produced during various treatments(silica fume, blast-furnace slag and fly ashes) are mainly used to improve the mechanical properties and durability of concrete.

Waste brick’s potential for use as a pozzolan in blended Portland cement
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2010This study investigated the pozzolanic reactions and engineering properties of waste brick-blended cements in relation to various replacement ratios (0—50%). The waste brick consisted of SiO 2 (63.21%), Al 2 O 3 ...

Enthalpy of dehydration of Portland and pozzolanic cements
Cement and Concrete Research, 1989Abstract The dehydration of low temperature phases in Portland and pozzolanic cements and pastes has been studied using a combination of Differential Scanning Calorimetry (DSC) and X-ray Powder Diffraction (XRD). Endotherms associated with the dehydration of gypsum, monosulphate and ettringite were observed by DSC.

Sulfate resistance of portland-pozzolanic cements in relation to strength
Cement and Concrete Research, 1982Sulfate resistance of Portland-pozzolanic cements, prepared by gradual replacement of Portland cement by pozzolana, were studied in relation to their transverse strengths. Common clay and China clay, after calcination, were used as two different pozzolana.

"SP-199: Seventh CANMET/ACI International Conference on Fly Ash, Silica Fume, Slag and Natural Pozzolans in Concrete", 2001
For the repair and strengthening of historical masonry structures, high penetrability injection grouts which use lime, natural pozzolan, portland cement and some with silica fume have been developed. The type, morphology and evolution of the microstructure and hydration products as evidenced by mercury intrusion porosimetry and X-ray diffraction are ...

Pozzolanic effect of porcelain polishing residue in Portland cement
Journal of Cleaner Production, 2015Abstract Ceramic tiling is used on a large scale by the construction industry. The production process of tiles produces porcelain polishing residues (PPR), one of the main residues in the sludge, with loss rates above 1%. Since it is a residue that is impure for reuse in the process, it ends up being discarded in landfills.
