“…The index for S1 was close to the laboratory value reported by Wang et al [47] for switchgrass combustion ash (30%) and lower than found for silica fume (75%) and the 68% to 83% found for corncob ash laboratory-combusted at 400 °C, 500 °C or 600 °C [48]. The values for [CaO] reduction in S2 and S3 were comparable to the 3.3% observed by Memon and Khan [48] for corncob ash burnt at 700 °C.…”

“…Recently, some advances in the application of new AWA in cementing systems were reported, including: ashes from banana leafs (Musa sp., Kanning et al, 2014), switchgrass (Panicum virgatum) (Wang et al, 2014), elephant grass (Pennisetum purpureum, Cordeiro and Sales, 2015), bamboo leaf (Bambusa sp., Frías et al, 2012), sugarcane straw (Saccharum officinarum, Moraes et al, 2015), barley straw (Hordeum vulgare, Cobreros et al, 2015) and plane tree (Platanus sp., Binici et al, 2008).…”

“…It is not surprising that we found the largest and most numerous QTL in our study associated with ash content. Wang et al [ 43 ] found that switchgrass ash was composed of 67% SiO 2 , 12% CaO and many other mineral oxides in small concentrations. The high silica content can melt and fuse together when biomass is thermochemically pretreated [ 44 ], thereby causing problems when scaling up fuel conversion methods at the biorefinery.…”

“…The high silica content can melt and fuse together when biomass is thermochemically pretreated [ 44 ], thereby causing problems when scaling up fuel conversion methods at the biorefinery. However, if harvested, the inorganic residue can be recycled into fertilizer [ 45 ] or a cement additive [ 43 , 46 ]. Silica content has many functions in plant tissue including defense from abiotic and biotic stress [ 47 , 48 ].…”
