Impact of metakaolin on mechanical performance of flax textile-reinforced cement-based composites

De-aluminated metakaolin-cement composite modified with commercial titania as a new green building material for gamma-ray shielding applications

“…The same optimized percentage of DAK was reported in the study of Abdelalim et al, 2008 [30] while 15% DAK was reported in the investigation of Moselhy, 2018 [32]. On the contrary, Majstorovic et al, 2022 confirmed that the replacement of OPC by 30%MK enhanced the mechanical characteristics; this high content of MK participated strongly in CH-free cementitious mortar that increased fiber-matrix interface bond [71].…”

Effect of accelerated aging and silica fume addition on the mechanical and microstructural properties of hybrid textile waste-flax fabric-reinforced cement composites

“…Samples containing approximately 20 mg were heated in an open alumina crucible from 25 • C to 950 • C at 10 • C/min with a flux of nitrogen of 50 ml/min. The percentage of CH in each mixture was calculated from the decomposition of portlandite through Equation ( 3) as previously stated by other authors [22,43]:…”

“…Silva et al [20] managed to improve the durability of the Portland cementitious matrix by incorporating 30% MK and 20% calcined waste crushed clay brick to manufacture composite laminates reinforced with long sisal fibers. Fidelis et al [21] and Majstorović et al [22] developed a CH-free matrix by replacing almost 50% of the PC with MK in jute textile-reinforced concrete and flax textile-reinforced composites, respectively.…”

Effect of reinforcement ratio and textile pre-impregnation on the mechanical properties of flax textile reinforced sulfoaluminate matrix

“…In the context of reinforcement, natural fibers have gained substantial academic attention since they are renewable, biodegradable, inexpensive, lightweight materials, and most importantly is that they are as stiff/strong as synthetic fibers. [24][25][26] Notably, composites reinforced with natural fibers (natural FRCM) have brought the spotlight onto innovative materials, effectively applied to strengthen and retrofit existing structural elements. 24,27,28 Although the use of natural FRCM has proven satisfactory in reinforcing concrete structures, primary concerns center around the durability and low compatibility between the components of this type of composite.…”
