“…Benzer şekilde Zareei vd. [15] %20 vollastonit içeren betonun slump değeri aynı SA içeriği için kontrol betonuna göre %15'e kadar azaldığını göstermiştir. Vollastonitin işlenebilirliğe olan olumsuz etkisi, iğnemsi parçacık yapısının (Şekil 1, Şekil 3) sebep olduğu kenetlenme ile açıklanabilir [16].…”

Bu çalışma kapsamında Finlandiya'dan temin edilen doğal vollastonitin, yüksek performanslı harcın (YPH) dayanım ve durabilite özellikleri üzerindeki etkileri araştırılmıştır. YPH üretim aşamasında su/bağlayıcı oranı sabit tutularak, vollastonit minerali %3, %6, %9, %12 ve %15 oranlarında karışıma eklenmiştir. Ayrıca yüksek oranda su azaltıcı katkı maddesi (SA) vasıtasıyla karışımın işlenebilirliği sağlanmıştır. Basınç, eğilme ve ultrasonik titreşim hızı testleri 3., 7., 28. ve 90. günlerde yapılırken, kılcal su geçirimliliği ve gaz geçirimliliği deneyleri 28. ve 90. günde uygulanmıştır. Bu deneylerden elde edilen sonuçlara göre, %3 vollastonit içeren karışımda tüm deneyler için performansta iyileşme gözlenmiştir. %6 vollastonit içeriğine sahip karışımda ise kontrol harcına oranla daha iyi sonuçlar elde edilirken, %3 vollastonit içeren karışıma göre performansta azalmalar gözlenmiştir.

“…Several studies have been done on the use of ceramic waste as coarse aggregate, powder and filler in the preparation of cement mortar [1][2][3][4][5][6], concrete [7][8][9][10][11][12][13] and self-compacting concretes [14][15][16], high strength concrete [17,18] and ultra-highperformance concrete [19,20]. Many of them, explored that the use of ceramic waste, as a material in concrete composite, leads to a decrease in workability and density of mixture [2,3].…”

This work aims to study the valorization and recycling of ceramic wastes (wall tiles) as a fine aggregate instead of sand in the manufacturing of flowable sand concrete (FSC). For this, the sand is substituted with the ceramic wastes at different dosages (0, 5, 10, 15, 20, and 25% by volume of the sand). The influence of the ceramic wastes addition on the physical (workability, density) and mechanical (compressive, flexural and elastic modulus) properties of FSC was studied. The results show that the use of ceramic waste as partial replacement of sand contributes to reduce the workability, bulk density and improves the mechanical strengths of FSC according to the use of 25% of wall tiles waste.

“…While previous studies have reported dynamic strength enhancement and stiffness gains in concrete with fiber incorporation, these fibers are expensive, which limits their practical applicability in large-scale projects [ 35 ]. An alternative approach can be adopted using economical fiber alternatives, such as waste iron powder [ 32 ], recycled plastics [ 36 , 37 ], other recycled industrial products [ 36 , 38 , 39 ], or affordable natural fibers [ 40 , 41 , 42 , 43 , 44 ]. Natural fibers such as wollastonite, basalt, and wood have been shown to improve the mechanical performance of concrete under either quasi-static or low strain rates [ 41 , 42 , 45 , 46 , 47 ].…”

Wollastonite has gained much attention in the last decade due to its biocompatibility, low thermal expansion, low thermal conductivity, and thermal stability [ 48 , 49 , 50 ].…”

This paper investigates the dynamic compressive behavior of wollastonite fiber-reinforced cementitious mortars using multiscale numerical simulations. The rate dependent behavior of the multiphase heterogeneous systems is captured in a multiscale framework that implements continuum damage towards effective property prediction. The influence of wollastonite fiber content (% by mass) as cement replacement on the dynamic compressive strength and energy absorption capacity is thereafter elucidated. An average compressive strength gain of 40% is obtained for mortars with 10% wollastonite fiber content as cement replacement, as compared to the control mortar at a strain rate of 200/s. The rate dependent constitutive responses enable the computation of energy absorption, which serves as a comparative measure for elucidating the material resistance to impact loads. Approximately a 45% increase in the dynamic energy absorption capacity is observed for the mixture containing 10% wollastonite fibers, as compared to the control case. Overall, the study establishes wollastonite fibers as a sustainable and dynamic performance-enhanced alternative for partial cement replacement. Moreover, the multiscale numerical simulation approach for performance prediction can provide an efficient means for the materials designers and engineers to optimize the size and dosage of wollastonite fibers for desired mechanical performance under dynamic loading conditions.
