“…The lowest coefficient K and effective porosity values observed for brick powder mortars would indicate a higher difficulty of water ingress in those mortars in comparison with CEM I ones, even though the total porosity was always higher. This result confirms that both the pozzolanic activity and the filler effect of the addition are positive from the point of view of the durability, because the combination of both effects causes a more refined pore network [12,49].…”

“…Here, the resistivity was calculated from the impedance spectroscopy R1 values obtained in saturated cylindrical specimens of 10 cm diameter and 5 cm thickness. As has been explained in the section 2.4, the impedance resistance R1 is associated to pores which cross the sample [40], and therefore it is equivalent to the electrical resistance of sample [48,49]…”

“…Regarding the mercury intrusion porosimetry results, the general decrease of the total porosity observed in the short-term (see Figure 7Figure 7) could be related to the progressive development of clinker hydration [49,50] [28] and the pozzolanic reactions of brick powder [9,11], which would form new solid phases, reducing the volume of pores of the materials. The similar values of total porosity obtained for CEM I and BP10 mortars would mean that a replacement of a 10% of clinker by brick powder would hardly have an influence on this parameter.…”

“…This result suggests that in addition to certain pozzolanic activity, they may act as filler, as could be expected since they present some quartz (see Figure 1Figure 1). The reaction promotes pore network refinement, leading to greater shrinkage [48], but the filler acts as a reducer of that phenomenon [49]. The BP20 has more addition, and as a consequence more filler and that could be the reason of the smaller increase in porosity.…”

One way to reach a more sustainable cement industry is replacing clinker by additions, such as waste brick powder. The objective of this research is to analyse the influence in the long-term (until 400 days) of waste brick powder in the microstructure, durability and mechanical properties of mortars which incorporate up to 20% of this addition as a clinker replacement. The microstructure has been studied with the non-destructive impedance spectroscopy technique. According to the obtained results, mortars with 10% and 20% of brick powder, showed good service properties in the long-term, even better than those made with ordinary Portland cement.

“…Önemli bir çevre problemi olan mermer atıkları, her yıl yaklaşık olarak dünyada 5-6 milyon ton Türkiye'de ise 2.5 milyon ton olarak ortaya çıkmaktadır. Bu atıkların değerlendirilmesi üzerine yapılmış birçok araştırma olmasına rağmen maalesef atıklar düzgün bir şekilde bertaraf edilememekte veya geri dönüştürülememektedir (Alyamac et al, 2017;Singh et al, 2017). Mermer atıklarının değerlendirilebilmesi için önemli bir alternatif, inşaat sektöründe kullanılmasıdır.…”

ÖZET: Bu çalışmada, Bilecik bölgesinde bulunan mermer yataklarındaki mermer blokların kesilip, işlenmesi sonucu oluşan atık mermer tozlarının elyaf takviyeli çimento matrisli kompozit (Fiber-Sement; FS) levhaların üretiminde kullanılabilirliği araştırılmıştır. FS levhaların üretimi için ana hammadde olarak çimento, silis kumu, atık mermer tozu ve selüloz kullanılmıştır. Bu hammaddelerin sırasıyla kimyasal bileşimi ve tane boyutu gibi kimyasal ve fiziksel özellikleri ve FS üzerine etkileri araştırılmıştır. Mermer atığı kütlece %0-50 oranlarında eklenmiştir ve FS levhalarının mekaniksel özelliklerine etkileri araştırılmıştır. Üretilen numuneler üzerinde yapılan fiziksel ve mekaniksel test sonuçlarına göre atık mermer tozları kullanılarak kendi grubunda yeterli mekanik özellikleri sağlayan ve daha ekonomik olan elyaf takviyeli çimento matrisli kompozit FS panellerin üretilebileceği belirlenmiştir.Anahtar Kelimeler: Fiber-sement, atık mermer tozu, elyaf takviyeli çimento kompozit. ABSTRACT:In this study, it was investigated the usability of waste marble powders obtained from cutting and processing of marble blocks in marble ores in Bilecik region in the production of fiber reinforced cement matrix composite (Fiber-Cement; FC) sheets. Cement, silica sand, waste marble powder, and cellulose were used as main raw materials for the production of FC sheets. The chemical and physical properties of these raw materials such as chemical composition and grain size, respectively, and their effects on FC were investigated. The marble waste was added to the wt. 0-50% and the effects of mechanical properties of FC sheets were investigated. According to the physical and mechanical test results on the produced samples; it was determined that the fiber reinforced cement matrix composite (FC) sheets can be produced in their class with sufficient mechanical properties and more economically by using waste marble powder.

With the concept of carbon neutrality, the value‐added utilization of biomass materials and solid waste becomes a cutting‐edge topic. Cellulose nanofibrils (CNFs) receive much attention due to their excellent properties in terms of high aspect ratio, specific strength, and specific surface area, but their large‐scale preparation remains a great challenge. Herein, a facile aqueous solution method is proposed for the fabrication of CNFs through artificial stone waste (ASW)‐assisted supramolecular interfacial interactions for the full‐component utilization in cement mortar materials. The strong hydrogen bonding interaction between ASW and CNFs can effectively prevent the intramolecular hydrogen bonding of CNFs and agglomeration of ASW, while improving the stability of CNF/ASW suspensions. The resulting CNFs/ASW with active hydroxyl or carboxyl group can improve the flexural and compressive strength of cement (30.8% and 37.8% higher than that of pristine cement, respectively) by embedding into the defects of cement mortar and promoting the hydration process of cement. In this work, not only a new idea is provided for the large‐scale preparation of biomass nanomaterials, but also the full‐component value‐added utilization of biomass and solid waste in cement materials is opened up.
