“…However, synergetic effects of the different pozzolan application were not studied by Le et al 23 and no comparisons with the binary binders were done. The results obtained in this paper were, as for the synergy, in a qualitative agreement also with Soriano et al 24 which was, supposedly, due to the approximately 10% CaO content in the applied fly ash.…”

“…Le et al proposed, as a result of a relatively complex design procedure, several concrete mixtures based on ternary cements with the Portland cement:fly ash:rice husk ash and Portland cement: fly ash: silica fume ratio of 7:2:1 and achieved f c of 120 MPa after 28 days. Soriano et al on the other hand, reported a very substantial synergy achieved using the Portland cement‐fly ash‐spent fluid catalytic cracking catalyst (FCC) binder with a 7:2:1 ratio. The application of FCC led to approximately 20% improvement in f c , as compared with the 7:3:0 and 10:0:0 binders, with the best f c value of 97 MPa after 28 days.…”

Several high‐strength concrete mixes containing ternary binders composed of Portland cement, silica fume, and waste brick powder are designed. Taking into account the functional properties of hardened mixes, together with their supposed environmental qualities and economic benefits, the practical limits of pozzolan content in the binder are analyzed. Based on a wide set of material characterization experiments including mercury intrusion porosimetry, scanning electron microscopy, and X‐ray diffraction analysis, complemented with a series of measurements of basic physical properties, mechanical parameters, and water and water vapor transport properties, the binder consisting of 57% Portland cement, 18.5% silica fume, and 24.5% brick powder is identified as the optimum in the studied system. The excellent functional properties of the mix with such a high pozzolan content are achieved due to the synergetic effects of the combination of silica fume and waste brick powder on concrete properties. The fineness of brick particles, together with the dual character of the applied brick powder acting as active pozzolan and microfiller at the same time, is found to magnify the ability of silica fume to fill the intergranular space through the improvement of the granulometry curve.

“…Due to the dilution effect and slow pozzolanic reaction, FA has an adverse effect on the early-age strength of mortar. The early-age strength goes down for a cement replacement by FA in the range of 10%-70% [24,26,[28][29][30]43,89,160]. The use of 40% FA causes a 34% decrease in the 28-day tensile strength of mortar [26].…”

“…The strength gap between the mortar with OPC alone and the mortar with binary FA-OPC binder decreases with age. In some studies, it took 90 days to show a similar or better strength compared to the control mortar [28,29]. Other investigations have shown that it took a longer time to gain a similar strength [26,43].…”

Utilization of By-Products and Wastes as Supplementary Cementitious Materials in Structural Mortar for Sustainable Construction

et al. 2020

Rapid growth in industrial development has raised the concern of proper disposal of the by-products generated in industries. Many of them may cause serious pollution to the air, land, and water if dumped in open landfills. Agricultural and municipal wastes also cause environmental issues if not managed properly. Besides, minimizing the carbon footprint has become a priority in every industry to slow down global warming and climate change effects. The use of supplementary cementitious materials (SCMs) obtained from agricultural, industrial, municipal, and natural sources can decrease a significant amount of fossil fuel burning by reducing cement production and contribute to proper waste management. Also, SCMs can enhance desirable material properties like flowability, strength, and durability. Such materials may play a big role to meet the need of modern time for resilient construction. The effective application of SCMs in cement-based materials requires a clear understanding of their physical and chemical characteristics. Researchers studied how the flowability, strength, and durability properties of structural mortar change with the replacement of cement with different SCMs. Various experiments were conducted to examine the behavior of structural mortar in extreme conditions (e.g., high temperature). Many scholars have attempted to improve its performance with various treatment techniques. This article is an attempt to bring all the major findings of the recent relevant studies together, identify research gaps in the current state of knowledge on the utilization of SCMs in structural mortar, and give several recommendations for further study. The available results from recent studies have been reviewed, analyzed, and summarized in this article. A collection of the updated experimental findings will encourage and ease the use of various by-products and wastes as SCMs in structural mortar for sustainable construction.

“…The widest use of fly ash is in the production of cement because it exhibits pozzolanic properties [3,4]. Most international and domestic research is based on the use of fly ash as a substitute for cement in concrete production [5][6][7][8]. Mohanty and Patra [9] conducted dynamic testing for construction of embankments made of fly ash.…”

Physico-mechanical properties of fly ash applicable in road constructionAn experimental research of physico-mechanical properties of fly ash and ash stabilized with lime and cement, as used in road construction, is presented in the paper. The binder was added in the proportion of 2, 4 and 6 % of the total quantity of fly ash. The testing revealed that ash samples with and without binder can be used for improvement of foundation soil and for construction of embankments and subgrade layers, but are not recommended for construction of subbase and base courses. The research is based on the use of fly ash for road construction, i.e. as a substitute for natural materials in construction industry, as this use would save natural resources whose reserves are limited. Fizikalno-mehanička svojstva letećeg pepela primjenjivog pri građenju cesta U radu je prikazano eksperimentalno istraživanje fizikalno-mehaničkih svojstava letećeg pepela i stabiliziranog pepela s dodatkom vapna i cementa primjenjivog za gradnju cesta. Vezivo je dodavano sa 2, 4 i 6 % u odnosu na ukupnu količinu letećeg pepela. Nakon izvršenih ispitivanja uočljivo je da uzorci pepela bez dodataka i s dodatkom veziva mogu koristiti za izradu temeljnog tla, nasipa i posteljice, dok za izradu nosivih slojeva nisu preporučljivi. Istraživanje se temelji na korištenju letećeg pepela za izgradnju cesta, odnosno kao zamjena prirodnim materijalima u građevinarstvu, pri čemu se štede prirodni resursi čije su rezerve ograničene.
