“…Around 60-130 kg of fuel oil or its equivalent and about 110 KW-h of electricity are required to produce one metric ton of cement, depending on the cement type and the processes used [6]. Approximately, 800-1000 kg of CO 2 emissions occur during the production of each ton of cement [3,7,8]. About 5%-8% of the global man-made emissions of CO 2 is caused by cement production [3,5,[8][9][10].…”

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.

“…As biomass ashes have similar properties to fly ashes coming from coal combustion, their applicability as supplementary cementitious materials has been increasingly studied in recent years [46]. An overwhelming majority of reported studies was aimed at the use of biomass ash in PC-based blends [47,48,49]. These papers reported on proper chemical and mineralogical composition of different types of biomass ashes, their high specific surface, particle size distribution similar to that of cement, and high pozzolanity.…”

Influence of Wood-Based Biomass Ash Admixing on the Structural, Mechanical, Hygric, and Thermal Properties of Air Lime Mortars

Mechanically-activated wood-based biomass ash (WBA) was studied as a potential active admixture for design of a novel lime-pozzolan-based mortar for renovation purposes. The replacement ratio of lime hydrate in a mortar mix composition was 5%, 10%, and 15% by mass. The water/binder ratio and the sand/binder ratio were kept constant for all examined mortar mixes. Both binder constituents were characterized by their powder density, specific density, BET (Brunauer–Emmett–Teller), and Blaine specific surfaces. Their chemical composition was measured by X-ray fluorescence analysis (XRF) and mineralogical analysis was performed using X-ray diffraction (XRD). Morphology of WBA was investigated by scanning electron microscopy (SEM) and element mapping was performed using an energy dispersive spectroscopy (EDS) analyzer. The pozzolanic activity of WBA was tested by the Chapelle test and assessment of the Portlandite content used simultaneous thermal analysis (STA). For the hardened mortar samples, a complete set of structural, mechanical, hygric, and thermal parameters was experimentally determined. The mortars with WBA admixing yielded similar or better functional properties than those obtained for traditional pure lime-based plaster, pointing to their presumed application as rendering and walling renovation mortars. As the Chapelle test, STA, and mechanical test proved high pozzolanity of WBA, it was classified as an alternative eco-efficient low-cost pozzolan for use in lime blend-based building materials. The savings in CO2 emissions and energy by the use of WBA as a partial lime hydrate substitute in mortar composition were also highly appreciated with respect to the sustainability of the construction industry.

One of the possible solutions for reducing the environmental impact of concrete industry represents the application of supplementary cementitious materials (SCM) [1]. The presence of such materials influences the amount and type of hydrates formed in blended cement systems as well as their volume, porosity and finally the durability of the cement-based composites [3].…”

One of the possible solutions for reducing the environmental impact of concrete industry represents the utilization of the supplementary cementitious materials. For that purpose some of the alternative materials from Serbia, such as biomass ash, fly ash and natural zeolite, are characterizated, their class of pozzolanic activity and activity index are determined and presented in this paper. Based on those results, it can be concluded that this characterized materials can be used as supplementary cementitious materials in the cement composites.
