“…This enhancement is primarily based on not only the chemical and phase composition of GGBS, but also on its latent hydraulic. [61][62][63] On the other hand, according to the results reported by Radman and Joorabchi, 3 resistance against HCl solution attack from the viewpoint of mass loss when GO is incorporated in the samples is due to ameliorating the samples' capillary pores. 6 Hence, utilizing GGBS and GO simultaneously results in achieving higher resistance against acid environments based on the present research.…”

In recent decades, considering environmental issues, partial replacement of Portland cement with supplementary cementitious material (SCM), namely ground granulated blast furnace slag (GGBS), has been in the spotlight of research. On the other hand, carbon‐based nanomaterials, especially graphene oxide (GO), are recognized as an extraordinary additive with special characteristics that can be included in cementitious materials. In this research, the impact of GGBS on the mechanical properties and durability of GO‐modified mortars was investigated at 28 and 90 days. The results demonstrate that by increasing the content of GGBS, a decrease in the flexural and compressive strength compared to plain cement sample was seen. On the other hand, incorporation of GGBS and GO led to higher strength compared to GO‐cement mortar. Also, the compressive strength of the sample containing 20% GGBS and 0.03% GO was 38.7% higher than the plain cement sample at 90 days. On the other hand, adding GGBS to a GO‐reinforced sample resulted in a more durable specimen against chloride and acid environments. The sample made of 40% GGBS in GO‐modified mortar not only has the best efficiency in harsh environments but also has the lowest water absorption. This mortar improved the migration coefficient, mass loss in HCl solution, and initial sorptivity by 20.1%, 57.7%, and 37.1%, respectively. Moreover, the mentioned sample had a denser microstructure with smaller cracks compared to other samples, based on scanning electron microscope (SEM) images.

Cement is the one of the World's most significant manufactured material. 5% of the total release of CO2 to the atmosphere is caused during the manufacturing for cement in cement industries. In an effort to reduce anthropogenic CO2 emission and for the economic reasons by-products are used as cementitious materials. Reuse of a large amount of waste materials like fly ash, PJ ash, silica fume, are done in large extents in the manufacture of cement and cementitious products. Prosopis Juliflora Ash (PJA) is derived from the stem and roots of the PJ tree. In this paper the PJA sample is examined by using FTIR. The peak values from the FTIR test shows the functional groups present in the PJA sample and those functional groups are tabled. In this paper gives the clear view of using stem and roots of the PJ tree and make them as ecofriendly to environment.

“…The result of Shi et al [ 17 ] has shown the dosage of coral sand powder at less than 15% has a beneficial impact on early compressive strength and pore structure. The other SCMs including fly ash, granulated blast furnace slag (GBFS, also referred to slag), and silica fume have been broadly used in Portland cement to reduce the emission of carbon dioxide and enhance the chemical–physical properties and function of concrete by their pozzolanic reaction [ 18 , 19 , 20 ]. To build confidence on and optimize the use of coral sand powder (CSP), it is essential to understand the hydration and microstructure characteristics of Portland cement incorporated with coral sand powder, and whether the coral powder is comparable to Portland cement blended with other SCMs.…”

The utilization of coral waste is an economical way of using concrete in coastal and offshore constructions. Coral waste with more than 96% CaCO3 can be ground to fines and combined with supplementary cementitious materials (SCMs) such as fly ash, silica fume, granulated blast furnace slag in replacing Portland cement to promote the properties of cement concrete. The effects of coral sand powder (CSP) compared to limestone powder (LSP) blended with SCMs on hydration and microstructure of mortar were investigated. The result shows CSP has higher activity than LSP when participating in the chemical reaction. The chemical effect among CSP, SCMs, and ordinary Portland cement (OPC) results in the appearance of the third hydration peak, facilitating the production of carboaluminate. CSP-SCMs mortar has smaller interconnected pores on account of the porous character of CSP as well as the filler and chemical effect. The dilution effect of CSP leads to the reduction of compressive strength of OPC-CSP and OPC-CSP-SCMs mortars. The synergic effects of CSP with slag and silica fume facilitate the development of compressive strength and lead to a compacted isolation and transfer zone (ITZ) in mortar.
