Summary: Using supplementary cementitious materials (SCMs) as cement substitutes is an effective solution for producing eco-friendly concrete and preserving the environment from emissions related to cement manufacture. However, the addition of ground granulated blast furnace slag (GGBFS) and fly ash (FA) as substitutes has a negative impact on the shear behavior and mechanical characteristics of self-compacting concrete (SCC) beams.

Summary: This study investigated the influence of fly ash and ground granulated blast furnace slag on the capacity and reliability of Raman spectroscopy in establishing the carbonation profile in concrete blends. The results showed that while Raman spectroscopy was effective in differentiating CaCO3 contents in FA or GGBS blends, the incorporation of these SCMs into the PC system had negative effects on the quantification of CaCO3.

Summary: This paper studied the workability, mechanical properties, and hydration characteristics of alkali-activated phosphorus slag-granulated blast furnace slag (AAPG) by mixing phosphorus slag with granulated blast furnace slag. The results showed that the addition of granulated blast furnace slag improved the fluidity and early strength of AAPG, but excessive content led to flash setting of the slurry. The hydration products of AAPG were mainly C-S-H and C-(N)-A-S-H, with some hydrotalcite by-products, but exhibited uneven distribution.

Summary: The cement industry is facing a serious challenge in reducing carbon emissions. This study used mineral admixtures to replace partial cement in order to lower CO2 emissions. Experimental results showed that the higher the content of supplementary cementitious materials (SCMs), the lower the compressive strength, ultrasonic pulse velocity, cumulative heat of hydration, and carbon emissions of the mixed paste, while the surface resistivity increased. The quaternary mixed paste demonstrated high durability and sustainability, with wide application prospects.

Summary: In this study, the influence of carbonation on the frost resistance and pore structure of blast furnace slag concrete was investigated. The results showed that the carbonation speed is closely related to the 28-day compressive strength of the concrete. The frost resistance, carbonation resistance and scaling resistance of blast furnace slag concrete decrease as the replacement ratio of blast furnace slag increases. Moreover, carbonation affects the pore volume and structure of the concrete.

Summary: The increasing concerns about environmental contamination have raised the need for a better understanding of carbon dioxide emissions. The impact of economic activities and global population growth has negatively affected the environment. This study focuses on reducing carbon dioxide emissions in the construction industry through the use of sustainable materials. The research shows that the compressibility behavior of kaolin clay treated with ground granulated blast furnace slag (GGBS) improves with higher GGBS content and longer curing time. It also reveals that carbonation enhances the compressibility features of kaolin clay.

Summary: The study investigates the effects of limestone powder on various aspects of alkali-activated cements, including rheological behavior, pore solution chemistry, mechanical properties, and microstructure. It was found that limestone powder enhances the structural build-up and reaction rate of the mixtures. However, the inert character of limestone powder leads to a decrease in compressive strength of the ternary mixtures.

Summary: This study focused on preparing blast furnace slag (BFS) as a denitration catalyst, and investigated the effect of alkalinity on denitrification performance after modifying BFS with different alkaline and acidic oxides. The results showed that alkaline oxides modification improved denitration performance by generating -OH, while acidic oxides modification absorbed f-CaO in the slag and did not enhance denitrification. Increasing alkalinity of modified GGBS led to improved denitration performance.

Summary: This study investigated the hypothesis that higher concentrations of natural radionuclides, harmful to human health, may be present in self-compacting concretes (SCCs) due to its higher powder material content compared to conventional concretes. The findings showed that adding fly ash, silica fume, and ground granulated blast furnace slag can increase the compressive strength of SCCs. Fly ash exceeded the limit for structural material, while silica fume proved to be an effective material in reducing concrete radioactivity.

Summary: In recent years, there has been significant interest in alkali activated and blended cements worldwide due to their advantages of low energy costs, high strength, and good durability. This study evaluated the effects of replacing 50% of Portland cement with a mixture of waste materials and different alkali activators on the performance of the cement. The results showed that different alkali activators had varying effects on the strength and hydration products formation, while the addition of fly ash, slag, and geothermal waste had positive impacts on strength and densification of the cement matrix.

Summary: This study systematically investigated the hydration and rheological behavior of ultra-fine ground granulated blast furnace slag (activated-BFS) with carbide slag and anhydrous phosphogypsum (AG) as combined activators. The results showed that the type of BFS played a limiting role in setting time, and their rheological behavior fitted with H-B model.

Summary: Self-compacting geopolymer concrete (SCGC) is an eco-efficient and sustainable concrete that has a lower carbon footprint than conventional concrete. The dosing levels of metakaolin (MK), fly ash (FA), and ground granulated blast furnace slag (GGBFS) have an effect on the properties of SCGC, with MK and GGBFS reducing flowability and increasing compressive strength. GGBFS has a positive effect on the early mechanical properties of SCGC, with a higher CaO content resulting in a denser matrix structure and better mechanical properties.
