Summary: Using RAP material with stabilizer can effectively solve new material issues, reduce haulage distance, and save fuel costs. A mixed design of the CTB layer was formulated to make maximum use of RAP material in a sustainable way, and the mechanical and durability properties were evaluated through laboratory tests. The optimal mix was determined based on the Unconfined Compressive Strength (UCS) value and flexural strength, and the durability properties were analyzed through various tests. The results showed that using 70% RAP with stabilizer leads to a strong and durable CTB mix.

Summary: This study investigates the use of ferrochrome slag (FCS) as a replacement for Portland cement (PC) in cement composites. It was found that incorporating FCS as partial replacement of PC led to longer set times, lower water content, decreased compressive strength, improved durability, and resistance to acid attack. Microstructural analysis revealed an increase in the formation of calcium silicate hydrate when using FCS as a replacement for PC, resulting in a denser microstructure. Leaching tests showed that the Cr leaching values of FCS were within permissible limits, making it suitable for general construction applications.

Summary: This study investigated the effects of hydroxypropyl methylcellulose (HPMC) and silica fume (SF) doping on the stability, rheological properties, and printability of 3D printing foam concrete. The addition of HPMC and SF effectively reduced volume bleeding rate, stabilized foam, and increased wet density. The static yield stress, dynamic yield stress, and plastic viscosity of foam concrete increased continuously with higher dosages of HPMC and SF.SF significantly increased the static yield stress, while HPMC significantly affected the dynamic yield stress and plastic viscosity. The study proposed combining tan theta and stack height to evaluate buildability and provided suitable ranges for key parameters for printable foam concrete. The compressive strength of printed foam concrete reached high values in different directions.

Summary: Understanding the size effect of UHPC under compression is essential for design and analysis purposes. This study investigated the size effect of UHPC cubes through variations in steel fiber content and water-to-binder ratios. The results indicate that the compressive strength size effect of UHPC increases with an increase in short straight fiber content, but decreases with an increase in water-to-binder ratio. UHPC with short hooked fiber exhibits the largest size effect, while UHPC with long hooked fiber shows the smallest size effect. The Bazant size effect law is a more reliable predictor of the change in UHPC compressive strength with specimen size.

Summary: This study investigates the long-term volume stability and strength development of engineered cementitious composites (ECC) containing high-volume steel slag (SS). It is found that the strength of ECC with SS starts to decline after 90 days, while the decline is more significant compared to the matrix. The expansion of SS reduces the fracture toughness of the matrix, leading to an increase in toughness and ductility of the ECC. The introduction of ground granulated blast furnace slag (GGBFS) and PVA fibers can reduce the volume expansion and strength loss caused by SS expansion.

Summary: This study investigated the leaching rate of Ca2+ from magnesium slag (MS) and developed a leaching-carbonation method to convert MS into high-purity vaterite and supplementary cementitious materials. The wet carbonation process with glycine as a crystal modifier successfully produced spherical vaterite with high purity and surface area. The leachate solid residue (LSR) obtained from the leaching process of MS showed a smaller size destruction and higher surface area compared to Portland cement, leading to accelerated hydration process and improved compressive strength and pore structure development. This work provides a novel treatment method for MS and enables its high value-added utilization.

It was found that both dosages of DEIPA and EDIPA promote the chemical effect of limestone and the hydration of aluminates from cement and fly ash. The hydration of silicates was accelerated by 0.02% of DEIPA or EDIPA but delayed by 0.05% due to excessive aluminates hydration. DEIPA and EDIPA also refine the pore structure and increase compressive strength of the blend mortar.

Summary: This review paper provides an overview of internal curing mechanism, common internal curing agents, and the most promising agent-superabsorbent polymers in alkali-activated materials (AAM) systems. The introduction of voids by internal curing agents typically has a negative impact on mechanical properties, but continuous water release during internal curing counteracts this effect by promoting hydration. While the effect of internal curing in reducing autogenous shrinkage of AAM systems has been well-established, the impact on drying shrinkage varies widely in different studies.
