Investigation of using recycled powder from the preparation of recycled aggregate as a supplementary cementitious material

Shujun Li et al.

Summary: The study investigates the properties of recycled concrete powder (RCP) and recycled brick powder (RBP) and their impact on mortar properties. It was found that RBP has a lower negative impact on mortar workability compared to RCP due to its lower specific surface area and porosity, and contributes significantly to flexural strength.

Effect of wet grinded lithium slag on compressive strength and hydration of sulphoaluminate cement system

Hongbo Tan et al.

Summary: A new approach was proposed to utilize nano lithium slag (nano-LS) to improve the early compressive strength of sulphoaluminate cement (SAC) in this study. The results showed that nano-LS significantly promoted the compressive strength and hydration process of SAC, demonstrating the excellent application potential of LS in the cement system.

Nano particles prepared from hardened cement paste by wet grinding and its utilization as an accelerator in Portland cement

Junjie Zhang et al.

Summary: In this study, recycled powder (RP) was successfully prepared from hardened cement paste with a median particle size of 249 nm, and it was proven to act as an accelerator for facilitating Portland cement (PC) hydration. The addition of WGRP accelerated the setting process of PC pastes, significantly increased the early strength and impermeability of PC mortars.

Utilization of barium slag to improve chloride-binding ability of cement-based material

Pian Chen et al.

Summary: The study found that adding 10-30% of barium slag (BS) significantly increased the chloride-binding ability of the cement-BS system. This was mainly due to the optimized pore structures, facilitation of the formation of Friedel's salt in hardened pastes, and reduction of physically adsorbed chloride ions.

Effect of high-energy milling on the structure, some physicochemical and photocatalytic properties of clinoptilolite

V Sydorchuk et al.

Summary: The Natural and H-form of clinoptilolite were mechanochemically treated in water and air, leading to improved photocatalytic activity in the process of rhodamine B degradation under visible light. The study also found that milling in water partially maintained the crystalline structure with a meso-macroporous structure formed in both cases.

Hydration and mechanical properties of cement-marble powder system incorporating triisopropanolamine

Jie Wang et al.

Summary: The incorporation of triisopropanolamine (TIPA) enhanced the mechanical strength and capillary water absorption of cement-marble powder (MP) mortar, with the improvement of these properties observed when the TIPA dosage exceeded 0.06%. The acceleration effect of TIPA on the cement-MP system hydration process was found to be the main reason for the enhancement of these properties.

Low carbon cementitious materials: Sodium sulfate activated ultrafine slag/fly ash blends at ambient temperature

Junjie Zhang et al.

Summary: Na2SO4 (NS)-activated slag as an alkali-activated binder showed slower strength development but lower CO2 emissions potential compared to NaOH and water glass. By using ultra-fine slag and fly ash (FA), the compressive strength was improved while reducing CO2 emissions. The study indicated a promising low carbon alkali-activated binder.

Proposal of demolished concrete recycling system based on performance evaluation of inorganic building materials manufactured from waste concrete powder

Dayoung Oh et al.

Summary: The rapid industrial development and global population growth of the past century have led to an exponential increase in resource consumption and CO2 emissions, resulting in global warming and related environmental issues. Recycling waste concrete to produce added-value inorganic building materials such as recycled cement can help reduce construction waste and prevent resource depletion.

Compressive strength development and durability properties of high volume slag and slag-fly ash blended concretes containing nano-CaCO3

Anwar Hosan et al.

Summary: The study demonstrated that the addition of 1% nano-CaCO3 greatly improved the compressive strengths and durability properties of high volume slag (HVS) and high volume slag-fly ash (HVS-FA) blended concretes. The inclusion of 1% NC not only enhanced compressive strengths, but also reduced water sorptivity, controlled volume of permeable voids, minimized drying shrinkage strain, and significantly improved resistance against chloride ion penetration. Furthermore, SEM and EDS analysis revealed a denser microstructure of paste and interfacial transition zone (ITZ) around aggregates in NC-modified concretes.

Mineralogical and microstructural alterations in a portland cement paste after an accelerated decalcification process

I Garcia-Lodeiro et al.

Summary: This study analyzed the microstructural changes in cement pastes exposed to accelerated decalcification, revealing significant effects on portlandite, C-S-H gel, anhydrous clinker, and ettringite. Decalcification induced major micro- and nano-structural changes, particularly in the layers closest to the leaching agent. The distribution of water molecules and the type of bonding in different layers were also found to be significantly affected by the decalcification process.

Action of the combined presence of C-S-Hs-PCE and triethanolamine on the performances of cement paste/mortar

Chao Xu et al.

Summary: The addition of 0.02% TEA and 0.5-2% C-S-Hs-PCE enhances compressive strengths of cement mortar, promotes C3S hydration, and reduces pore quantity and volume; whereas the composite addition of 0.5%-1% TEA and 0.5%-2% C-S-Hs-PCE decreases compressive strengths and increases pore quantity.

Effect of chloride attack on the bonded concrete system repaired by UHPC

Qing Chen et al.

Summary: The study found that under chloride attack, the compressive and bonding strength of UHPC repaired systems decrease, along with a reduction in flexural performance. Electrochemical behavior and microstructural analysis indicate that the UHPC layer has better resistance to chloride attack compared to the matrix layer.
