Characteristics of Kedondong Trass and Bobos Trass as Cement Raw Material, Cirebon, West Java, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2022
The use of cement materials in construction continues to increase every year, consumes lots of raw material and emits CO2 from clinker production. To eliminate this negative effect, alternative materials are needed.

The effect of supplementary cementitious materials on transport properties of cementitious materials - state-of-the-art

Concrete Structures, 2021
The supplementary cementitious materials (SCMs) have recognized many of the beneficial influences on concrete ability to resist the penetration of chloride ions, such as fly ash, slag, silica fume, metakaolin, and other natural pozzolans; this benefit has primarily been ascribed to the refined pore structure that results from the appropriate use of ...

BAP31 Drives Cartilage Calcification through Disruption of Autophagosome–Lysosome Fusion in Osteoarthritis

Advanced Science, EarlyView.
Mechanical stress activates BAP31 in chondrocytes. BAP31 competes with ATG14 for binding to STX17, disrupting the STX17–ATG14 complex required for autophagosome–lysosome fusion. The resultant autophagic flux blockade drives the generation of autophagy‐derived exosomes, which mediate pathological cartilage calcification in OA. Chondrocyte‐targeted BAP31

Feasibility of Non-Remanufactured Waste Bottle Glass as Supplementary Cementitious Material

Applied Sciences
Theoretically, glass can be recycled entirely, but there are several requirements for remanufacturing. For the first time, this work studied industrial bottle waste glass (WG), which cannot be used to remanufacture new glass as a cement replacement for ...

Examining the pozzolanicity of supplementary cementitious materials using isothermal calorimetry and thermogravimetric analysis

, 2017
It has recently been proposed that the pozzolanicity of supplementary cementitious materials can be determined by monitoring the heat released when supplementary cementitious materials are mixed with calcium hydroxide at high temperature and high pH.
