This article evaluates the ability of a magnesia kiln dust (PC-8) and commercial calcined MgO (MCB100), combined with ground granulated blastfurnace slag (GGBS), as constituents binary M-S-H binders. Mortars pastes were manufactured their properties compared to those Portland Cement (PC). MgO-based mortars showed an increase in setting time higher fresh consistency. At earlier ages lower mechan...

In the last few decades, concrete industry has been massively expanded with adoption of various kinds binding materials. As a substitute to cement and in an effort relieve ecofriendly difficulties linked creation, utilization industrial waste as cementitious material can sharply reduce amount trash disposed lakes landfills. With respect mechanical properties, durability thermal behavior, ground...

A lot of energy is released during the cement manufacturing process, and a large amount carbon dioxide (CO2) discharged into environment. Presently, researchers are focusing on reducing CO2 emissions by researching sustainable alternatives to traditional Portland cement-based materials. comparative study material characterization both calcined agro-based waste ash (calcined ash) uncalcined (unc...

塩基度が1.63から1.90の3種の高炉スラグ微粉末（GGBS）を用いて、10、20、および30℃における高炉セメントの強度発現性を評価するとともに、水和生成物の定量、C-S-Hの化学組成分析、空隙径分布の定量などの水和解析を実施した。塩基度が低いGGBSを用いたセメントは、温度が高く材齢が長期になるほど塩基度の高いGGBSとの強度の差は小さくなり、環境温度が強度発現性に及ぼす影響が大きかった。塩基度の低いGGBSを用いたセメントペーストは、水和物全体に占めるC-S-Hの割合が多く、C-S-Hの生成が強度増進に大きく寄与したことが推察された。

In an attempt to increase sustainability of construction materials, both ground granulated blast-furnace slag (GGBS) and, less popular, copper (CS) can be used in alkali-activated composites. However, such composites are often more susceptible cracking, triggered by the self-desiccation processes. The addition superabsorbent polymers (SAP) may enable internal curing concrete and prevent excessi...

Geopolymer concrete, because of its less embodied energy as compared to conventional cement has paved the way for achieving sustainable development goals. In this study, an effort was made optimize quality characteristics or responses, namely, workability, and compressive flexural strengths Ground Granulated Blast-furnace Slag (GGBS)-based geopolymer concrete incorporated with polypropylene (PP...
