This paper investigates on the mechanical characteristics (compressibility and shear strength) of fly ash/ground-granulated blast-furnace slag (GGBS) mixtures at various mix ratios using consolidation direct tests, respectively. The studies were done a reduced duration load increment. compressibility behaviour has been found to improve with increase in GGBS content. Direct test results showed a...

In situ X-ray Micro-Tomography (XMT) analyses with a pixel size of 0.325 µm were conducted on slag-based blended cements containing 75% Ground-Granulated Blast-Furnace Slags (GGBS) and 25% Ordinary Portland Cement (OPC), or without CaCl2 acceleration. Results show the identification main cementitious phases need to perform data repeatability tests in order allow their quantification. Investigat...

Abstract The purpose of this study was to evaluate the possibility using ground waste-expanded perlite (WP) as a sustainable replacement for granulated blast-furnace slag (GGBFS) precursor in alkali-activated systems. nature and amount hydration products, microstructure, compressive strength development were investigated mixtures where GGBFS substituted with 10, 20 40% by weight WP activated tw...

Abstract An attempt to shed light on the use of agro-industrial-based wastes as supplementary cementitious material (SCM) or alkali-activated binder (AAB) is mainly focused in this review paper. The SCM AAB acts a suitable replacement for cement, cement manufacturing tends contribute 8–10% global CO 2 emissions. To gain acceptability construction industry, diverse must demonstrate their potenti...

This paper aims at bringing a literature review on the uses and properties of popular industrial and mineral byproduct slag. At the present, most industrial slags are being used without taking full advantage of their properties or disposed rather than used. The use of slag in replacing Portland cement by GGBFS is not very common. The traditional way to utilize metallurgical slags in cementing m...

This paper studied the influence of modulus and dosage sodium silicate on hydration alkali-activated copper-nickel slag (CNS) materials. CNS was used as main raw material, ground granulated blast furnace (GBFS) powder selected mineral additive. The hardening mechanisms were discussed. experimental results showed that [SiO4]4− [AlO4]5− with a high degree polymerization in glassy phase more easil...
