Magnesium silicate hydrate (M-S-H) gel is formed by the reaction of brucite with amorphous silica during sulphate attack in concrete and M-S-H therefore regarded as having limited cementing properties. The aim this work was to form pastes, characterise hydration reactions assess resulting It shown that pastes can be prepared reacting magnesium oxide (MgO) fume (SF) at low water solid ratio using sodium hexametaphosphate (NaHMP) a dispersant. Characterisation x-ray diffraction...
Ambient temperature drying shrinkage in metakaolin‐based geopolymer pastes exposed to low relative humidity environments has been investigated. The effect of varying the composition (water content, Si : Al ratio, Na and + or K cations) on sensitivity ambient is reported. definition “structural” water as being minimum content required that prevents contractions gel structure, thus from occurring, introduced. From results presented, it clear ionic charge density cations, total quantity...
Various measures can be employed to decarbonise cement production, including clinker substitution, alternative fuels, kiln improvements, and carbon capture storage. In this study, we quantify the CO2-eq. emissions mitigation potentials of these on typical production in Europe until 2050 using prospective life cycle assessment, influence possible futures socioeconomic development. We combined environmental product declaration data for with a modified inventory database (based ecoinvent v.3.6)...

In low- and middle-income developing countries, the informal (collection and) recycling sector (here abbreviated IRS) is an important, but often unrecognised, part of a city’s solid waste resources management system. Recent evidence shows rates 20–30% achieved by IRS systems, reducing collection disposal costs. They play vital role in value chain reprocessing into secondary raw materials, providing livelihood to around 0.5% urban populations. However, persisting factual perceived problems...
