“…In fact, for each ton of clinker produced, approximately 800 kg of CO 2 is concomitantly produced, which means that the production of one ton of cement may result in the release of up to 540 kg of CO 2 into the atmosphere [ 10 , 11 ]. These CO 2 emissions result from two main sources: CO 2 process emissions (CPEs) and CO 2 energy emissions (CEEs).…”

Because of the severe environmental impact of the CO2 emissions associated with the production of ordinary Portland cement (OPC) and the increasing demand for this commodity material, the development of alternative products has become a global concern. One alternative to OPC, or alitic-based clinkers, are amorphous-wollastonitic low-calcium hydraulic binders (AWLCs). This new class of hydraulic binders, described in the literature for the first time in 2015, may significantly reduce the CO2 emissions associated with its production, resulting from its lower calcium content, but also from the fact that its production technology can be fully electrified. In this paper, a state-of-the-art review is presented, providing a comprehensive description of the latest research, summarizing both the physicochemical and mechanical characteristics of this type of hydraulic binder, as well as possible routes for its production at an industrial scale.

“…Unfortunately, 1 ton of OPC production emits an almost equal quantity of CO 2 into the environment [4]. In simple statistics, "more is the production of OPC, more will be the emissions of CO 2 , and at the same time, more will be the degradation of confined natural resources" [5][6][7][8]. By and large, CO 2 emissions alone are answerable for 65% of global warming, out of which OPC production is single-handedly accountable for roughly 6% of the total emissions of carbon dioxide [9].…”

The discovery of an innovative category of inorganic geopolymer composites has generated extensive scientific attention and the kaleidoscopic development of their applications. The escalating concerns over global warming owing to emissions of carbon dioxide (CO2), a primary greenhouse gas, from the ordinary Portland cement industry, may hopefully be mitigated by the development of geopolymer construction composites with a lower carbon footprint. The current manuscript comprehensively reviews the rheological, strength and durability properties of geopolymer composites, along with shedding light on their recent key advancements viz., micro-structures, state-of-the-art applications such as the immobilization of toxic or radioactive wastes, digital geopolymer concrete, 3D-printed fly ash-based geopolymers, hot-pressed and foam geopolymers, etc. They have a crystal-clear role to play in offering a sustainable prospect to the construction industry, as part of the accessible toolkit of building materials—binders, cements, mortars, concretes, etc. Consequently, the present scientometric review manuscript is grist for the mill and aims to contribute as a single key note document assessing exhaustive research findings for establishing the viability of fly ash-based geopolymer composites as the most promising, durable, sustainable, affordable, user and eco-benevolent building materials for the future.

A novel process is reported that produces amorphous silica and nesquehonite (MgCO 3 ·3H 2 O) from the magnesium silicate mineral olivine ((Mg, Fe) 2 ·SiO 4 ). The amorphous silica forms a supplementary cementitious material for use in concrete. The formation of nesquehonite sequesters carbon making the overall process carbon negative. Nesquehonite can also be used to form low-carbon construction products such as bricks, blocks and boards. This article reports on key process optimization studies. The potential for amorphous precipitated silica derived from olivine to produce carbon-negative concrete is discussed.
