Fig. 1 shows the typical view of kaolin. The main constituent, kaolinite is a hydrous aluminium silicate of approximate composition 2H 2 O·Al 2 O 3 ·2SiO …

India strengthened its position as the second largest cement producer in 2022, with the country's share of global production rising from 8% in 2021 to 9%. Over the longer-term, declining production in China is expected to be offset by production increases in Southeast Asia, Latin America and Africa to meet their development needs.

 — While critical to many aspects of the built environment, the high levels of demand for cement currently results in more than 7% of anthropogenic greenhouse gas (GHG) emissions. 8 The majority of the CO 2 emissions from cement production are from fossil resources (i.e., mineral or energy resources that are not renewable on a short time …

 — This paper reports on the utilization of recycled moso bamboo sawdust (BS) as a substitute in a new bio-based cementitious material. In order to improve the incompatibility between biomass and cement matrix, the study firstly investigated the effect of pretreatment methods on the BS. Cold water, hot water, and alkaline solution were …

 — Therefore, enhancing the manufacturing technology of cement plant for cleaner production is one of the resolutions to this issue. Approach of using industrial waste as supplementary cementitious material or cement free concrete also would reduce dependency on cement demand. Success in utilizing other alternative material which …

It is well known that cement production is not neutral for natural environment among others due to high CO2 emission. Different strategies of mitigation of negative environmental impact of its production are developed. One of the ways is utilization of supplementary cementitious materials (SCMs) in the manufacture of cement and concrete. Introduction …

 — The unique properties of CNFs make them ideal candidates for various applications in cementitious mixtures, ranging from enhancement of strength and durability of conventional concretes in normal and extreme conditions [83], production of new generation of concretes (e.g., new generation of UHPCs, and structural lightweight …

 — Cement production involves the combustion of fossil fuels and the calcination of limestone, leading to the release of large amounts ... technologies, exemplified by carbonation, play a vital role by capturing CO 2 emissions from cement plants and integrating them into cementitious materials, thereby reducing both emissions and …

 — Steel slag is a byproduct from either the conversion of iron to steel in a basic oxygen furnace, or the melting of scrap to make steel in an electric arc furnace. This paper reviews the production, processing, and characteristics of steel slag, and its ...

 — Concrete production utilizes cement as its major ingredient. Cement production is an important consumer of natural resources and energy.
