Section snippets Clinker preparation. Waste sludge and steel slag can be recycled as a partial replacement for the raw materials of cement. A hydraulic type of cement (referred to as eco-cement) was produced using different types of sludge ash, including those from sewage water treatment, water works, and aluminum-containing …
Concrete is the most common building material around the world [2], and it consists primarily of Ordinary Portland Cement, a widespread type of cement that has been used in the construction sector ...
The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry's CO 2 emissions are caused by transformation of limestone into lime, called "decarbonation". Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone …
The materials employed were dried sewage sludge (from a wastewater treatment plant sited in Tarragona, Spain) and milled cement raw material (CRM), both supplied by a cement industry close to our University. An exhaustive analysis of the two materials was carried out, and the results are shown in Table 1.
This study applied Life Cycle Assessment (LCA) methodology to investigate the environmental impact of cement production and explore environmental …
Marble sludge waste was used as a major cement raw material in sintering sulfoaluminate cement clinker successfully in the laboratory. The influences of raw mix composition as well as different burning temperatures were investigated.
However, a high cost is the main obstacle to the application of CŜAB cement, since it makes use of expensive bauxite ores as raw material for aluminium source. In order to reduce cost, industrial wastes, such as marble sludge waste, AS, PG, electrolytic manganese residue and so on, are used for synthesis of this kind of cement, …
