The main component of OPC and the material that gives it strength, clinker, is produced by sintering a well-defined raw meal made of limestone mixed with one or …
Although Ordinary Portland cement (OPC) concrete is the most widely used construction material in the world, it is responsible for around 5–7% of the world's total CO2 production. Recently, Geopolymer concrete (GPC) has become a popular construction material since it is significantly more environmentally friendly than OPC concrete. …
The principal raw materials used in the manufacture of Ordinary Portland Cement are: Argillaceous or silicates of alumina in …
However, Sagoe-Crentsil et al. [169] reported that the geopolymer concrete shows 10-fold higher water permeability (1.52 × 10-10 m/s) compared to the OPC concrete (1.73 × 10-11 m/s). So, the permeability of geopolymers scattered a lot due to different test methods and materials used.
Among all the raw materials, limestone is the majorly consumed material with its share of about 70%, and this is the reason why cement plants are situated at a close proximity to the quarry sites to minimize the transportations distances and hence reduction in fuel consumption for transporting this important raw material. Since all the …
