Raw Mix Design by Rashid Jamal (16.02.2017) | PDF | Cement …

The document discusses raw mix design for cement manufacturing. It defines raw mix as a mixture of materials that will react together to form the calcium silicates in clinker which give cement its strength. There are several factors that influence cement quality and production costs. The raw mix needs to be optimized to ensure trouble-free operations, maximize efficiency while …
