In this research, RP was prepared from hardened cement paste by wet grinding (i.e. WGRP) in the laboratory, and an attempt to utilize these nano particles as an accelerator for facilitating Portland cement (PC) hydration was done. The basic properties of WGRP were characterized, and the effect of WGRP on the properties of PC was …
In present work, sulphoaluminate cement (SAC) and Portland cement (PC) paste were considered, and 0 ∼ 5 % nano-ettringite prepared by hydration-wet grinding method was extra incorporated. The ...
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the …
The following are the major advantages of the Wet Process of Cement Manufacturing, Raw material can be mixed easily, so a better homogeneous material can be obtained. Capital cost (Cost of establishment) is comparatively less. Disadvantages. The following are the major disadvantages of the wet process of cement manufacturing,
