The Wet Process and The Dry Process. From the earliest times, two different methods of rawmix preparation were used: the mineral components were either dry-ground to form a flour-like powder, or were wet-ground with added water to produce a fine slurry with the consistency of paint, and with a typical water content of 40–45%.
Dry pour concrete, also known as dry mix concrete, involves a simpler preparation process. The composition typically includes cement, sand, and aggregates, which are combined without water initially. This mixture is then applied to the desired area, and water is added subsequently to activate the cement and initiate the curing process.

In the subsequent half century, efficient dry process kilns have almost completely displaced slurry-fed kilns. The pioneering was done by Blue Circle, who had eight dry process kilns in operation before the start-up of Tunnel's Padeswood A3 in 1966. The types of dry process kilns fall roughly into four categories:
Fig: Manufacture of Cement by Dry Process. b) Wet Process The raw materials are firstly crushed and made into powdered form and stored in silos. The clay is then washed in washing mills to remove adhering organic matters found in clay. The powdered limestone and water washed clay are sent to flow in the channels and transfer to grinding mills ...
The processes of making cement by both the dry process and wet process are shown in Fig. 5.1. In raw meal preparation for dry process cement manufacture, the raw materials are subjected to crushing in an appropriate plant, dried and ground to a fine powder. In the wet process, hard material such as limestone and marl are subjected to ...
In this paper we are discussing wet and dry process of Portland cement manufacture. Wet process minerals are wet ground to form a slurry and in dry process minerals are dry ground to form a powder like substance. In this paper, we are discussing the comparison between wet process and dry process with various advantages and disadvantages.
The two basic methods for applying shotcrete are the dry-mix process and the wet-mix process. The term gunite is frequently used when referring to the dry-mix method; other terms such as air-placed concrete, gunned concrete and sprayed concrete have also been used in the past to describe the process.
