Mortar is produced by mixing a binding material (cement or lime) with fine aggregate (sand, surki, etc) with water. On average, Type I cement (C3A = 9.5 percent) performed 1.7 times better than Type V cement (C3A = 2.8 percent) in terms of time of initiation of … Types of Cement The properties of cement during hydration vary according to: • Chemical composition • Degree of fineness It is possible to manufacture different types of cement by changing the percentages of their raw materials. THE CEMENT MANUFACTURING PROCESS Prof. Dr Elshafie Ahmed Gad Faculty of Applied Science Chemistry Dept. Its quality is that it set into a stone-like mass within a period of fewer than 30 minutes. The usual water cement ratio is 45% (5.2 gal/sack) of dry cement; 500 gal per cementing unit should be provided for priming, testing, and cleaning up. Types of Cement "31cement is about 25 per cent higher than that of rapid hardening cement at one or two days and 10–20 per cent higher at 7 days. Depending upon the materials used for mortar mixture Usually, 0.5 to 1.0 mm diameter steel wires are formed into meshes. Alibaba.com offers 1,113 types of cement pdf products.
