2. warm water methods: (a) 1 to 3 hours after casting, the specimens are immersed in water at a temperature of (55 1 c) and cured for 20 hours 10 min. (b) the specimen are demoulded and cooled at 27 2 c for one hour before testing. the average correlation is shown in fig. 20.19 which is generally used for different concrete.
3. initial and final setting time of cement test. initial setting time gives an idea about how fast cement can start losing its plasticity and the final setting time of cement gives an idea about how much time cement takes to lose its full plasticity and gain some strength to resist pressure.. initial setting time of cement: it is the time elapsed between the moments that the water is added to.

Cement cement extraction and processing: raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. some deposits are mined by underground methods. softer rocks such as chalk and clay can be dug directly by excavators.
Cement in the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. cement used in construction is characterized as hydraulic or nonhydraulic. hydraulic cements (e.g., portland cement) harden because of hydration, chemical reactions.

Colored cement; question 2. differentiate dry process and wet process of manufacturing cement answer : lime stone and clay are ground to fine powder separately and are mixed together. water is added to make a thick paste which contains 14 of moisture.
Concrete may be placed underwater with the help of bottom dump buckets. the concrete is taken through the water in water tight bucket. on reaching the place of deposition the bottom of the bucket is made to open and the concrete is dumped. in this process certain amount of cement is washed away causing a reduction in strength of concrete.
Cement Boards 101 Global Cement
Above table 1: typical properties and applications of the different types of cement boards. figure 1 shows the division of cement board types being produced worldwide by 90 global manufacturers. fibre cement board, the oldest board type, has 43 global producers, while wood strand cement board (also known as eltoboard) has only six.
Fiber cement board are composed of cement, silica sand and wood pulp. reinforced fiber cement products such as fiber cement board are manufactured using the hatscheck process. the hatsheck process was initially developed for the production of asbestos composites, but it is now used for the manufacture of nonasbestos, cellulose fiber reinforced cement composites.
