Fat lime is produced from sea shell, coral deposits etc or from lime stone containing impurities like free sand and soluble silica combined with alumina, magnesium, carbonate etc. If the proportion of free sand is large, the resulting lime becomes progressively poor and is called poor or lean lime. Fat lime slakes rapidly when water is added giving out considerable

Feebly hydraulic lime contains less than 15% of silic and alumina. It slakes slowly. The expansion on slaking is small. It produces good mortar. Moderately hydraulic lime: It contains 15-25% of silica and alumina, slakes slowly with small expansion and is stronger than feeble type. It is suitable for good class of mortar, brick work and masonry. c. Eminently hydraulic

Hydraulic lime is obtained from limestone or kankar, containing a very small %age of free sand and soluble silica combined with 10-39% of clay and magnesium carbonate. It also contains CaCO3. These components impart the property of Hydraulicity to lime. Hydraulic lime slakes very slowly (sometimes taking several hours even days to do so) without producing

Technical writing is an important part of everyone's career. Writing well is difficult and time consuming and writing in a technical way about technical subjects even makes it more difficult. People write to propose projects, to document their own actions, to help other understand the research, to analyze and solve problems, to describe procedures and objects. If done well

A tech. report can be used for the physical description of a new machine, the steps in a particular process, or the results of an experiment. For example; A writer not only describes two sites for a factory but also persuades readers to accept one of them as the best i.e. to prove your point. The document that achieves these purposes is called technical writing.
