Cement history. Throughout history, cementing materials have played a vital role and were used widely in the ancient world. The Egyptians used calcined gypsum as a cement and the Greeks and Romans used lime made by heating limestone and added sand to make mortar, with coarser stones for concrete.

They summed up these similar processes into unit operations. Each unit operation follows the same physical laws and may be used in all relevant chemical industries. For instance, the same engineering is required to design a mixer for either napalm or porridge, even if .

The usual water cement ratio is 45% ( gal/sack) of dry cement; 500 gal per cementing unit should be provided for priming, testing, and cleaning up. An additional 5130 gal should be provided as a minimum safety margin. Rate of water supply should be based on the rate of mixing cement: usually this is 56 bbl/min. for each pumping unit on the job.

Design and Control of Concrete Mixtures, 16th edition: Media Type: Print Every industry has one outstanding reference book, and for concrete it is Design and Control of Concrete Mixtures—the guide to applications, methods, and more than 90 years, the publication has been the cement and concrete industry''s primary reference on concrete technology.

These cement and concrete standards allow laboratories all over the world to test and evaluate concrete mixtures to ensure their strength and safety. These standards help to identify the various properties of concrete including strength, elasticity, hardness, and workability. List of cement standards and concrete standards developed by ASTM:
