How to Make Alternatives to Portland Cement

Lime-pozzolana cement by itself can make an excellent cementing material for low-rise construction or mass concrete and in some countries (e.g. Indonesia) is still produced extensively. Pozzolanas can also be mixed with lime and/or Portland cement at the construction site but care must be taken to ensure the pozzolana is of a consistent quality and that the materials are thoroughly mixed.

Cement

· Cement Cement History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.
