Debunking the Egyptian pyramid cast concrete theory

Firing limestone at high temperatures produces "quicklime", a substance that when mixed with sand and water produces lime mortar suitable for use with brick construction. Lime mortar is not the same as concrete, and is not a suitable replacement. Portland cement is the ingredient in concrete that transforms a mixture of sand, gravel, and water into concrete. It is made by
