Every text ( and old Biblical epic movie) reports that the pyramids were made of limestone blocks positioned by thousands of slaves but Joseph Davidovits (a French Cemical Engineer) proposed, in the 1980's that at least some of these blocks were made of concrete. The lower tiers were done by the sweating slaves method, but the higher layers were made by workers carrying bags of wet cement to moulds.
MIT is actually reviewing this proposal by duplicating the theorozed Egyptian cement mixture.
The outer stone layer of the pyramid of Khufu was built with Tura stones. This is a l white limestone. Tura limestone is quite soft and can be worked easily but, after being exposed to air, it hardens.
