calcium aluminate cement (CAC) with/out phosphate modiﬁion by a heat-treatment during the solidiﬁion. The reduction of water in the CAC was found restricted by the rapid formation of crystalline hydration phases, whereas the phosphate-modiﬁed system
High alumina cement (formerly known as alumina cement). It is based on calcium aluminate and clinker with an alumina content of about 50% as raw material. A hydraulic cementitious material with aluminate as the main mineral component is prepared by calcining and grinding in a certain proportion.
A potential alternative is an acid–base cementing system, based on mixing calcium aluminate cement (CAC) with acidic phosphate solutions. Although these systems have been studied previously, there has been no systematic investigation to identify phosphates for producing suitable matrixes for appliion in radioactive waste encapsulation.

CEM cement produces an alkaline pH and releases calcium in a similar manner to white ProRoot MTA (Asgary et al. 2008c; Amini Ghazvini et al. 2009). In addition, CEM cement releases significantly higher levels of phosphate compared to PC and white ProRoot MTA during the first hour after mixing (Amini Ghazvini et al . 2009).
