Mineral transition mechanism of calcium aluminate with

Abstract The mineral compositions of CaO-Al2O3 clinker sintered at 1500 °C for 2.0 h are CaAl2O4 and Ca12Al14O33 when the molar ratio of CaO to Al2O3 is 1.2, which is composed of irregular particle with clear boundaries. Increasing lime dosage promotes CaAl2O4 and Ca12Al14O33 react with CaO to form Ca3Al2O6, and also decreases the crystal stability of CaAl2O4 and Ca12Al14O33.

Introduction. Hibonite (CaAl12019) and calcium dialuminate (Cd1407) are among the most refractory minerals observed in calcium-, aluminum-rich inclusions (CAIs) in chondritic meteorites. Hibonite was discovered in the Leoville and Allende carbonaceous chondrites [I]. It is found in CAIs in carbonaceous, ordinary, and enstatite chondrites [2-41 and is fairly common in CAIs in CM2 chondrites

AMORPHOUS CALCIUM ALUMINATE

Amorphous calcium aluminate dissolves most rapidly releasing aluminate ions into the pore structure giving, in coination with calcium sulphate, extreme fast formation of calcium tri-sulpho-aluminate; 3CaO,Al2O3.3CaSO4.32H2O. It is found that formation of crystalline C4A3Ŝ is practically instant and all sulphate consumed.

Calcium Aluminate - an overview | ScienceDirect Topics

Calcium aluminate cements (CACs) represent an interesting alternative because their pore water pH, ranging from 11.4 to 12.5, is reduced as compared to OPC (Goñi et al., 1991). The main difference between Portland and calcium aluminate cements lies in the nature of the active phase that leads to setting and hardening.
