Cement Substitution in High-Temperature Concrete
An alternative binder to calcium aluminate cement (CAC) was prepared by the sol-gel method. Chemically pure systems such as tetraethylorthosilicate (SiC<sub>8</sub>H<sub>20</sub>O<sub>4</sub>) and nonahydrate of alumina nitrate (Al(NO<sub>3</sub>)<s...
