Superhydrophobic Calcium Aluminate Cement with Super
In the present study a simple and cost-effective method for the preparation of a superhydrophobic calcium aluminate cement (SCAC) with superstable mechanical stability is reported. Room-temperature vulcanized silicone rubber (RTV) is used as an internal hydrophobic additive in concrete. The as-prepared cement surface and all cross-sections exhibit superhydrophobicity.

Recent advances in refractories — aluminate binders and
cement. Calcium aluminate cement (CAC) and a method for its industrial production were patented by Lafarge in 1908 (Soc. J A. Pavin de Lafarge 1908). The first industrial production of calcium aluminate cement was by Lafarge in 1913. It was not until the 1920s that the heat resistant properties of calcium aluminates were exploited (Arnould 1922).

High Alumina CementManufacturing Pros Cons
High Alumina Cement (HAC) is also known as calcium aluminate cement (CAC) or aluminous cement is composed of calcium aluminates. High alumina cement was first manufactured by Lafarge the cement producer and became available in the UK in 1925. It has good resistance to be resistant to the chemical attack which is required in marine construction work.

Calcium aluminate cement concretes are not rapid setting. They are however rapid hardening that is they will develop as much strength in 24 hours as Portland cement concrete will achieve in 28 days. Calcium aluminate cement concretes should be cured for at least 24 hours using a water spray or fog ponding wet burlap or a curing membrane.
