If we have a look at the sulphate resistance performances of the portland

cement(PC) and calcium aluminate cement(CAC), after 30 days of sulphate

exposure the shrinkage behaviours start to differentiate.

CAC has high acid resistance until 2 pH value.

Unlike Portland cement, CAC does not release lime during hydration. This

property gives good chemical resistance to acid corrosion and to a large

number of aggressive environments.

CAC do not release Calcium Hydroxide as a hydration product when used in

a formulation. Therefore, it shows high resistance in acidic environment.

Some of the usage areas are;

acidic or basic process pools,

livestock floors,

fertilizer plants floors,

hospital and school laboratories,

petroleum and geothermal wells

Here are the critical considerations while using CAC as a binder in floor tiles;

Hot curing process should never be done.

The equipment used must be clean and potable water used.

Water / Ratio must be at most 0.4.

Sand and aggregate gradation should be compatible with cement.

The minimum amount of water should be used.

Here are the critical considerations while using CAC as a binder in floor tiles;

It may give different reactions than Portland Cement with different type of

additives. It should be used after having trials in the laboratory.

Materials that are placed in the recipe should not be left in direct sunlight. To

avoid temperature increase in the mix, it is advised to use ingredients with

ambient temperature.

For higher temperatures such as 1000 °C or more, calcium aluminate clinker, or

fireclay must be used as an aggregate in the recipe.
