This cement is very much resistant to sea water attack .
Its comprssive strength is nearly double of that of ordinary cement /
Thereis no trace of free lime and hence this cement is more sound than ordinary cement .
There is no trace of free lime and hence this cement is more sound than ordinary cement .
It is highly resistant to sulphate bearing waters and sea waters and is used for constructions near sea shore and also under water .
It is also used for making refractory and heat resistant concrete .
It is used for sealing rocks or concreteing against internal water flow .
It is not used for mass concrete works as it generates rapid heat of hyration .
This cement is called cement Fondu in France , "lighting " in England and "lumnite" in united states . While using , this cement must not be mixed with any other types of cement as heat evolved during setting is greater than any other cement .
