Hydrophobic Cement. This type of cement includes admixtures, which reduces the wetting capability of cement grains. The typical hydrophobic admixtures are acidol naphthene soap, oxidized petrolatum, etc. when hydrophobic cement is used, the fire pores in concrete are uniformly dispersed, and so the frost resistance, as well as the waterresistance of this concrete, are substantially increased.
