these long-term experiments carried out with various internal\u3000factors(type of cement\uff0c type of fine aggregate\uff0c type of volcanic ash, water cement ratio)and\u3000external factors (age and exposure conditions such as in water,  in air\uff0cand in sea water)are\u3000analyzed.\u3000\u3000\u3000\u3000The long-term mortar strength test can be summarized as follows : ?tensile strength
