The mortar admixture has a shorter storage period without preservatives. In order to prolong the storage period of the mortar admixture and the performance of the product is not affected, the anticorrosion research experiment of the mortar admixture product is carried out. Through this test, it can be seen that the higher the temperature of microorganisms under the condition of incomplete sealing outdoors, the faster the mildew cycle. Then by adding isothiazole preservatives to improve the mildew cycle and appearance changes of admixtures, by testing the number of colonies in the samples after adding preservatives and testing the performance of mortars, when the preservative content is 2.0‰, the inhibition bacteria effect is obvious. The experimental results show that the addition of preservatives can effectively inhibit the growth and reproduction of bacteria, significantly prolong the mildew cycle of mortar admixtures, and have no effect on the performance of mortar admixtures.
