Summary:The invention relates to a formula of a special putty base mixture for aerated block masonry, and a preparation method of the special putty base mixture. The preparation method comprises the following steps: preparing a special barrel with the volume of 50L; sequentially adding 62.2-73.8wt% of putty powder, 4.8-6.5wt% of cement, 6.6-8.0wt% of gypsum powder, 1.5-2.3wt% of cast stone powder, 4.2-5.5wt% of talcum powder, 2.3-3.0wt% of diatomite, 3.4-4.0wt% of water, 0.9-1.5wt% of a flexible adhesive and 4.2-5.3wt% of a crack resistance additive to the special barrel; and stirring by using a portable electric stirring machine for 3-5min to form a uniform paste, allowing the paste to stand for 5-10min, and stirring to obtain the putty base mixture which can be instantly used. The special putty base mixture can be directly smeared on the aerated block masonry to omit a mortar plastering process and avoid material sprinkling, so the environment is healthy, and cracking and bubbling are avoided; and the special putty base mixture has the advantages of high strength, large adhesion, and no shedding in wet environment.
