The main drawback of this material is the high level of autogenous and especially drying shrinkage that affects it, causing the deterioration of its mechanical properties.
The type and dosage of the activator as well as the method of curing have a significant effect on the course of the hydration process and final mechanical properties [2].
The main motivation for the research is to reduce the cracking tendency and improve the tensile properties of these materials.
Since spontaneous drying of the material affects its final properties, conditions which are supposed to have minor or no impact on the mechanical properties of AAS mortar were chosen.

To master the regular pattern of the influence of relative factors on physical and mechanical properties of phyllite is the basis to establish an effective construction method.
As a regional metamorphic rock, the engineering properties of the phyllite are rather complex.
To master the regular pattern of the influence of relative factors on physical and mechanical properties of phyllite is the basis to establish an effective construction method.The influence of water and mineral composition on physical and mechanical properties of phyllite was analyzed through relevant tests.
It is necessary to find out a set of well-established scientific construction methods for phyllite tunnels, and one of the bases to find an effective construction method is to acquire the law on the influence of relevant factors on physical and mechanical properties of phyllite.
Test on influence of mineral composition on physical and mechanical properties of phyllite A large number of tests have been done during the construction process, according to the tests, the results of the physical and mechanical properties of phyllite that is mixed with different minerals are shown as Table 4.
