Advantages and Disadvantages of Tu-zhang-fang on Building Materials Advantages.
Building materials are obtained from local sources, and the building is in concordance with the environment, and having ecosystem rationality.
At last, Tu-zhang-fang needs few building materials, which mainly can be obtained from local sources.
Experimental use of soil materials should come from more than two Tu-zhang-fang in different areas of Yi minority’s settlements.

Alkali-activated materials are an alternative to conventional Portland cement in the production of concrete.
Introduction Alkali-activated materials are an alternative class of inorganic binders.
The advantage of alkaline activated materials over cements is that they are much more environmentally friendly.
In addition to the fact that there is no carbon dioxide production during alkaline activation, another significant benefit is the fact that large-scale industrial waste materials such as blast furnace slag or power ash can be used as the main materials.

The choice of similar materials and the design of mix proportions is a key step in landslide model test.
On the basis of experiment, we conduct a research for the similar materials which may sufficing volume weight, cohesive force, angle of internal friction, deformation modulus, and the infiltration coefficient on the same time.
Based on the predecessors' experience ,this paper conducts an exploration research on the new mix proportion of similar materials which satisfy the similarity of the deformation, destruction, and infiltration ( i.e, volume weight, deformation modulus, cohesive force, angle of internal friction and infiltration coefficient are all similar) to meet the practical landslide model test requirements. 2 Choices of Similar Materials and Schemes of Mix Proportion The landslide model test is based on the similarity between model and prototype.
According to the principles above and the overall requirements of the landslide similar materials, which is a kind of high volume weight, low cohesive force, low deformation modulus, low infiltration coefficient and the right angle of internal friction granular materials, I successively explores two sets of similar material test plan. 3 The First Set of Similar Material Test Plan The first kind of similar material is the mix of high-strength glass micro beads and talcum powder. 3.1 Physical Properties of the Similar Material High-strength glass micro beads are the primary counterweight material.

The advantages of composite materials, on the one hand, can enhance the protection of iron oxide and reduce the loss of iron, on the other hand, can give full play to the synergistic effect between different materials.
In the selection of carrier materials, besides the stability of materials and the compatibility with iron, the cost factor is also very important.
Due to these materials are generally charged negatively and have large specific surface area, iron ions are easy to accumulate on the surface of clay materials or enter their internal space through ion exchange.
