Finally, by analyzing the simulation results, we give some beneficial conclusions which could provide scientific reference and important technical support for spalling prediction in the constructing process of the rock engineering deeply mined in hard brittle rock mass.
So, 《Standard for classification of engineering rock masses》gives a definition by the ratio of uniaxial compressive strength and maximum initial vertical hole axis stress () as an rule for brittle rock burst.

Prismatic specimens (100�100�200 mm) made of ECC (engineered cementitious composites) mixture, were used for the test.
One example is the recently developed ultra-ductile engineered cementitious composites (ECC) [1].
Conclusions The impact echo and pulse velocity measurements were performed to evaluate microcrack growth and degradation of elastic properties in ECC (engineered cementitious composites) materials during uniaxial compression.

How to improve the mechanical behavior of concrete is the focus problem in engineering field [1].
And among them the most ground-breaking material is the engineering cementitious composites (ECC).
The production of cement is responsible for 5% of global greenhouse gas emission created by human activities [2].Therefore, the study and development of the new type green civil engineering materials is urgently needed in China.

Summary of study on Composite Concrete Slabs Lei Wang 1, a, Hongya Zhang 1, b 1 Department of Civil Engineering Anhui University of Architecture a 174397043@qq.com, b xkb@aiai.edu.cn Keywords: Composite Structure; Composite Concrete Slabs; Prestressed Abstract.
Reinforced Concrete Slab is one of the important types of composite structure, About the concrete laminated slab of the research and the engineering application are summarized, Point out that the characteristics of Composite Concrete Slabs, the application and development of the laminated slab of recent advances at home and abroad, and look into the future of the Composite Concrete Slab’s research.
Reinforced Concrete Composite Slab is an important form of concrete composite structure, in many parts of China's engineering using laminated floor, thus strong research and development of concrete laminated slab has a great economic and social benefits.
The prefabricated sheet in the transport process is easy to crack or fracture, so the prefabricated sheet structure should be studied to improve its stiffness and strength. that laminated slab with prestressed ribbed construction speed, strong composite shear capacity, characteristic of the flexural rigidity of a larger, but laminated slabs of different structural engineering and application requires further study.
