The concrete mixes marked as R3, R4, R5, and R6 contain aggregate grains of size ranges 0–4 mm, 0–8 mm, 0–16 mm, and 0–22 mm, respectively.
In this case, because of data evaluation limitations (AE scanning with insufficient number of sensors), only the AE data were recorded; however, provided with more advanced instrumentation and evaluation [5].

Third, wrote down the exact number of the volume, and the tapped density was the ratio of its mass to its volume.
However, when the concentration is too high, it will product more nuclei, and the nucleation rate is faster than its growth rate, and inhibit the growth of the nuclei, thus it leads to smaller grain size, more defective lattice, much disordered accumulation, and more amorphous components.

Experimental procedure
2.1 Raw materials
Al2O3 /epoxy resin composite samples were prepared, with E44 epoxy resin as the matrix materials, different particle size of α-Al2O3 as filler, ethylenediamine as curing agent.
2.2 Test methods
Preheated the epoxy resin in oven at 85℃ for 30min firstly, then added Al2O3 ceramic grains into it and mixed well.

A large number of MD simulation studies of shear deformation have been reported.
Heino et al. studied mechanical properties and dislocation initiation in copper under shear deformation using MD simulations; they even introduced a grain boundary and an initial cut to model samples with defects [1, 2].

However, due to the limit of forming conditions, the number of synthetic materials is few.
With an increase of BaTiO3 content, the interaction and continuity of BaTiO3 grains are enhanced and then the polarization of composite become easily.

There are several reasons ,firstly, grain size of Metakaolin almost between 1~2μm ,therefore, it’s have eminent filled function, the filled function benefit to mend the porosity and improve the pore structure and then promote strength development and reduce the shrinkage; Secondly, Metakaolin contains a lot of activated silicas and activated aluminas, when added to cement-based materials them could react with Ca(OH)2 and some hydration products rapidly and produce a mass of C-S-H gels and spiculate ettringites which could lead to a little expansion and strength increase, however, because of the activated alumina could react with the ettringite and consum eettringite step by step, that’s probably lead to the expansion fade away.
