Introduction Non-ballasted track base plate as an important part of the non-ballasted track system, The quality of engineering directly influence the comfort, safety, durability and long service life of the high-speed railway operation.In order to improve the durability of the non-ballasted track base plate structure,and make sure its service life meet the design quirements.Combined with engineering practice, this paper comprehensive considering the index, such as slump, compressive strength, flexural strength, the electric flux etc,optimizing C40 concrete mix-designed parameters, so that ordinary high performance concrete.By using scanning electron microscopy (SEM) and SEM things such as phase analysis microscopic test method, the frantic jumble no rail base plate in acid rain and carbonization of concrete under the coupled action of microscopic structure change law and to influence on the performance of the concrete analysis in order to reveal its relationship to further improve frantic

Influence of mineralogical origin of limestone powder on the performance of complex binder material WANG Qin1,a, CHEN Jia-long1,b, ZHANG Chang-cheng2c, NIU Wei1d 1School of Civil and transportation Engineering, Beijing University of Civil Engineering and Architecture, Beijing 100044; 2China Advanced Construction Materials Group, Beijing 100190 awangqin@bucea.edu.cn, b jjj@bucea.edu.cn, czhangcc@bucea.edu.cn,dlovenewway@126.com Keywords: manufactured sand; limestone powder; water-reducing performance; mineralogical origin Abstract: The effect of mineralogical origin, elemental component, crystal structure of three types of limestone powder on the fluidity of cement-limestone paste and mortar was investigated.
Introduction The aggregate is mainly used in foundation engineering, concrete, mortar and other cement products, and its consumption is up to 90 hundred million tons per year which is 5 times of that in 2001.The value of output of aggregate amounts to 1800 hundred million (RMB 20/ton) which is the most products of exploitation and consumption of natural resource [1-4].
Therefore, much attention should be paid to the control of mineralogical origin and crystal structure of limestone powder to avoid engineering accident.

Predicting the Workability of Self-Compacting Concrete Using Artificial Neural Network Fangxian Li 1, a, Qijun Yu 1, b , Jiangxiong Wei 1, c, Jianxin Li 1 1School of Materials Science and Engineering, South China University of Technology, Guangzhou, 510640, China alifangxian@sohu.com, bconcyuq@scut.edu.cn , cjxwei@scut.edu.cn Keywords: artificial neural network; self compacting concrete; slump flow Abstract.
Many efforts have been focused on developing a reasonable test method to test and thus assess workability of concrete due to the need of application in industry and engineering[1].
However, the validity of most of these methods is based on laboratory results and no extensive verifications for corresponding test methods have been carried out by wide application in engineering practice.
In recent years, the ANNs have been extended extensively and applied to many civil engineering applications such as drying shrinkage, concrete durability, mechanical behavior and so on.
