An Improved Test Method for the Detection on Alkali-Silica Reactivity of Aggregate Jing Wang1, a, Guhua Li1, Junpeng Zhang2 , Junjie Zhou1, Fengming Sun1, Xianxiao Peng1 1School of Civil Engineering, Southwest Jiaotong University, Chengdu, Sichuan, 610031, China 2China Railway Fifth Survey and Design Institute Group Co., Ltd, Beijing, 102600, China awjtl01@163.com Keywords: alkali-silica reaction (ASR); mortar-bar method; accelerated mortar-bar method; improved test method Abstract.
The authors based on accelerated mortar-bar method to put forward an improved test method to evaluate the alkali-silica reactivity of slate aggregate, the water bath with temperature control maintaining 80.0 ± 2.0 °C, it takes steam curing to ensure there is no external alkali into the interior, Compared with the accelerated mortar bar method, it’s a new test method which closes to the actual engineering conditions.
It means that to achieve to 0.46% of accelerated mortar-bar method will be a very long time; it does not accord with the need of actual engineering now.
Improved test method conditions are similar to the vast majority of actual engineering environment conditions.

., has received considerable attention in the academic circle and engineering, and has been studied and applied extensively and increasingly [1-4].
Given that most of domestic FRP strengthening researches are aimed at under-reinforced concrete joist in practical engineering, especially in the bridge engineering, the ratio of reinforcement is higher and its cross-section is larger.

The Uncertainty Analysis of Health Management Strategies for Aero-engines Zhenhua Wen a, Xin Yinb, Yuanpeng Liuc School of Mechatronics Engineering, Zhengzhou Institute of Aeronautical Industry Management, Zhengzhou, Henan Province 450015 ,P.R.
But because the hypothesis condition is an ideal state and is more or less different with practical engineering condition, the maintenance decision-making based on which gets a certain degree of uncertainty and limit the actual popularization and application of maintenance decision-making methods.
Plus, there is a certain limit for the generalization capacity of the model itself, so as for specific engineering conditions, the uncertainty of output decision-making for different models always exists and the only difference is the degree of uncertainty.
