Authors: Dong Rong Zhen , Wei Jun , Qi Yun Xuan , Guo Liang Ting , Chen Bing , Liu You , Wei Ran
Published: January 2014

The compensation effect of expansive agent on shrinkage of self-compacting concrete (SCC) are studied. The deformation of Concrete was tested by concrete comparator, and the qualitative and quantitative analysis of hydration products were done by X-ray diffractometer (XRD). The results show that the dosages of mineral admixture and curing conditions affect the application results of expansive agents markedly. SCC samples containing expansive agent cured in the water are expanding within the test time. In the case of watering condition and natural curing condition, the samples are always shrinkage within test time, but mineral admixtures have a good effect to resist the shrinkage of SCC. Microstructure analysis show that ettringite content is reduced slightly due to the reduction of the alkalinity of SCC resulted by more mineral admixture. However, when at water curing condition, humidity inside SCC is much higher, which makes ettringite content larger even though with more mineral admixture. So, curing is the most important factors for the micro-expansion of SCC containing expansive agent.

The most proportion of mineral impurities in this coal sample is Kaolin, which is very argilliferous and harmful for fine coal flotation. In this paper, the authors use recleaning process and add depressant inslurryto reduce the concentrate ash. The results show that the most appropriate depressant is sodium haxametaphosphate and the best flotation conditions are 80g/L feed concentration, 0.80l/t Kerosene dosage, 0.06l/t 2-octyl alcohol dosage, approximately 800g/t sodium haxametaphosphate dosage, and 4 minutes depressant action time. Consequently, the concentrate ash content decreases 5% than batch-floatation test.

The influence of grain refiner on the microstructure and mechanical properties of pure aluminum was investigated by separate and combined addition trace ScZr elements. The results show that the grain refinement effect of 0.2%Zr added alone is better than that of 0.2%Sc, each of them separate addition can make the strength and hardness of alloys increased obviously, and the decrease of the ductility is not remarkable, but the hardness increase of the alloy with 0.2%Sc is more significant than 0.2%Zr because of the strongly solid solution strengthening of Sc. While, the combined addition of 0.2%Sc and 0.2%Zr possesses the most excellent grain refining effect and change the growth morphology from columnar grains to equiaxed ones, the average grain size of the alloy is dropped to only about 100μm, and the strength, plastic and hardness of the alloy meet the reasonable matching, which is largely attributed to the effectively reduce of the Al-Sc eutectic point and the formation of Al3(Sc, Zr) composite particles, These Al3(Sc, Zr) particles can not only keep all the beneficial effect of A13Sc but can act as extremely effective nucleation sites of α (Al) and cause strongly fine-grain strengthening effect.

Based on the Kalman filter, A multi-frequency eddy current signal demodulation method is proposed. By directly sampling the analog signal of multi-frequency eddy system, the multi-frequency phase and amplitude information of eddy current will be obtained by the proposed method immediately and synchronously. Contrasting the traditional method, the proposed method does not need hardware demodulation circuits and the circuit structures are also simple. Moreover, the proposed method is more flexible, which may be configured to any frequencies parameters by software way and no longer dependent on specific hardware circuits.

Beam-column joints can play a key role on the seismic behavior of reinforced concrete buildings. Until now studies and experimental investigations on this topic have been mainly focused on beam-column joints with stiff beams, i.e. beams with height larger than the thickness of the adjacent floor slab. However, especially in the European residential building stock, frame structures are often equipped with wide - therefore rather flexible - beams. However, not many studies have been devoted so far to this type of connection, therefore an experimental investigation on full scale beam-column joints with wide beam was planned at the University of Basilicata and is currently in progress. In the present paper the main results of two cyclic tests are reported and discussed specifically analyzing the role of the axial load applied to the column on the joint performances and damage mechanisms. Test results highlights that the axial load value has a significant influence of on deformation capacity and ductility behavior.

Ecological and environmental governance is vital to global sustainability. The role of energy saving in achieving CO2 emissions reductions is known to be important for environment protection . PPPs governance in DEG can be considered key to driving down traditional energy demand and hence CO2 emissions in the coming sustainable economy. Over the coming decade, Centralized Energy Generation (CEG) will decline relative to Distributed Energy Generation (DEG) such as solarphotovolatic, microturbines, fuel cells, combined heat and power and variety of renewable energy. This shift promises to improve power reliability, deliver cleaner power and avoid significant investments in transmission infrastructure. As an integrated hybrid governance system of sustainability, PPPs enjoys high efficiency of governance via collective efforts of multi-agents involved. In order to promote the governance quality of DEG, it is of importance to harness the advantages of integration of PPPs Governance in DEG project. This paper examined PPPs governance in order to improve efficiency of Distributed Energy Generation, it firstly briefly outlines the profile of PPPs, then illustrates the essentials of good PPPs governance in global DEG governance context. Finally, it draws the conclusion that how to ensure the efficiency of PPPs in collective governance of DEG projects.
