Influence of fly ash as cement replacement on chloride penetration and frost resistance of recycled concrete Xianghao Wu 1,a ,Pan Yuan1,b and Yantao Jiao 1,c 1College of Ocean Environment and Engineering, Shanghai Maritime University, 1550 Pudong Avenue, Shanghai, 200135, China aXhwu@shmtu.edu.cn, bZhuiyu4951@163.com, cJiaoyantao2000@yahoo.cn Key words: fly ash, recycled concrete, pore structure; chloride penetration, freeze-thawing cycle Abstract.
It will be widely used in areas such as civil, hydraulic and ocean engineering.
That's useful for the extend application of recycled concrete in marine engineering.
Free chloride ion concentration of each part powder sample is measured by the method of titrating water-soluble chloride ions in accordance with “code for concrete test of port and waterway engineering”(JTJ270-98).
In this study, rapid freeze-thawing test on the basis of “code for concrete test of port and waterway engineering”(JTJ270-98) is adopted.

Study on Load-Bearing Characteristics of Double Layer Stirrup Confined Concrete Square Columns Linzhu Sun 1, a, Fang Yang2, b, Yagang Zhou3,c, ziling Xie4, d 1, 2, 3, 4School of Architecture and Civil Engineering, Wenzhou University, Zhejiang, China alinzhusun@163.com, byf3077@126.com, czhouyg@wzu.edu.cn, dxiezl@wzu.edu.cn Keywords: square column; confined concrete; double layer stirrup; bearing capacity Abstract.
Engineering experience showed that: when the stirrup characteristic value of a concrete column is small, the single layer stirrup has insignificant lateral constraint effect in the concrete column, while the double layer stirrup, substituting for the single layer stirrup, will effectively improve the strength and ductility of the concrete column.

The Combined Solar with a Dual Heat Source Heat Pump Applied in a Greenhouse Heating System——an Operation Optimization of Water Source Heat Pump Xianpeng Sun 1a, Zhirong Zou 1b, Yue Zhang 2c 1 College of mechanical and electronic engineering of North West Agriculture and Forestry University, Yang Ling in Shaan Xi, 712100, China 2 Key Laboratory of Thermo-Fluid Science and Engineering, Ministry of Education, Xi'an Jiaotong University, Xi’an in Shaan Xi, 710049, China aSunxianpeng@nwsuaf.edu.cn,bZouzhirong2005@163.com,czhangyue@mail.xjtu.edu.cn, Key words: Finite-time Thermodynamics, Greenhouse Heating System, Water Source Heat Pump, COP Abstract: Based on the finite-time thermodynamic theory, an operation optimization, of water source heat pump in the combined solar with a dual heat source heat pump which is applied in a greenhouse heating system, is made.
The data of outdoor temperature Ta can be the measured data or meteorological data of typical years and we can also use first order harmonic to simulate the change of ambient temperature in engineering: a period of change of ambient temperature is 24 hours and the lowest temperature Tmin appears at 3 o’clock in the morning while the highest temperature Tmax appears at 15 o’clock in the afternoon.
The greenhouse is different from general civil buildings.
