Authors: Qin Ming Qiang , Zhan Wen , Xu Wen Bing , Li Jin Hui
Published: July 2014

The effect of stone powder content on the chloride diffusion coefficient and diffusion attenuation coefficient of chloride ion of mechanical sand (MS) concrete was studied. The results showed that the resistance to chloride ion permeability of MS concrete firstly increased and then decreased with the increase of the content of stone powder. The anti-permeability of the concrete which had moderate amount of stone powder was better than that of the natural river sand (NS) concrete. The diffusion attenuation coefficient of MS concrete was greater than that of the NS concrete, which was good for long-term durability of concrete structure.

Authors: Shi Yan , Yang Hua Quan , Li Xiang , Li Jia Zheng
Published: July 2014

Aging mechanism of dam concrete under the action of freeze-thaw damage was analyzed by testing macro and micro performance. The results show that compressive, splitting tensile and flexural strengths reached 58.4%, 61.3% and 57.8% of the initial values after 150 cycles. Strength is the most sensitive indicator of freeze-thaw damage, followed by weight loss rate, relative dynamic elastic modulus and ultrasonic velocity. After freeze-thaw damage, concrete structure becomes loose, porous amount gradually increased and pore size especially over 25nm expanded. Microcracks not only exist in the hydration products, but also destroy the bubbles structure in air entrained concrete, which is the main cause of freeze-thaw damage.

This paper examines the relationship between economy and development and utilization of underground space in the city center. Based on the investigations of some Chinese cities that are relatively advanced in the underground space development and utilization, this paper suggests using per capita GDP as an index to determine the development stages of the underground space. This paper also carries out a systematic analysis of the functional mechanisms of the economic factors and testifies these mechanisms with the help of case studies. The analysis and evaluation model of economic factors’ comprehensive influence is established in this paper, which proposes that the economic coefficient be used to measure the development level of the underground space in the city center. Through the calculation of the model, this paper further analyzes to what extent can the economic factors affect the development and utilization of the underground space in China’s city centers.
