Introduction With the proliferation of long span bridges, steel box columns with large section size tends to applied to engineering practice widely.
In bridge engineering, the section size is relative large because the span of bridges is long and the loads on them are heavy.

Characteristics of Compressed Concrete Paving Units Produced from Washed Municipal Solid Waste Incinerator Bottom Ash Wen-Ten Kuo 1,a, Chih-Chien Liu 2,b, Her-Yung Wang 1,c and Chun-Ya Shu 1,d 1 Department of Civil Engineering, National Kaohsiung University of Applied Sciences, Kaohsiung 807, Taiwan, R.O.C. 2 Department of Civil Engineering, R.O.C.
The key factor affecting the engineering properties of WMSWIBA-based compressed concrete paving units is the cement-aggregate ratio, followed by the w/c. 3.
When the cement/aggregate ratio is 0.1 to 0.2, the compressed concrete paving units have better engineering properties in the w/c of 0.25.
When the cement-aggregate ratio is 0.3 to 0.4, the compressed concrete paving units have better engineering properties for higher w/c values. 4.
The cement content can be reduced by substituting 20% of the cement with furnace slag, but the engineering properties are not influenced.

The Countermeasures on Temperature and Shrinkage Crack of Mass Concrete Xianchun Zheng 1, a, Pengfei Li 1,b , Sizhong Sun 1,c 1 Hebei Institute of Architecture and Civil Engineering, Zhangjiakou,Hebei,075000,China azjkjyzxc@163.com, bdoomood@163.com, csun8905508@163.com Keywords:Mass concrete,Temperature crack,Shrinkage crack,Countermeasures Abstract.
Combined with practical engineering,this paper analyzes the mechanism of mass concrete temperature and shrinkage cracks, from raw material selection, structure design, construction, monitoring and management five aspects,the author respectively gives the countermeasures on temperature and shrinkage crack of mass concrete, reference for engineers.
Control the concrete into the mold temperature.In order to reduce the total mass concrete temperature rise, reduce the temperature difference between inside and outside structure, coagulation of mould temperature control measures is very important.People die temperature, closely related to the temperature of the machine, also with the number of transport, the distance, transport, construction of climate related.About the concrete into the mold temperature control, all countries have clear rules.Our country should be no more than 25 ℃, the United States ACI construction manual regulation is less than 32 ℃, Japanese architectural society reinforced concrete construction regulations in mud is not more than 35 ℃.According to the experience of the engineering practice in our country, it is recommended that the coagulation on the highest one mould temperature should be controlled below 32 ℃.
