Stress-Chemistry Mechanism of Mortars Made with Steel Slag Sand Yunxia Lun1 ,a, Shaoshun Liu 2,b, Mingkai Zhou 3,c,Xiaofan Liu1,d 1 School of civil engineering, Wuhan polytechnic university, China 2 Management department of guixing expressway, China gezhouba group Company, Limited, China 3School of material science and engineering, Wuhan university of technology, China alunyunxia@163.com, bliushaoshun2008@163.com, czhoumingkai@163.com, dhnsfine@163.com Keywords: Stress Concentration; Volume Instability; Expansion Component; Enrichment; Uneven Distribution Abstract: A stress-chemistry method was used to investigate the expansion behavior of mortars made with steel slag sand(SSM).
Every year nearly 50 million tons of steel slag is generated, but the utilization rate is only 10% in civil engineering in China [1].
However, the excellent physical and mechanical properties of BOF slag has been reported as a promise materials for potential use in civil engineering as aggregates [6-9].

Analysis on the Mechanical Properties of Connections on Cold-Formed Square Steel Column and Beam Yong Yaoa , Yun-peng Chub School of Civil Engineering and Architecture, Southwest University of Science and Technology, Mian yang, Sichuan 621010; China ayy001221@163.com , bchuyunpeng@swust.edu.cn Keyword: Cold-Formed Square Steel Tubular; Welded Beam-Column Joint; Bearing Capacity; Ductility; Stiffness Abstract.
Because axial compression ratio had great influence on mechanical properties of node, under different axial compression ratio, the bearing capacity, stiffness etc of two types nodes were analyzed and discussed by finite element method to provide reference for the engineering application.

DIRECT TENSILE STRENGTH OF LIGHTWEIGHT CONCRETE USING POLYPROPYLENE COARSE AGGREGATE COATED WITH SAND Purnomo Heru1,a*, Yuandry Rizki Andhika1,b, Tjahjono Elly1,c 1Civil Engineering Department, Universitas Indonesia, Depok 16424, Indonesia aherupur@eng.ui.ac.id, bandhika.yuandri141@gmail.com, celly@eng.ui.ac.id Keywords: Plastic coarse aggregate, Direct tensile strength, Polypropylene, Sand coating, Cylinder specimen Abstract.
Since the direct tensile strength is lower than the other two experimental method results, its value can be considered as conservative for the design and construction of civil engineering structures.
The authors also conveyed their gratitude to the staffs of the Laboratory of Structure and Materials, Department of Civil Engineering, Faculty of Engineering, Universitas Indonesia for their support in the experimentation program.
