Application of Fly Ash-based Geopolymer for Structural Member and Repair Materials YODSUDJAI Wanchai Department of Civil Engineering, Faculty of Engineering, Kasetsart University, 50 Ngamwongwan Road, Chatujak, Bangkok, 10900, Thailand fengwcy@ku.ac.th Keywords: Fly Ash-based Geopolymer, Repair Materials, Reinforced Concrete Beam, Flexural Behavior, Rebar Corrosion Abstract.
These properties afford geopolymer great applications in many fields and industries such as civil engineering, automotive and aerospace industries, non-ferrous foundries and metallurgy, plastics industries, waste management, art and decoration, and retrofit of buildings.
To use the geopolymer mortar as the repair material, it is necessary to study the engineering properties of geopolymer mortar; such as, strength and durability properties which are the important properties for the repair materials.
Therefore, the testing the engineering properties under Thailand’s climatic condition is highly important in order to develop the geopolymer mortar for using as the repair materials.

Synthetic Snow Substitutes as the Basis for the Recreation and Sports Facilities Sustainable Operation Marina Afonina1,a*, Sergey Ivanov1,b 1Moscow State (National Research) University of Civil Engineering, Yaroslavskoye highway, 26, 1129337, Moscow, Russia amarinamgsu@yandex.ru, b24sport@mail.ru Keywords: ski resorts, snow substitutes, year-round operation, recreation and sports facilities, Snow Plast 365.
The fundamental properties of snow and ice, the main winter objects’ attribute, are studied by engineering glaciology, therefore, already developed knowledge in this area is used in the design of complexes for winter sports.
Such an engineering solution provides the coating, the best adhesion of skis and snowboards to the surface, approaching the sliding parameters on natural snow cover.
