Preparation and Properties of High-strength Ceramsite in Low Water Absorption邓宏卫,杨英姿School of Civil Engineering,Harbin Institute of Technology摘 要:Fly ash used as the main raw materials,incorporated with sintering expansion additive and fluxing additive in different ratio,was sintered high-strength lightweight aggregates of fly ash (ceramsite......
to the abrasion resistance strength and the mass loss. Test results show that the addition of silica fume enhanced both compressive strength and abrasion resistance of concrete, and the addition of crumb rubber reduced the compressive strength but increased notably the abrasion resistance of the concrete. Silica fume concrete performed a better abrasion resistance than control concrete......
and strength. The different thermal conductivities of concrete and steel make the temperature variation more significant than that in other systems. Recently, experiments and field investigations also showed.... The high tension would cause cracking of the concrete at the point of connection for steel and concrete if the compressive stress storage of concrete bridge deck under dead load is not induced......
