磨细钢渣对混凝土力学性能和耐久性影响的研究
Effect of Steel Slag on the Mechanical Properties and Durability of Concrete
摘要
Abstract
The effect of different content of steel slag on the compressive strength and flexural strength of concrete was studied based on the micro aggregate and active effect of steel slag.The carburization resistance and freeze-thaw resistance of steel slag concrete were investigated by carbonization test and frost resistance test.The pore structure of steel slag concrete was investigated by X-CT.The results show that the compressive strength and flexural strength of concrete with content 10% steel slag is the highest, and the compressive strength and flexural strength of content 30% steel slag is the least.The carbonation depth of concrete with 30% steel slag has reached 12.5 mm when carbonized to 56 d.The relative dynamic elastic modulus of concrete with content 30% steel slag is reduced to 88.7% after 180 d of freeze-thaw cycles.关键词
