锰渣对混凝土力学性能和耐久性的影响
Effect of Manganese Slag on the Mechanical Properties and Durability of Concrete
摘要
Abstract
The effect of different content of manganese slag on compressive strength and flexural strength of concrete was studied by using basic mechanical method.The carbonization resistance and frost resistance of concrete with manganese slag were investigated by accelerated carbonization test and frost resistance test.The pore structure of concrete with manganese slag was investigated by mercury intrusion porosimetry.The results show that the compressive strength and flexural strength of concrete decreased with the increase of manganese slag content when the content of manganese slag was more than 10％;The carbonization resistance and frost resistance of concrete with 30％manganese slag were the worst,for example the carbonization depth has reached 10.0 mm after accelerated carbonization for 56 d and the relative dynamic elastic modulus decreased to 0.71 after freeze-thaw 240 cycles;The porosity was decreased and the pore size was refined after carbonization;Freeze-thaw cycles lead to the increase of porosity and pore size.关键词
