Experimental Study on Performance of Reinforced Sand Aerated Concrete Materials
摘要
Abstract
On the basis of ordinary sand aerated concrete,the reinforced sand aerated concrete was prepared with gold tailing sand as silica material and basalt fiber and aerogel as reinforcing materials.The effects of basalt fiber content,basalt fiber length and aerogel content on performance of reinforced sand aerated concrete were analyzed.The results show that with the increase of basalt fiber content(0.1% ,0.2% ,0.3% ,0.4% ,mass fraction)and basalt fiber length(3,6,9,12 mm),the dry density,compressive strength,flexural strength and thermal conductivity of sand aerated concrete increase.The optimal content of basalt fiber is 0.3% and the optimal length of basalt fiber is 6 mm,at which time the compressive strength increases by 9.64% than that without fiber,the flexural strength increases by 21.42% than that without fiber,the mechanical properties are better,and the thermal conductivity is less affected.The optimal content of aerogel is 1.5% ,at which time the thermal conductivity is reduced by10.68% ,and the compressive strength and flexural strength are slightly reduced,but still meet the relevant strength requirements.关键词
