| Abstract: | The effect of fly ash and silicon fume on the sulfate resistance and inner pore distribution of lightweight aggregate concrete is investigated.Test results indicate that, compared with normal concrete,the sulfate resistance of lightweight aggregate concrete is better,admixed mineral admixtures can increase the sulfate resistance and optimize the inner pore distribution of lightweight aggregate concrete remarkably.The mechanism of high strength lightweight aggregate concrete to resist the attack of sulfate liquor is discussed in the paper. |

| Keywords: | high strength lightweight aggregate concrete lightweight aggregate pore distribution sulfate resistance |
