Lightweight aggregate mainly consist of multi-crystalline structure and has many internal pores. It may be abnormal water moving in lightweight aggregate on account of the change of external circumstance. The abnormal water moving is influenced by distribution, shape, size and prewetting and each factors considerably control it. Recently, in domestic and foreign construction industry, lightweight aggregate is delivered from factory with controlling lightweight aggregate's water absorption to improve workability. But, unfortunately, there are few studies about workability and mechanical property which is influenced by controlling the percentage of water absorption. In this study, we analyzed the pore system and water absorption characteristic of domestic and foreign lightweight aggregate. And that acquired the experimental data about mechanical properties and frost resistance of lightweight aggregate concrete according to the pore system and water absorption characteristic, makes a good use of lightweight aggregate concrete. |
