The scale of the construction garbage is gradually increasing with the booming domestic construction industry. The rate of resource utilizing is less than 1% as most of the construction garbage disposed through stacking or landfills.To avoid the waste of resources, a routine method is applied as the garbage crushed into recycle aggregate before utilizing. However, in the process of crushing, it will inevitably generate regenerating powder of which the particle size was lower than 0.075nm. It would bring a second pollution if an inappropriate disposition was conducted. As a result, In this test, to survey the activity of calcium carbonate aggregate mixed with concrete, an acid leaching method was employed while the active components of mixtures were analyzed with XRD technology. In addition, heating after mixing with discarded brick powder was carried out while its effect was compared with that of normal concrete.Therefore, the focus of this test is to characterize the activity of calcium carbonate aggregate mixed with concrete and establish a modification method, as well as a comparative analysis of mixture modified before and after.
顺便问一句,你这个是硕士还是本科的摘要? |
