Application Study On The Flyash In Lime Flyash-loess Foundation

The fly ash is the wasted ash that the boiler combusted coal in the fire power station. Because of the development of the Society and economy, urged the development of the power industry, the fly ash of exhaust is increasing year by year, causing many economic and social problems. How in great quantities and efficiently of the exploitation fly ash have become the outstanding problems of present stage. The exploitation history of the fly ash is very long, the realm is extensive, but uses the ash quantity not greatly. For raising the utilization, emphasized to study it on foundation handle of application in the paper. The lime-loess foundation is the method that a kind of processing is the simple, economic and valid collapsible lime-loess foundation to counteract, having already got the extensive application in the engineering. Currently the applied fly ash-loess foundation contain lime (lime and loess) foundation and lime-fly-ash loess (lime, the fly ash and loess) foundation, but the fly ash-loess matching ratio and materials match the aspect of the theories research to still get behind with the engineering fulfillment far and far, so gathers to anticipate to matching ratio with to compare the choice and the applied mathematics method assurance fly ash compositions to make the further study on the fly ash-loess foundation. At first, introduced urgency of the exaltation fly ash utilization and the physics and the chemistry property of the fly ash, further inquiring into fly ash in the fly ash-loess foundation of hardening mechanism in the paper. Through the room experiment, study on the strength of the fly ash-loess and its affects the factor. The suggestion usage was put on one fly ash-loess matching ratio is1:9(fly ash and loess) in the paper. This is a match that synthesizes the consideration from the mechanics and the fly ash of utilization to compare. The next, the time factor from two fly ash-loess make sure its best matching ratio for: 1:2:7(lime, the fly ash and loess) in the sheared experiment. Finally, the mathematics model within applied gray system theories carried on analyses fly ash-loess strength factor.
