Project application of the high-performance
concrete of fly ash
The summary
Every performance of this text to high-performance concrete of fly ash has done detailed research, and to the concrete respectively to person who mix of fly ash Kinds of influence of performance and fly ash concrete some questions that should notice carry on analysis and discussion in not constructing.
1. Summary
Fly ash, as a kind of industrial waste material, resources are abundant , cheap, and contain a large amount of active composition , it is modern concrete Central Africa A often important component part . The high-quality fly ash is applied to the concrete rationally , not only can replace the cement partly , save the fabrication cost of the project, And, its peculiar performance can be used in the concrete of various kinds of instructions for use very effectively, improve the performance of the concrete, It is the ideal in the high-performance concrete that admixes the material . Among it is at concrete not modern, whose name is already with cement in fly ash, collect material , water , admixture and Kind is important, become a component part in concrete. Fly ash high-performance concrete regard durability as main goal go on design mix Congeal the soil . It regards excellent durability (instead of the high strength) as the main characteristic , that is to say, concrete capital of any grade of intensity Can make into the high durability concrete . In order to reach high durability, the performance that the fly ash concrete should possess is: Mixing the state newly well Work,namely, without emanating, secreting by water, so that shaping the even , closely knit by mobility, harden not shrinking subsiding early water and Water shrink light, warm to rise low, harden course is it dwindle to do, in order to reach having the initial crack, the permeability after hardenning is low.
