Description
Technical field
The present invention relates to technical field of buildings more particularly to a kind of cement base porous pavement material specific complex admixture and
It is applied.
Background technology
Porous pavement material can be divided into two major class of slug type and baking-free type by production technology.Though slug type porous pavement material
Right intensity is high, wearability is good, but production technology is complicated, needs high-temperature calcination, and resources and energy consumption is big, and price is high.Baking-free type
Porous pavement material is divided into as two kinds of fundamental types of resin mating-type and cement mating type, resin base porous pavement material generally with
The organic polymers such as epoxy resin are cementing agent, and such porous pavement material has the spies such as intensity is big, good toughness, wear-resisting property are good
Point, still, since using organic polymer as binding agent, production cost is high, loss of properties on aging；Cement base porous pavement material
Material can largely use industrial solid castoff etc. excellent since the cost of raw material is low, simple production process, endurance quality are good
Gesture so that cement base porous pavement material becomes the hot spot of research, while has a vast market prospect.
But striaght cement shrinking percentage in hydration process is big, under the effect of contraction that gathers materials, hardened cement paste and aggregate Interface
Between generate larger stress difference, be also easy to produce micro-crack, the cohesive force between reducing slurry and gathering materials causes the permeable road of cement base
The compression strength retraction of plane materiel material later stage, and wear no resistance, the popularization of cement base porous pavement material is limited to a certain extent
Using.
In the prior art, the resource utilization rate for discarding slag is relatively low, and big steel slag is accumulated for a long time, does not only take up a large amount of soil
Ground resource, and also create the pollution of environment and the waste of resource.Have in the prior art and add steel-making slag powder as admixture
Enter to the report in cement base porous pavement material, the expansion of f-CaO and f-MgO contained in steel-making slag powder can compensate pure water
The self-constriction that muddy waterization generates, while iron content height can improve the wearability and shock resistance of ground surface material in slag, still
Singly mixing can cause the early strength of ground surface material low or even crack；Slag powders activity is higher, but singly mixes and be also easy to produce excreting water phenomenon,
Self-constriction simultaneously is larger；Though flyash has good micro aggregate effect, particle shape effect, volcano ash effect, it is as blending
Material is added in cement base porous pavement material, be there are problems that cement base porous pavement material impact resistance and is worn no resistance,
Early strength is relatively low simultaneously.The above problem directly result in cement base porous pavement material endurance quality it is poor the problem of.
