Component in 1-3 has increased SILICA FUME newly, and the compression strength of the compressive strength rate embodiment 1-3 of embodiment 4-7 has to a certain extent
Raising, thus, by be added SILICA FUME, the compression strength of pervious concrete aerated bricks can be improved to a certain extent.
It can be obtained according to the data comparison of the embodiment 1-3 and embodiment 4-7 in table 1, the component ratio in embodiment 4-7 is implemented
Component in example 1-3 has increased bamboo fibre newly, and coefficient of permeability of the coefficient of permeability than embodiment 1-3 of embodiment 4-7 has to a certain degree
On raising, thus, by be added bamboo fibre, the water penetration of pervious concrete aerated bricks can be improved to a certain extent
Can, so that the permeable better effect of pervious concrete aerated bricks.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
