Thiazole, so that concrete thermal stability with higher and chemical stability, when so that concrete being exposed to the sun, concrete is not easy
Cracking, preferable reinforcing concrete so that the impact resistance of concrete and compression strength are promoted, at the same make concrete have compared with
Good anti-ultraviolet property, extends the service life of concrete.
The data of comparative examples 4 and embodiment 8, it is seen that 2- (2H)-benzotriazole -2- base) -6- dodecyl -4-
Methylphenol, so that the impact resistance and compression strength of the sample of concrete preparation are promoted, so that the road prepared by the concrete
The structural strengths such as face are higher.
The data of comparative examples 5 and embodiment 8, it is seen that tufa stone is added in concrete, is conducive to preferable reinforcement
Concrete improves the compression strength and anti-permeability performance of concrete, extends the service life of concrete.
The data of comparative examples 6 and embodiment 8, it is seen that attapulgite is added, so that the effect of concrete reinforcement is preferable,
So that concrete has preferable compression strength and impact resistance, extend the service life of concrete.
The data of comparative examples 7 and embodiment 8, it is seen that durian powder is added in concrete, is conducive to by concrete
Middle addition durian powder, preferable reinforcing concrete, the preferable intensity for improving concrete so that the impervious effect of concrete compared with
It is good.
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
