The time vibrated is identical, and vibrating time is short, concrete self-compaction after vibrating.
2 comparative example performance list of table
Above-mentioned comparative example is the common normal concrete of maintenance and reinforcement, Guangxi Dadu Concrete Co., Ltd, Hunan
There is sale in the commerical ready-mixed concretes such as Bao Long developments in science and technology Co., Ltd, Shanghai Xi Yu Industrial Co., Ltd.s production company, wherein right
It is C40 concrete than embodiment 1, comparative example 2 is C50 concrete.
Can be seen that patent of the present invention by the comparison of embodiment and comparative example has compared with traditional maintenance reinforced concrete
Better timeliness, more excellent performance can effectively shorten traffic off-period for emergency maintenance reinforcing.
In conclusion epoxy resin of the present invention has, condensation is fast, intensity is high, resistant to chemical etching, wearability, durability etc. are excellent
Point, raw materials meet existing country or Industry code requirements, and raw material are easily obtained and nontoxicity；Normal temperature cure, no
Special curing is carried out, solidification temperature is at 20~70 DEG C, and early strength is higher after solidification, and solidification 4~8h intensity can reach final
80% or so of intensity is substantially shorter the time of maintenance and reinforcement close traffic；Concrete material manually vibrates and vibrates with machinery
Time is short, but concrete self-compaction, reduces caused noise problem of vibrating, and intensity is high, and deformability is good, and elasticity is restored
Rate is high, is less likely to occur to be permanently deformed under high temperature, has an excellent mechanical property, mechanical strength meet driving and requirement and
The mechanical index of normal concrete is much larger than within the same time.The present invention prepares simple, concrete material mixture mobility
Good, the presetting period under normal circumstances in 50min or so, reduces construction industries step so that construction technology is more rapidly convenient, applies
Work facilitates, cost-effective.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With.It can be applied to various suitable the field of the invention completely.It for those skilled in the art, can be easily
Realize other modification.Therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details.
