Description
Technical field
The present invention relates to a kind of strong concrete and preparation method thereof.
Background technology
Along with economic fast development, the building industry of China is also in fast development, and the usage amount of concrete is also greatly increased,
But concrete is in pouring hardening process, owing to the reasons such as chemical shrinkage, shrinkage and drying shrinkage can cause volume contraction；And it is single
Position cement consumption and water consumption are the most, and volume of concrete is the biggest, and moisture evaporation is the fastest, then shrink the most obvious；Generally, often
1m3 concrete shrinkage value is 0.04～0.09%, causes concrete to produce cracking, seepage, steel bar corrosion, loss of prestress etc.
Adverse consequences.
In order to solve this problem, for different concrete mixs, conservation system and restrained condition, mix appropriate
Extender or waterproofing agent can solve the adverse consequencess such as the cracking of concrete, seepage, steel bar corrosion, loss of prestress, and make place
Concrete density under restrained condition improves, improve that it is impervious, therefore a lot of engineer applied extender or waterproofing agent.
" impact on concrete impermeability of the CTF Concrete synergist " (Li Qingchuan, Chen Hongtao, Chen Xiangrong, Liang Jinghuai,
Huang Chongyi, Chinese periodical " commerical ready-mixed concrete " the 03rd phase in the 2011st) CTF Concrete synergist to concrete permeability resistance
Can test results and analysis in refer to: penetrate into CTF Concrete synergist when not changing match ratio consumption, concrete
The slump all has substantially increasing, and collapsing property of guarantor is good, and workability is good, even if also can keep the work of concrete when reducing by 15% cement consumption
Make performance, even make moderate progress；Mix CTF Concrete synergist when not changing match ratio consumption, the seepage-resistant grade of concrete and
Comprcssive strength all has and promotes by a relatively large margin, can improve more than one grade of concrete strength, and compact structure, and internal void is with super
The most in the majority, it is distributed stable and uniform, when reducing by 15% cement consumption, its anti-permeability performance and comprcssive strength the most even have with control sample
Being improved, internal structure is closely knit, and distribution of pores is good；In document it is also mentioned that: there are some researches show concrete has 15-30% left
Right cement is incomplete aquation, only serves filling effect, it is impossible to reacted by effectively dispersion, actually belongs to water more than needed
Mud；Study carefully the mechanism of action of its CTF Concrete synergist product exactly: can quickly improve the dispersibility of cement granules, promote coagulation
Effect of soil high efficiency water reducing agent, improves the performance of fresh concrete, thus in Concrete Structure each thing mutually between attachment force, reach
Purpose is strengthened to xoncrete structure.
But CTF Concrete synergist has the requirement of harshness at aspects such as volume, limited degree and curing conditions, restricted
In cement and the adaptability of concrete, itself and rubble, sand and the proportioning stringent especially of water, prior art being pointed out, impact is mixed
The principal element of solidifying soil crack resistance is cement, but have ignored substantial amounts of sand in formula and crack resistance can be caused material impact, due to
The modulus of fineness of sand is little, and water requirement reduces, and has, on setting time, the contribution that can not ignore shortening, and in CTF concrete potentiation
On the basis of agent incorporation concrete has been greatly shortened setting time so that concrete drastically condenses, CTF Concrete synergist
Have little time to disperse cement granules more than needed and promote water reducer performance, be easily generated that slump-loss is big and bleeding rate reduces, condensation time
Between the problem such as shortening, make the effect of CTF Concrete synergist not give full play to, the concrete performance obtained is difficult to ensure.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of strong concrete, gives full play to CTF Concrete synergist
Effect improve the dispersibility of cement granules, and solve the problems such as shortening setting time, it is ensured that the excellent slump, workability
And comprcssive strength.
