Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of existed concrete bridge secondary hydration is to enhance intensity
Reinforcing agent.
Background technique
With the progress of modernized society of China, as city, traffic, water conservancy, agricultural construction main material concrete
Also more and more generally received by society, concrete usage amount is huge, and national concrete admixture usage amount is about 20,000,000,000 within 2016
Ton, concrete are 2,000,000,000,000 sides, and concrete usage amount becomes the first in the world, but China borderland is wide, and climate change is larger, sand
Stone aggregate and cement quality are irregular, and construction level is even more that there are many problems, and the following concrete quality problem is not
It is not troubling, the problems such as especially the northern area of China morning and evening temperature difference is larger, and dusty wind weather is more, and Maintenance in Winter is difficult, is prominent
Out, by generation concrete bracing, the qualitative problems of construction such as low strength are even more to enable numerous concreter authors puzzled,
Later period substantially makes it difficult for concrete strength to reach design requirement using remedial measure, can only use all kinds of reinforcement and strengthenings
Means guarantee the safety of concrete structure, not only laborious bothersome, it is also difficult to fundamentally solve Concrete intensity insufficient and bring
Concrete durability problem.
Concrete early stage such as because temperature is lower or concrete in the missing of liquid phase can all cause the decrease of hydrated cementitious or stop
Only, while causing concrete shrinkage crack, so the maintenance measure for reinforcing concrete early stage heat and moisture preserving is indispensable, but
Inevitably some vertical members and thin component are asked because it conserves difficulty with the strength reduction for being easy appearance affected by environment
It inscribes more serious.Seek it is a kind of can promote existed concrete bridge secondary hydration, improve compression strength concrete intensifier become must
So.
Summary of the invention
Present invention solves the technical problem that be to provide a kind of existed concrete bridge reinforcing agent, by permeating, promoting the strong, moisturizing
Saturated limewater is brought into inside concrete by method, in the case where guaranteeing humidity, so that concrete is generated secondary hydration, to reach
Improve the purpose of intensity.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is as follows: a kind of existed concrete bridge reinforcing agent, institute
With raw material according to following weight part ratio: 55-200 parts of saturated limewater, 0.1-2 parts of diethylene glycol (DEG), 0.1-1.5 parts of triethanolamine, Portugal
0.05-2 parts of grape sodium saccharate, 0.1-2.5 parts of water-reducing agent.
It is raw materials used according to following weight part ratio: 80-150 parts of saturated limewater, 0.1-1 parts of diethylene glycol (DEG), triethanolamine
0.1-1 parts, 0.1-2 parts of sodium gluconate, 0.1-2 parts of water-reducing agent.
The water-reducing agent is polycarboxylate.
The water-reducing agent is the aqueous solution of base allyl polyethenoxy ether, concentration 80-90wt%.
It is tested as follows using technical solution of the present invention: by diethylene glycol (DEG), triethanolamine, sodium gluconate and water-reducing agent
It is added spare after saturated limewater is uniformly mixed placement at room temperature 48 hours.
Test wall thickness 200mm, area 40m2, the configuration proportion of C35 concrete is cement 270kg, miberal powder 90kg, flyash
50kg, at any time 1180kg, sand 690kg, additive 8.2kg, water 175kg.C35 is pumped into placement layer by layer, vibrating spear vibrates, and pours
11-19 DEG C of temperature, continuous to brush reinforcing agent of the present invention, first 7 days uninterrupted to brush, to guarantee that metope is wet, remaining be daytime not
Interruption is brushed, the maintenance of night plastic film Moisture conservation, during which finds that initial test wall water absorption is big, brushing interval time is 10
Minute, later period water absorption is gradually reduced, and 30 days core boring samplings are that brushing number substantially remains in 15 times/day, and core diameter is
100mm passes through cutting, drying, sulphide mastic filling-in processing, a detection test data before the detection of core sample are as follows:
Find out that effect is obvious after brushing the reinforcing agent by above-mentioned test data, and with the extension for brushing the time, intensity is gradually
It improves, early strength was increased speed higher than the later period, had concrete surface to start aquation in early stage reinforcing agent, gradually entered coagulation
Native internal, the seepage-resistant grade of C35 is P6, and when entering inside concrete, difficulty is increasing, and inside concrete can promote coagulation
The Strong oxdiative calcium of native aquation is also being reduced, and the following reinforcing effect also becomes slower and slower, so the present invention carries out initial stage
Brushing is very necessary, while as conditions permit can extend concrete enhancing curing time.The knot of 72h is supported by writing to 85 DEG C
Fruit sees that the ability that reinforcing agent diffuses into inside concrete at high temperature has significant increasing compared with coming with untreated concrete result
By force, reinforcing agent is completely into inside concrete is arrived after 72h, and the aquation of concrete obtains in wet condition at high temperature
It further strengthens, reinforcing effect reaches optimum state.
As described above, compared with the prior art, the invention has the beneficial effects that: the present invention of the invention solves mixed
Existed concrete bridge effectively can be improved it by secondary hydration by the problem of low strength caused by solidifying soil early curing is improper
Intensity, easy for construction, energy conservation and environmental protection both ensure that the intensity of concrete, also improve the durability of concrete.
Application principle of the invention is that reinforcing agent is mainly main medium by saturated limewater, by adding scattering and permeating
Agent brings saturated limewater into inside concrete, and by the N key on its molecule come acceleration of hydration, sodium gluconate is main for agent of promoting the strong
The moisture in air is adsorbed as a kind of concrete moisture retention agent to increase concrete surface humidity, and polycarboxylate dehydragent master
Cooperate diffusion agent to make the least water consumption of cement generate hydration reaction.As the temperature rises, the reinforcing agent
Effect can become apparent from, and for the aquation continuity for guaranteeing cement, answer the continual maintenance for doing concrete.
