Abstract
The invention relates to the field of concrete additive processing, and especially relates to a synthetic method of a composite functional-type additive. The synthetic method employs the following technical scheme: taking a naphthalene-series water reducer and an aliphatic water reducer as reactants, taking sodium gluconate, sodium dodecyl sulfate and water as dropwise adding compositions, and performing mixing and synthesis to prepare the composite functional-type additive. The prepared composite functional-type additive aims at the problems that the naphthalene-series water reducer is too fast in slump loss and easy to crystallize in winter, and through combination, crystallization is reduced and the disadvantage of too fast slump loss is solved.
Description
Technical field
The present invention relates to concrete admixture manufacture field, refer in particular to complex function type admixture and synthetic method thereof.
Background technology
Development along with concrete technology, concrete multiple performance is all had higher requirement, such as mobility is large, protect and collapse that the time is long, hydration heat is low, intensity is high and good endurance etc., and energy efficient as far as possible, reduces costs and the economic requirement such as rapid construction.Engineering practice proves, concrete admixture can not only make concrete obtain premium properties, also can meet numerous different engineering construction demands, so concrete admixture has become requisite component in concrete simultaneously.
At present, concrete admixture market is used more admixture for naphthalene water reducer and aliphatic water reducing agent.Naphthalene water reducer low price, but when temperature is spent lower than 15, there is the problems such as loss of slump is too fast, easy crystallization in winter, water-reducing rate is general; Aliphatic high-efficiency water reducing agent is wide to cement suitability, obvious to concrete reinforced effects, little loss of slump, and low temperature is without sulfate crystal phenomenon, but that its shortcoming is color is excessively red, a lot of stirring stations are all reluctant to use, and cannot meet concrete construction requirement.Therefore be badly in need of a kind of admixture to overcome the shortcoming of above-mentioned two kinds of admixtures.
Summary of the invention
The present invention aims to provide that a kind of the two compoundly obtains a kind of complex function type admixture and improve concrete degree of mobilization by naphthalene water reducer and aliphatic water reducing agent, protects collapsing property, has solved the phenomenons such as crystallization, color be ugly.
A preparation method for complex function type admixture, it comprises the following steps:
1) mix stages: 600～650 parts of 300～350 parts of naphthalene water reducers and aliphatic water reducing agents are added in reactor, then reactor is put into water-bath be warmed up to 50～55 ℃, constant temperature stirs 30～40 minutes;
2) synthesis phase: to reactor, add 40～45 parts of Sunmorl N 60Ss for controlling concrete contraction percentage ratio, 0.3～0.5 part of air entrapment agent, constant temperature stirs 30～40 minutes.Air entrapment agent consumption too much can affect concrete strength, and cross and affect at least concrete workability,
Described air entrapment agent is sodium lauryl sulphate, rosin or sodium laurylsulfonate.
A complex function type admixture, its preparation method according to above-mentioned complex function type admixture is prepared from.
The present invention is by by the synthetic composite additive obtaining of naphthalene water reducer and aliphatic water reducing agent, it is compared single water reducer of planting and has solved the too fast weakness of loss of slump, overcome again the problems such as aliphatic water reducing agent color is ugly, greatly improved the performance of water reducer, saved production cost.
Embodiment
Below preferred embodiment of the present invention is described in detail.
embodiment 1:
1) mix stages: naphthalene water reducer 300g and aliphatic water reducing agent 600g are added in reactor, then reactor is put into water-bath be warmed up to 50 ℃, constant temperature stirs 30 minutes;
2) synthesis phase: add Sunmorl N 60S 45g, sodium lauryl sulphate 0.5g to reactor, constant temperature stirs 30 minutes;
embodiment 2～6
Adopt the preparation method identical with embodiment 1, the respective value that difference is to use respectively addition, reaction times, the temperature of each compositions different in each step listed in table 1 to replace embodiment 1 to adopt.
Table 1
The properties data that concrete after the concrete modifying admixture modification making with embodiment 1-6 is surveyed under the environment of 0 degree are as table 2:
Table 2
As can be seen from Table 2, the concrete properties data after the composite functional admixture modification making with embodiment 1-6 are all better than GB, and its water-reducing rate is high, bleeding rate is low, and air content is low, and sodium sulphate content is low, concrete strength is higher, and concrete percent crystallization in massecuite is lower, and performance is more superior.
Claims (3)
1. a preparation method for complex function type admixture, it comprises the following steps:
1) mix stages: 600～650 parts of 300～350 parts of naphthalene water reducers and aliphatic water reducing agents are added in reactor, then reactor is put into water-bath be warmed up to 50～55 ℃, constant temperature stirs 30～40 minutes to fully dissolving;
2) synthesis phase: add 40～45 parts of Sunmorl N 60Ss, 0.3～0.5 part of air entrapment agent to reactor, constant temperature stirs 30～40 minutes.
2. the preparation method of complex function type admixture according to claim 1, is characterized in that described air entrapment agent is sodium lauryl sulphate, rosin or sodium laurylsulfonate.
3. a complex function type admixture, it is that the preparation method of complex function type admixture according to claim 1 and 2 makes.
