Description
Technical field
The present invention relates to building material field, be specifically related to a kind of reinforced cementitious additive of bridge floor and preparation method thereof.
Background technology
Along with social development, scientific progress, improving constantly of mankind's actual life demand, especially in China, due to economical flourish, it is necessary to substantial amounts of capital construction, to meet modernization construction,
Bridges in Our Country is numerous, and concrete bridge deck pavement disease highlights, irregular chicken-wire cracking, relatively regular longitudinally, laterally crack and more serious breaking, and the broken ring at expansion joint and bridge floor sink, railing and the damage of footpath system etc. have a strong impact on the use of bridge,
At present, along with bridge construction is carried out in high gear, bridge floor material quality requirement is improved by bridge further, and increasing cement additire is applied in above-mentioned construction.
There is the aspects such as intensity, parameter, mix and construction and there are problems in existing concrete and additive, concrete admixture selection and use on there is additive improper use, there are mistaken ideas in design concept, codes and standards location there is the problems such as deviation. Major technique has the drawback that additive can play great positive effect in concrete, depends on that we are to its selection and using method. If selection improper use, will result in accident resulting from poor quality of projects. As air entraining agent can reduce the intensity of cement-based material, but air entraining agent can make concrete water amount reduce, and makes the concrete water bleeding sedimentation rate after construction reduce simultaneously, also can reduce the expansion owing to alkali causes. Once being referred to as the entringite of " cement bacillus ", reason is it is the arch-criminal lost efficacy because of sulphate corrosion of concrete; Can finding later, entringite can compensate for concrete shrinkage.
The invention aims to meet modern architecture industry needs, it is provided that a kind of reinforced cementitious additive of bridge floor, so that it is more convenient to construct, bridge construction quality is higher.
Summary of the invention
It is an object of the invention to overcome prior art concrete bridge deck pavement disease to highlight, irregular chicken-wire cracking, relatively regular longitudinally, laterally crack and more serious breaking, the broken ring at expansion joint and bridge floor sink, railing and the damage of footpath system etc. have a strong impact on bridge use defect.There are problems in existing concrete and additive in intensity, parameter, mix and construction etc.
To achieve these goals, technical scheme is as follows:
The reinforced cementitious additive of a kind of bridge floor is by following parts by weight:

Material therefor in the present invention
The volume of silica flour is typically between 5%��8%, the volume of flyash is typically between 10��40%, silica flour is more expensive, activity is bigger, so silica flour is generally used for the high-strength concrete of more than C60, for promoting Behavior of Hardened Cement Paste and the boundary strength gathered materials in concrete, silica flour is very big due to its specific surface area, concrete water consumption can be increased when volume is bigger, make concrete become very glutinous.
When its water demand ratio of flyash is less than 100%, mixes and concrete can improve concrete service behaviour and reduce water consumption.
Due to the tricalcium silicate, dicalcium silicate and the ferrous aluminate isoreactivity mineral that contain in slag and cement is similar, there is hydraulic gelling; Simultaneously slag rubble have that density is big, intensity is high, rough surface, good stability, the wear-resisting feature being firmly combined with good endurance and cement;
Initiator, also known as radical initiator, refer to that an easy decomposes of class becomes the compound of free radical (i.e. primary group of free radicals), can be used for causing alkene class, the radical polymerization of double; two vinyl monomer and copolymerization, it is also possible in crosslinking curing and the high molecular crosslink reaction of unsaturated polyester (UP). Temperature requirement according to polyreaction selects initiator.If high-temperature initiator is used in mesophilic range polymerization, then decomposition rate is too low, and makes polymerization time extend; If middle temperature initiator is for high temperature range polymerization, then decomposition rate is too fast, and initiator consumes too early, in the oligomerization conversion ratio stage with regard to stopped reaction.
The effect of retarder is to allow concrete keep the good slump and fluidity. Retarder is a kind of additive reducing cement or Gypsum Fibrosum hydration rate and the heat of hydration, prolongation setting time. Use retarder can delay the process of initial set. Mix in commerical ready-mixed concrete retarder, in order that extend the hydration and hardening time of cement, makes fresh concrete can keep plasticity in a long time, thus regulating the setting time of fresh concrete. Multiple different functional monomer can be combined by polymerization technique, and the length of strand, the size of molecular weight and distribution can be controlled, therefore this kind of retarder can instruct it to synthesize by MOLECULE DESIGN thought, obtains the retarder that combination property is ideal.
Described water reducer is one or more in wood calcium water reducer, naphthalene series high-efficiency water-reducing agent, polycarboxylic acid series high efficiency water reducing agent, melamine system water reducer. Reduce concrete water consumption, promote concrete strength.
Polycarboxylate dehydragent, also known as super plasticizer, is the high molecular weight water soluble polymer of a kind of " intelligent ". It has many excellent performances: high diminishing, high damages of collapsing durable, low, high-strength morning are by force and environmental protection. Existing polycarboxylate water-reducer major part is (methyl) acrylic acid minor comonomer and methanol polyoxyethylene ether acrylate polymeric monomer copolymer or maleic anhydride minor comonomer and the big class of allyl alcohol polyethenoxy ether polymeric monomer copolymer two. They have similar comb shaped structure, by being sized the mol ratio of monomer, it is possible to regulate the density of comb; By adjusting the molecular weight of polymeric monomer, it is possible to adjust the length of comb to meet the needs of various Development of HPC.
The present invention is used adopts allyl polyethenoxy ether sulfate as a kind of novel sodium polycarboxylate water reducer of polymeric monomer synthesis, the main chain of this water reducer is the same with other water reducer, many highly polar groups on main chain, it is adsorbed on cement particle surface, having many ehter bonds on side chain, it freely can stretch between cement granules, when cement granules is close to each other, the steric restriction effect of physics is produced, it is prevented that the cohesion of cement granules between polymer molecular chain; Branch terminals at it also has epistasis group, and increment also can be adsorbed on cement particle surface, and it plays link and supporting role between different cement granules; Same cement granules plays arch bridge supporting role, due to electrostatic and supporting role, prevents the cohesion of cement granules, it have been experienced that cement is had good dispersive property and retentivity by it, the concrete slump is had good retentivity.
The present invention adopts minor comonomer (methacrylic acid, maleic anhydride) and polymeric monomer (allyl polyethenoxy ether sulfate, molecular weight is 1000) mol ratio to be 3.5:1; Polymerization temperature: 85 �� 3 DEG C; Polymerization time: react 4 hours; Initiator amount: 4%. Polymerization reaction time extend, flowing degree of net paste of cement is gradually increased, when polymerization reaction time be 4 or 5 little constantly, flowing degree of net paste of cement reaches maximum; Economically consider, the response time be decided to be 4 hours proper.
Concrete fills a certain amount of extender, concrete expansion rate during wet curing is made to reach 1.5 �� 10-4��2.0 �� 10-4, the compressive pre-stress of 0.2MPa��0.7MPa can being produced in xoncrete structure, compensating temperature shrinkage and dry shrinkage, thus avoiding structure crack.
The present invention can effective reinforcement bridge bridge floor, to ordinary cement, complex cement early, later strength all have good chemi-excitation effect.
