Description
Technical field
The present invention relates to a kind of concrete admixture, especially a kind ofly can improve significantly concrete early stage and later strength, shorten the construction period, have again good diminishing simultaneously, protect the concrete nanometer diminishing super instant coagulant of moulding, hinder rust and stability.
Background technology
At present, in order to improve concrete performance, to satisfy the concrete construction needs, various concrete admixtures arise at the historic moment, such as hardening accelerator, water reducer, retardant, pumping agent and frostproofer etc.The Main Function of hardening accelerator is to accelerate hydrated cementitious speed, improve early age strength of concrete and later strength is not made significant difference, can shorten striking time, improve form cycling rate and implement as early as possible prestressed stretch-draw etc., be widely used in the urgent engineering of construction period (salvaging etc.), reinforced concrete prefabricated and prestressed concrete engineering.Yet existing hardening accelerator function singleness at most also only has early strong and diminishing function, does not have resistance rust property and exist to protect to mould and the problem of poor stability.
Be the patent of invention of CN101200354 such as China Patent Publication No., a kind of concrete super instant coagulant is disclosed, consisted of by inorganic salts accelerating component, organic accelerating component and diminishing component, although setting and harden quickly, improve each age strength of concrete and (can reach 40% of 28 days the strength of standard curings in 1 day, can reach 75% of 28 days the strength of standard curings in 3 days, concrete crushing strength can improve 17% in 28 days), but the amplitude that each age strength improves is little, and concrete protect plasticity can be short of.
China Patent Publication No. is the patent of invention of CN101941813A, a kind of concrete early strength water-reducing agent is disclosed, formulated by saltcake, wooden calcium and coal ash, although also possessed early strong and diminishing function, the concrete strength that equally also exists each length of time improves problem limited and that protect plasticity can be short of.
Summary of the invention
The present invention is in order to solve the existing above-mentioned technical problem of prior art, a kind of increase substantially concrete early stage reach later strength, shortening construction period are provided, have again good diminishing simultaneously, protect the concrete nanometer diminishing super instant coagulant of moulding, hinder rust and stability.
Technical solution of the present invention is: a kind of concrete nanometer diminishing super instant coagulant, it is characterized in that by accelerating component, diminishing component, resistance rust component, slow setting component and regulate component consisting of, and the mass percent of each component is as follows:
Accelerating component 46%～52%;
Diminishing component 26%～32%;
Resistance rust component 6%～15%;
Slow setting component 4%～5%;
Regulate component 6%～8%;
Described accelerating component is three kinds or four kinds in sal epsom, sodium sulfate, Sodium Nitrite, trolamine, Sulfothiorine, tri-isopropanolamine, the calcium formiate;
Described diminishing component is a kind of in naphthene sulfonic acid series high-efficiency water-reducing agent, the carboxylic acid water reducing agent;
Described resistance rust component is a kind of in calcium nitrite, nitrocalcite, potassiumchromate, the tin protochloride;
Described slow setting component is a kind of in Sunmorl N 60S, the citric acid;
Described adjusting component is the nanometer water-ground limestone.
The effect of cooperatively interacting of each component of the present invention all has preferably suitability to ordinary Portland cement, Portland blastfurnaceslag cement, compared with prior art, has following advantage:
1. epistasis early: (intensity can reach more than 90% of design strength in 24 hours to improve significantly concrete early strength, intensity can reach more than 100% of design strength in 36 hours), and later strength also improves (intensity can reach more than 120% of design strength in 28 days) significantly;
2. water reducing ability: have very high water-reducing rate (can reach 30%), compare with blank concrete slump, can improve more than the 10cm;
3. protect plasticity: solved protect mould and excessive slow setting between contradiction, effectively control concrete slump-loss, keep concrete flowability, improve its pumping power;
4. hinder the rust property: have good resistance rust effect, can effectively stop chlorion to the corrosive nature of reinforcing bar, prevent steel bar corrosion, prolong the work-ing life of buildings;
5. stable: as owing to added nano material, to reduce concrete water bleeding and segregation, improved concrete workability.
