The using method of a kind of cement based microdilatancy crack repairing mortar that is mixed with porcelain powder waste material that the present invention proposes, concrete steps are as follows:
Accurately take the above-mentioned cement based microdilatancy crack repairing mortar that is mixed with porcelain powder waste material preparing, first water is added to stirrer, along with blade of stirrer rotates, mortar is at the uniform velocity dropped into stirrer.After stirring, can construct.Amount of water is the 15%-25% of product weight of the present invention.
Product of the present invention is a kind of cement based microdilatancy crack repairing mortar that is mixed with porcelain powder waste material, and its feature is as follows:
1. in the present invention, adopting ordinary Portland cement and aluminosulfate cement is as main bonding component.Two kinds of cement are used in conjunction with, can reach the effect of mutual supplement with each other's advantages: utilize aluminosulfate cement the hardening effect of silicate cement to be improved to the early strength of silicate cement; Utilize silicate cement to make up the poor defect of aluminosulfate cement later strength; Utilize aluminosulfate cement to react the ettringite generating with calcium hydroxide and gypsum and play shrinkage-compensating or microdilatancy.
2. porcelain powder waste material, slag powders and flyash, as adulterant, form plural gel system together with two kinds of cement.Adopt porcelain powder waste material, slag powders and flyash combined addition, give full play to three's activity, the early strength to whole system and later strength can play very large effect.
Porcelain powder waste material has higher pozzolanic activity, the calcium oxide that it and hydrated reaction of cement produce reacts, significantly reduce calcium oxide amount of crystals a large amount of very strong hydrated calcium silicate gels of gelling that produce, play promoter action for the raising of the closely knit and later strength of whole system structure.
Breeze composition is similar to cement clinker, wherein SiO 2, CaO and Al 2o 3total content approximately reaches 90%, and activity is higher, is a kind of the most frequently used concrete admixture, and the particularly raising of later strength of strength development that the hydrated calcium silicate gel that its aquation generates and drated calcium aluminate gel can Promotion systems, plays plural gel effect.
Flyash is a kind of material with lateral reactivity material.The calcium hydroxide reaction that the silicon-dioxide in flyash and aluminum oxide produce can be with hydrated cementitious time generates new stable hydrated calcium silicate and thereby drated calcium aluminate has improved the intensity of crack repairing mortar and the ability of chemical resistance of concrete; And fly ash grain particle shape is complete, smooth surface, quality densification, can play water-reduction, compaction and homogeneous effect, thereby improves the pumpability of cement based crack repairing mortar in the time of construction.
3. to select fineness be (10-20) object fine quartz sand to quartz sand, makes the mortar can be for repairing the less crack of diameter, and the little quartz sand of fineness contributes to improve the mortar intensity in each length of time simultaneously.
4. can reduce water consumption adding of high-performance water reducing agent, improve fluidity of slurry and stability, improve mortar workability, contribute to improve mortar strength, reduce drying shrinkage.
5. hardening accelerator adopts Quilonum Retard, can improve early strength, avoids early stage damage inactivation.
6. swelling agent adopts the one in calcium oxide expansion agents or sulplo-aluminate class swelling agent, can in hydrated cementitious, process of setting, generate a large amount of swelling property crystal water compound ettringite, be filled in mortar micropore, produce appropriateness and expand, the string stress producing while offsetting mortar hardening.
7. make mending mortar having under larger flowing property condition adding of water-holding agent, do not occur bleeding and segregation phenomenon.
8. defoamer adopts silicon-dioxide-mineral oil defoaming agent, can reduce the air content of fresh mortar, heightens slurry density, thereby improves mortar strength.
9. binding agent adopts latex powder, can improve the adhesive property of mortar, makes mending mortar and crack well-bonded.
Product of the present invention is using ordinary Portland cement, aluminosulfate cement, porcelain powder waste material, slag powders, flyash as gelling material, for gathering materials, and add high efficiency water reducing agent, hardening accelerator, swelling agent, water-holding agent, defoamer and binding agent to be prepared from quartz sand.Its preparation technology is simple, fresh mortar mobility and good water-retaining property, and early strength development is fast and later strength is high, and volume microdilatancy is impervious and wear resistance is good, is applicable to the crack repairing that width is less than 50mm, has good economic benefit and social benefit.
