Abstract
Present invention proposition is a kind of, and using quartz sand and slag as the cement grout material of aggregate, it is prepared by cement, quartz sand, slag, silicon ash, water reducer and defoamer, and the mass fraction proportioning of each component is：100 parts of cement, 40 parts of quartz sand, 60 parts of slag, 1~10 part of silicon ash, 0.3~0.6 part of water reducer, 0.2~0.4 part of defoamer.The beneficial effects of the present invention are：（1）Cement grout material of the present invention, by proportion optimizing, is prepared by quality raw materials.Ample supply and prompt delivery, and raw material is easy to get, non-volatile, no dirty evil, processing is prepared simply, and cost is cheap；（2）Slag largely is used in the present invention, realization is turned waste into wealth, the purpose of energy-saving and emission-reduction；（3）Performance indications of the present invention meet JC/T 986 2005《Cement grout material》Standard requirement.
Description
Technical field
The present invention relates to a kind of cement grout material, more particularly, to a kind of cement grout using quartz sand and slag as aggregate
Material, belongs to New Building Materials field.
Background technology
Cement-based grouting material be it is a kind of by cement be main binder materials, then be subject to appropriate aggregate, and on a small quantity
Additive and other materials, by industrialized production and with rational gradation composition dry-mixed material.Strength cement-based grouting material because
It has many excellent performances such as good mobility, self compacting ability, high epistasis, ungauged regions at normal temperatures, in Equipment Foundations
Back-grouting on, in the anchoring of foundation bolt, many aspects such as the reinforcing of concrete and repairing all have it is extremely extensive
Using.The building material industry standard JC/T 986- that the National Development and Reform Commission of China promulgated cement grout material in 2005
2005《Cement grout material》, require in standard cement grout material 1d, 3d, 28d compression strength be greater than respectively 22MPa,
40MPa、70MPa；Initial flow degree and 30min fluidity retentions are greater than 260mm and 230mm respectively；1d vertical expansion ratios
More than 0.020%.
Chinese patent CN1039788A discloses a kind of preparation method of super high-strength cement material, and its compression strength can reach
To 150MPa, but material does not have mobility in itself, and process system is special hot-pressing, does not possess field application bar
Part；Chinese patent CN1271696A discloses a kind of high-strength super-fluidized expanding cement grout, and its 28d compression strength can reach
To 90MPa, but 1d compression strength only has 20MPa.
The aggregate used in cement grout material is with SiO mostly in the market2For the quartz sand of main component.Quartz
Sand is a kind of nonmetallic mineral that quartz is process after crushing.As China's building trade flourishes, quartz sand
The problem of having faced over-extraction and unstable supply, the substitute for finding quartz sand are extremely urgent.Slag is steel enterprise
Industry is in waste residue caused by manUfaCtUre of pig iron.With the development of China's steel and iron industry, China produces nearly hundred million tons of slags every year.Slag has
There is the characteristics of wear-resisting, high rigidity, freeze-thaw resistance, yield are big, cost is low, be a kind of potential Building wood with premium properties
Material.If can be made full use of, not only protected environment, and for increasingly rare non-renewable building material
It is a kind of supplement.
The content of the invention
The present invention for the purpose of steel slag resource comprehensively utilizes and carried out the national policy of environmental protection and waste utilization, using slag as
Cement grout material aggregate uses, and a kind of strength cement-based grouting material using quartz sand and slag as aggregate is made, while meet JC/T
986-2005《Cement grout material》It is required that.
A kind of cement grout material using quartz sand and slag as aggregate proposed by the present invention, it is characterised in that its by cement,
Quartz sand, slag, silicon ash, water reducer and defoamer are prepared, and the mass fraction proportioning of each component is：100 parts of cement,
40 parts of quartz sand, 60 parts of slag, 1~10 part of silicon ash, 0.3~0.6 part of water reducer, 0.2~0.4 part of defoamer.
The cement is to meet GB175-2007《Common portland cement》In the type portland cements of P II, intensity etc.
Level is 52.5R；
The modulus of fineness of the quartz sand is 1.3~1.5；
The slag be by electroslag by hydraulic discharged slag method obtained by, slag that particle diameter is 0.3mm and particle diameter are 0.6mm
Slag respectively account for 30 parts；
The silicon ash specific surface area is in 20000~27000m2/kg；
The water reducer is polycarboxylic acid series high efficiency water reducing agent, and water-reducing rate is 25%~30%；
The defoamer is dimethyl silicone polymer.
The present invention has following advantages effect compared with prior art：
1st, cement grout material of the present invention, by proportion optimizing, is prepared by quality raw materials.Ample supply and prompt delivery, and raw material is easy
, non-volatile, no dirty evil, processing preparation is simple, and cost is cheap；
2nd, slag largely is used in the present invention, realization is turned waste into wealth, the purpose of energy-saving and emission-reduction；
3rd, performance indications of the present invention meet JC/T 986-2005《Cement grout material》Standard requirement.
