Description
Technical field
The present invention relates to construction material technical field of concrete additives, more particularly to a kind of novel pre-stressed hole path pressure grouting
Material and preparation method thereof.
Background technology
The conventional prestress hole path pressure grouting material design of in the market is only mostly to meet JTG/T F50-2011《Highway bridge and culvert
Construction technique normalizing》Construction requirement, and have ignored prestress hole path pressure grouting material itself performance, economy, environmental protection and consider.
My company sets out in line with the environmentally friendly machine purpose for building environment-friendly enterprise and exploitation series, is developed using improvement phosphorus ore slag
A kind of function admirable, economy, the novel pre-stressed hole path pressure grouting material of environment-friendly type obtain the present invention, and it has following characteristics：
At present, China's rock phosphate in powder reserves and basic unit price are respectively 4,100,000,000 tons and 10,000,000,000 tons, and 27.14% He in the whole world is accounted for respectively
21.28%.Guizhou stores substantial amounts of phosphate rock resource, there is the title of Chinese phosphorus all, and phosphorus ore slag is to produce the Industry Waste produced during phosphate fertilizer
Slag, takes a large amount of land resources and rainy season harmful substance meeting dissolution fluorine, phosphorus etc. and causes environmental pollution.Development and utilization phosphorus energetically
Slag is for active response country and place on the policy of the recycling of Industry Waste past heritage, environmental protection, adjustment industry knot
The effects such as structure upgrading, reform are self-evident.
1 ton of yellow phosphorus of production will discharge 7 to 10 tons of phosphorus ore slags, China's phosphorus ore slag per annual emissions at least more than 8,000,000 tons,
Phosphorus ore slag is as a kind of industrial residue, and cost is very low, and my company is located Kweiyang in addition, and distance opens sixties kilometers of phosphorylcholine group,
Apart from nineties kilometers of Wengfu group, cost of transportation is cheap, for substituting cement as a kind of one of main component of the present invention,
Greatly reduce the integrated cost of the present invention.
Phosphorus ore slag is mainly used in replacing partial cement clinker, phosphorus ore slag and added for a long time in building trade, industrial residue
Gas brick, concrete admixture, region to be developed are more, and the phosphorus ore slag in Guizhou is mainly Water Quenching Slag, vitreum content 80% to 90%,
Its main component calcium oxide, silica account for the 86.74% to 94.85% of phosphorus ore slag, have good activity strong for the present invention
Degree.
Phosphorus ore slag is that building trade generally acknowledges to act on have the class material for slowing down cement setting time with cement, namely can not be many
Plus the reason for one of, so as to reach the effect of slow setting, i.e., in the present invention relative to patent CN201210075021.0,
CN201210258236.6、CN201310165783.4、CN201310318374.3、CN201410698930.9、
CN201610290630.6 etc. is need not to increase retarder composition and its cost produced, has reached environmental protection and economic height
Spend use value.
The content of the invention
The invention aims to obtain function admirable, environmental protection, economic construction material, and proposition is a kind of new pre-
Stress hole path pressure grouting material and preparation method thereof.
The present invention proposes a kind of novel pre-stressed hole path pressure grouting material, it is characterised in that each component is according to proportion by weight

It is preferred that, the industrial residue is at least one in phosphorus ore slag, fluorgypsum, slag.
The present invention also proposes a kind of preparation method of prestress hole path pressure grouting material, it is characterised in that comprise the following steps：
S1：Raw material enter storehouse and carry out raw material detection, carry out prestress hole path pressure grouting material experiment before production every time, and fine setting component is matched somebody with somebody
Than to guarantee to obtain the excellent present invention, accurately measuring satisfactory each component raw material material；
S2：By the Portland cement measured in S1 and industrial residue, mineral admixture, plastic expansion agent, swelling agent, watt
Gram rubber powder input batch mixer is persistently stirred；
S3：After S2 is stirred 15 ~ 20 minutes, S1 is put into successively and measures water reducer, defoamer, air entraining agent, preservative, each component is thrown
The material time completed no less than 2 minutes, was persistently stirred after all finishing 30 minutes；
S4：Sampling carries out prestress hole path pressure grouting material experiment after the completion of S3, and whether detection production sample properties of product reach expection
Good effect；
S5：The product for being up to the examples representative of Expected Results carries out packed sealing, deposits in the environment for drying ventilation.
Beneficial effect：In the present invention, 1, while excellent performance is reached introduce industrial residue, the environmental protection for having height
Value, phosphorus ore slag cost it is relatively low in addition with it is nearer apart from company, cost is substantially reduced.
2nd, phosphorus ore slag is applied already in building material industry, but does not see related application in prestress hole path pressure grouting material,
The activity index of phosphorus ore slag is higher, there is good accretion to grouting material intensity.
3rd, phosphorus ore slag can also slow down Portland cement the initial condensation time, without increasing other retarder,
The integrated cost of prestress hole path pressure grouting material is greatly lowered.
