Description
Technical field
The present invention relates to hydraulic engineerings and building material technical field, more particularly, to a kind of manufacturer of sand consolidating agent
Method.
Background technique
Sand consolidating agent is filled in mining area cave and is reinforced, the filling of building foundation pit, and dam body, slope protection add in hydraulic engineering
Gu being widely applied in the infrastructures such as filling and goods yard basis, road bed.Existing consolidating agent mostly use lime and
Cement, although can reach the intensity of design requirement, its is water-fast, antiseepage, corrosion resistance are poor, and slow curing, early strength are low,
And need to consume a large amount of cement resources.There are also use sand to consolidate for the difference that is applicable to that fine aggregate, stone are coarse aggregate preparation
The polytypic high strength and waterproof soil solidifying agent of peering elephant, although effect is preferable, high production cost.
Yellow River basin Huayuankou section sluggish flow, sediment deposition cause riverbed to be raised, influence flood control safety in riverbed.This
The silt particle to deposit a bit is therefrom swum over to downstream clay grain content and is gradually increased based on shale Extra-fine sand.Part setting pot is normal at present
Year siltation, the silt digged up are nowhere stacked again, if can be developed and used, make engineering construction material, it will
Generate good Social benefit and economic benefit.
Summary of the invention
The purpose of the present invention is to provide a kind of method for manufacturing sand consolidating agent using the Yellow River shale Extra-fine sand, the party
Method is simple and easy, energy-saving and environment friendly, has good Social benefit and economic benefit.
To achieve the above object, the present invention can take following technical proposals:
The manufacturing method of sand consolidating agent of the present invention, it is characterised in that: include the following steps:
The first step will enter in calcining furnace after shale Extra-fine sand preheating and drying, calcine two hours under 1050 ~ 1150 DEG C of high temperature, so
It is quickly cooled down (time being cooled to room temperature is no more than 1 hour) afterwards, it is spare to be ground to 200 ~ 300 mesh fine powders；
Second step, will made from the first step calcining shale Extra-fine sand fine powder and miberal powder, cement by 70 ~ 80%:5 ~ 10%:10 ~ 25% it
Weight percent is uniformly mixed after weighing, and obtains sand consolidating agent finished product.
The shale Extra-fine sand is the siltation sediment of Yellow River basin Huayuankou section, and main component is quartz (content >
45%), plagioclase and potassium feldspar；Shale ingredient is clay particle, and content is generally between 5 ~ 25%.
If clay particle content is lower than 10% in actual measurement shale Extra-fine sand, need first to mix 5 ~ 10% clay particle, it will
It after mixing, then carries out calcination processing with shale Extra-fine sand.
The S95 miberal powder that the miberal powder is obtained after being crushed using basic rock (such as lime stone).PO can be used in cement used
42.5 cement, clinker, 52.5 grade portland cements or 52.5 grade ordinary portland cements.
When pre-manufactured product (such as preparation ecological slope protection hexagon hollow brick, six rib block of gutter diversion trench and ecological slope protection),
Medium-fine sand and tap water is added by proper proportion in the consolidating agent that makes of the present invention and (or meets concrete mixing water requirement
Water source), it mixes and stirs under room temperature, molding of vibrating, high-intensitive prefabrication can be obtained.
The advantage of the invention is that raw material is available locally, transportation cost is saved, to the Yellow River middle and lower reaches shale Extra-fine sand
Reasonable utilize the siltation for slowing down middle and lower reaches riverbed again；Preparation method is simple, energy-saving and environment friendly；It is prepared by the present invention simultaneously
Consolidating agent is made pre-manufactured product after can also being mixed and stirred in proportion with the medium-fine sand in sediment, to the comprehensive benefit of raw material
With can produce good Social benefit and economic benefit.
