The particle diameter of flyash or mica powder is 100-300 μm;
The particle diameter of rice straw powder and peanut hull meal is 0.5-1mm.
The preparation technology of above-mentioned concrete material comprises the steps:
Meerschaum and zeolite being mixed according to the mass ratio of 1:1, then put into crusher in crushing, scrap rates is 200r/min, the broken time is 5min, and the material after then crushing is placed in ball milling in ball mill, and ball milling speed is 100r/min, Ball-milling Time is 10min, obtains compound A;
Water, Epocryl, polypropylene fibre, dodecylbenzene sodium sulfonate, sodium monofluorophosphate, calcium stearate are compared mix homogeneously according to the quality of 10:5:3:2:1:1, it is then heated to 70 DEG C, add and the mica powder of calcium stearate equal in quality, it is heated to 90 DEG C, 200 r/min stirring reaction 30min, obtain compound B;
Adding in agitator tank by rice straw powder, peanut hull meal, bean cake and water by the mass ratio of 1:1:1:3, be heated to 80 DEG C, then 200 turns/min stirs 90min, obtains compound C;
Portland cement, fluvial sand, flyash, compound A, compound B and water in mass ratio 60-90: 30-50: 20-30:12-18: 7-12: 40-60 are mixed, 200r/min stirs 5min, obtain slurry, then adding in slurry by compound C, 100r/min stirring 3min obtains concrete;
Described compound C is the twice of compound A.
The present invention obtain beneficial effect be primarily but not limited to following some:
Compared with prior art, concrete of the present invention is through lot of experiments and exploration, change the raw material composition of existing concrete, part material is modified simultaneously, the advantage such as its concrete prepared possesses that mechanical strength is big, light weight, length in service life, corrosion-resistant, aging resistance and easy care;The present invention, in the raw material of concrete, adds resin and polypropylene fibre, adds the performances such as the intensity of concrete, elasticity, wearability;The present invention, by adding the raw materials such as meerschaum, agricultural waste material and flyash, improves foaming effect, on the premise of not reducing intensity so that electric pole more light weight, and stability is more preferable, saves the raw materials such as cement simultaneously;Have employed substantial amounts of cheap raw material in concrete formulation of the present invention, material combination is reasonable, greatly reduces the cost of product, preparation technology simple possible, is suitable for large-scale production, can be widely applied to the field such as shaft tower and Lou Ti.
