A kind of normal portland cement for pavement of road and production method
The present invention relates to a kind of ordinary Portland cement and production method applicable to the different kinds of roads pavement concrete.
At present, because the develop rapidly of communications and transportation cause, the construction task of high-grade highway is also more and more heavier, and also just more and more supply falls short of demand for road bitumen, and price is rise trend.Therefore, country has formulated a series of policy and has encouraged various places to increase disposable input, and build is long duration of service, the cement concrete pavement that maintenance cost is low.Be used for the particularly cement on advanced road road surface of pavement of road, must have very high wear resistance and very little contract with dry rate, stipulate in standard GB 13693-92 " road silicate cement " technical requirements for this reason: aluminic acid salt face (C in the cement clinker
3A) must be less than 5.0%, iron phase (C
4AF) must be greater than 16.0%, and the wear resistance of regulation cement must not represent greater than 3.60Kg/m with abrasion loss
2, 28 days contract with dry rate of cement must not be greater than 0.10%.Performances such as the folding strength of existing ordinary Portland cement and Portland blast, wear resisting property and shrinking percentage are not as road silicate cement, and producing road silicate cement by GB will significantly increase the difficulty of production technique, increase production cost.Wear resistance is good, shrinking percentage is little so research and produce, and it is imperative to be used for the ordinary Portland cement that road engineering uses." method of silicate cement grog burnt by copper mine slag burden " that Chinese patent CN1050859A proposes, be that employing Wingdale, clay are main raw material, correction material is high-al clay, flyash, sandstone, stone coal slag, and process for calcining is to use complete black meal, the dying fire operation.It is characterized in that replacing iron powder (sulfate slag) with the copper mine slag, replace fat coal with thermal value 3000-4000 kilocalorie/Kg inferior coal, the purpose of this method has been to overcome the limitation that can only use fat coal in the existing production technology.CN1078220A discloses a kind of " furnace phosphorus slag and blast-furnace slag are prepared burden and produced the method for cement clinker ", and it is to add electric furnace phosphoric slag and blast-furnace slag batching whole (or part) replacement clay, P when raw meal proportioning
2O
5Meter is controlled at 0.2-0.6%, and the add-on of blast-furnace slag is counted 5-20% with raw material weight, and the cement that adopts this method to produce can not meet quality and the characteristic requirement of road with special silicate cement fully.
The object of the present invention is to provide a kind of wear resistance height, contract with dry rate little, and can be applicable to the ordinary Portland cement and the simple production method of different kinds of roads pavement concrete.
The present invention when producing batching, behind the furnace phosphorus slag or furnace phosphorus slag and copper mine slag of introducing 3-15%, helps improving the burn-ability of raw material owing to adopting Artificial Control Portland clinker iron phase to form, and because P

6A
2F), and both mol ratios are 1: 1, and the chemical formula of this sosoloid is C
5A
1.5F, tested and put into practice prove test shows no matter be rotary kiln and machine shaft kiln, after mixing 3-15% electric furnace phosphoric slag or furnace phosphorus slag in the raw material and adding the copper mine slag, normal incinerating Portland clinker, its iron phase all is C
4AF-C
6A
2F sosoloid, thus under the condition that does not change other production technique, can produce C
4The contract with dry rate of AF＞16.0%, C3A＜5.0% is little, the Portland clinker that wear resistance is high, and with the cement that this cement clinker grinds, its contract with dry rate＜0.01%, wear rate＜3.6%kg/m
2, can be used for the different kinds of roads pavement concrete.Cement clinker is carried out extraction back residues (iron phase) such as Whitfield's ointment-methanol solution and acetate solution through chemical analysis results, its CaO: Al

2The existence of F is Fe just
2O
3The tetrahedron of ligancy reduces and the octahedra result who increases.
The present invention adopts conventional equipment just can produce the ordinary Portland cement that can be used for pavement of road, thereby solved the problem of difficulty of special production road cement, having sulfate resistance, wear resistance is good, contract with dry rate is low characteristics through the cement that the present invention produced, is a kind of product that is suitable for.
Below the present invention is described in detail.
The present invention is to be major ingredient with conventional raw material limestone, clay, correction material is that sandstone, iron powder, coal are fuel, in the raw material preparation, introduce furnace phosphorus slag or furnace phosphorus slag and copper mine slag with inorganic ion, it mixes scope at 3-15%, if when electric furnace phosphoric slag and copper mine slag mixing match, its electric furnace phosphoric slag is 1-2 with the scoriaceous ratio of copper: 1, to increase the solid solution capacity of aluminum oxide in iron phase, thereby form tetracalcium aluminoferrite and iron two aluminic acids six calcium sosoloid, because iron phase C
4AF-C
