Description
Technical field
The invention belongs to concrete field, be specifically related to a kind of two high-titanium blast furnace slag mortar of mixing micro mist.
Background technology
High-titanium blast furnace slag is to climb steel ordinary blast while smelting vanadium titano-magnetite, a kind of fine and close slag with some strength that the melted gangue of generation naturally cooling or water-cooled in air form.With ordinary blast slag ratio, titanium dioxide in steel climbing high slag (TiO2) content is up to 20%～24%, calcium oxide content is lower, the grain slag of this raw material production belongs to non-active material, therefore, climbing steel has the titanium slag of more than 5,500 ten thousand tons not to be utilized so far, and it takes up an area thousands of mu, and annual also with the bed drain purge increase of 3,000,000 tons, climb steel and be faced with the situation of deslagging nowhere.On the other hand, Panzhihua City need consume a large amount of rubbles, sand every year, and exceedingly exploitation has destroyed vegetation, causes soil erosion.Can titanium slag be fully utilized, and not only has influence on and climb steel, the socioeconomic Sustainable development of Flos Bombacis Malabarici, and to saving natural resources, reduce engineering cost, and protection Upper Yangtze River ecotope etc. all has great importance.
High-titanium blast furnace slag is all containing a certain amount of ground-slag after the operations such as fragmentation, screening, and its powder containing quantity generally fluctuates in 8～15% scopes, the regulation that artificial sandstone powder containing quantity is less than to 7% higher than national standard.For reaching standard-required, manufacturer adds that washing step is to wash out ground-slag after being everlasting and sieving, and remaining is high-titanium blast furnace slag slag sand.The ground-slag that washes out treated micro mist, and if utilize this micro mist, whether the performance of mortar is caused to disadvantageous effect, the checking of still needing; Meanwhile, in mortar, add flyash, lime putty etc., be mixed with mixing fly-ash mortar, whether improve the performance of mortar, also need verification experimental verification.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of two high-titanium blast furnace slag mortars of mixing micro mist that reduce production costs and can improve mortar performance.
The technical solution adopted for the present invention to solve the technical problems is: two high-titanium blast furnace slag mortars of mixing micro mist, by every cubic metre of mortar, cement 220～310kg, high-titanium blast furnace slag slag sand 1450～1750kg, flyash 20～100kg, lime putty 0～80kg and high-titanium blast furnace slag composite micro-powder 100～350kg.
Described high-titanium blast furnace slag composite micro-powder refers to take high-titanium blast furnace slag as main raw material, the micro mist making after ball milling.High-titanium blast furnace slag composite micro-powder granularity is-200 orders.
Wherein, in above-mentioned mortar, by every cubic metre of mortar, cement 250～270kg, high-titanium blast furnace slag slag sand 1580～1690kg, flyash 60～80kg, lime putty 50～70kg and high-titanium blast furnace slag composite micro-powder 150～300kg.
Wherein, in above-mentioned mortar, by every cubic metre of mortar, cement 260kg, high-titanium blast furnace slag slag sand 1610kg, flyash 70kg, lime putty 60kg and high-titanium blast furnace slag composite micro-powder 193kg.
Wherein, in above-mentioned mortar, described high-titanium blast furnace slag composite micro-powder is containing high-titanium blast furnace slag micro mist, slag micro powder and flyash micro mist, the Chong Liang ︰ composite micro-powder gross weight > 0.6 of high-titanium blast furnace slag micro mist.
The preparation of high-titanium blast furnace slag composite micro-powder: by formulated after levigate, the weight of high-titanium blast furnace slag accounts for composite micro-powder gross weight more than 60% by high-titanium blast furnace slag, slag and flyash.
It will be appreciated by persons skilled in the art that in high-titanium blast furnace slag composite micro-powder and also can add other a small amount of slag micropowders, as long as the weight of high-titanium blast furnace slag accounts for composite micro-powder gross weight more than 60%.
Slag of the present invention is the slag that conventional steel-making is discharged, and according to the type of furnace, can be divided into converter slag, open hearth slag, electric furnace slag.
The invention has the beneficial effects as follows: the present invention uses high-titanium blast furnace slag, only, on the basis of excavation, broken slag, sieve, calculate every m
3cost-saving 4～6 yuan than common river sand, high-titanium blast furnace slag slag sand, can obtain the economic benefit of 40～600,000 yuan if produce every year 100000 cubes of slag sands.In addition, the two fly ashs of the present invention and high-titanium blast furnace slag composite micro-powder, can improve intensity and workability, when meeting < < Code for design of masonry strucres > > (GB50003-2001) requirement, further improve its performance, within 7 days, intensity can reach 7.0MPa, and within 28 days, intensity can reach 15.4MPa, and slip resistance can reach 0.72MPa.
Embodiment
Below by embodiment, the present invention is further described.
The two high-titanium blast furnace slag mortars of mixing micro mist of the present invention, by every cubic metre of mortar, cement 220～310kg, high-titanium blast furnace slag slag sand 1450～1750kg, flyash 20～100kg, lime putty 0～80kg and high-titanium blast furnace slag composite micro-powder 100～350kg.
