Description

A kind of is to gather materials and the dry-mixed mortar of filler with waste stone dust in stone mining and processing plant
Technical field
The invention belongs to civil engineering material technical field, being specifically related to a kind of is to gather materials and the dry-mixed mortar of filler with waste stone dust in stone mining and processing plant.
Background technology
There is a large amount of exploitation of stone processing enterprises on ground such as China Fujian, Guangdong, Zhejiang, Shaanxi, Shanxi, Guangxi, Shandong, Xinjiang, these enterprises processed for national economic development exploitation be used for the stone material of structure load-bearing and decoration in a large number after, destroyed massif, leave over down simultaneously the waste solid that is difficult to dispose, promptly a large amount of stone flours.Competent authorities of country and local government call on urgently and must find practical measures, the stone flour that effectively utilizes these to do great damage over against environment.
The waste stone dust that produces by exploitation of stone processing, its particle diameter is generally 0-50mm, wherein the above particle of 5mm can be used for concrete coarse aggregate, and the following fine aggregate of 5mm is when being used for concrete, often concrete performance is brought disadvantageous effect, concrete production enterprise would rather adopt natural sand as fine aggregate.Therefore, the comprehensive utilization of resources of the following stone flour of 5mm remains a great problem.In fact, building mortar can suitably reduce for the specification of quality of sand.
For accelerating the energy-saving and emission-reduction of Building Trade in China, promote the construction of harmonious society, on June 6th, 2007, six ministries and commissions such as China Department of Commerce, the Ministry of Public Security, the Ministry of Construction, State Administration of Quality Supervision, Inspection and Quarantine and Environmental Protection Administration unite and have issued " about forbid the on-the-spot notice that stirs mortar working at part city time limit " (merchant sends elsewhere [2007] No. 205), will be with the time in 3 years, promote the general goods mortar step by step in 127 cities, the whole nation, that is to say, the building mortar in these cities will be the same with concrete, carry out centralized production and supply.
Summary of the invention
The object of the present invention is to provide a kind of is to gather materials and the dry-mixed mortar of filler with waste stone dust in stone mining and processing plant.
What the present invention proposed is to gather materials and the dry-mixed mortar of filler with waste stone dust in stone mining and processing plant, is made up of 0.08m-5mm waste stone dust, 0-0.08mm waste stone dust, cement, flyash, metakaolin, calcium hydroxide and water-retaining admixture, and the weight ratio of each component is:
0.08mm-5mm waste stone dust 100
0-0.08mm waste stone dust 2-17
Cement 20-50
Flyash 8-15
Metakaolin 5-12
Calcium hydroxide 1.5-4.5
Water-retaining admixture 1-9.
The preferable weight ratio of each component is:
0.08mm-5mm waste stone dust 100
0-0.08mm waste stone dust 3-12
Cement 25-50
Flyash 9-14
Metakaolin 6-10
Calcium hydroxide 2-4
Water-retaining admixture 1-7.
Among the present invention, described water-retaining admixture be wilkinite, sepiolite, diatomite, montmorillonite or ether of cellulose be one in the batch production product formed of starting material to several, it is that grey is to the beige powder.
Preparation method of the present invention is: by aforementioned each part by weight weighing each component, 0.08-5mm waste stone dust, 0-0.08mm waste stone dust, cement, flyash, metakaolin, calcium hydroxide and water-retaining admixture added in the mixing machine successively stir, the time is 5-7min.Obtain institute's invention product.
Among the present invention, the 0.08mm-5mm waste stone dust obtains after adopting the waste stone dust of exploitation of stone source mill to sieve, and its silt content is controlled in 3%.0.08mm-5mm waste stone dust is an inert particle, it plays the skeleton function that gathers materials in dry-mixed mortar.0-0.08mm waste stone dust obtains after adopting the waste stone dust of exploitation of stone source mill to sieve, its silt content is controlled in 5%.0-0.08mm waste stone dust is an inert particle, it plays the effect that filling concrete, flyash and metakaolin are piled up the space, back in dry-mixed mortar, helps to reduce the shrinking percentage of dry-mixed mortar and strengthens its weather resistance.Cement adopts a kind of in 42.5 grades of ordinary Portland cements or the 32.5 grades of ordinary Portland cements.Cement is a kind of as gelling material, will issue the unboiled water reflection in the situation that mixing water exists with flyash, metakaolin, forms hydraulicity hydrated product, and will gather materials bonds together, and is formed with the integral body of intensity.Flyash adopts a kind of in II level F class and the C class, requires its loss on ignition to be not more than 8%.Flyash has good secondary pozzolanic reaction activity, it is in mortar adds after water is smeared (building) 7-28 days, can a large amount of hydration reactions take place with the calcium hydroxide that uses in calcium hydroxide in the hydrated cementitious product and the present invention's prescription, form hydrated calcium silicate gel and ettringite, improve the intensity of mortar.Metakaolin is the product of kaolin after calcining under the 600-900 ℃ of condition, and its main chemical compositions is the SiO that has chemical reactivity at normal temperatures and pressures 2And Al 2O 3Its effect in product of the present invention is similar to flyash on the one hand, and on the other hand, because it has vesicular structure, help to improve the cohesiveness and the water-retentivity of mortar mixture, because its existence, the consumption of water-retaining admixture can suitably reduce in the formula for a product of the present invention, and the benefit of bringing is the cost that influences mortar strength and reduce mortar within reason.Calcium hydroxide is technical grade product, requires calcium oxide and magnesium oxide total content greater than 65%, and volume stability is qualified, and 0.125mm tails over and is not more than 3%.The existence of calcium hydroxide is very helpful to the activity that excites flyash and metakaolin, can improve the early strength of product of the present invention, and opposing is cracking in early days.The effect of water-retaining admixture is the cohesiveness that the effect of and Van der Waals force strong by bridge improves cement-flyash-metakaolin slurry system, guarantee that the mortar mixture does not produce layering, segregation and bleeding in depositing process, and guarantee mortar smear in the process smooth property and smear after anti-tenesmus, the existence of water-retaining admixture also helps to improve the cohesive strength between mortar and the basic unit.
The present invention catches the city to produce and apply the good chance of commodity mortar, adopt waste stone dust in stone mining and processing plant for gathering materials and filler, develop workability and water-retentivity is good, intensity, contract with dry rate, the satisfactory dry-mixed mortar of durability index, not only gather materials in this mortar and all adopt waste stone dust, but also utilize part barren rock powder as filler, dry-mixed mortar recycling 750-550Kg waste stone dust per ton, with an enterprise that produces 300000 tons of dry-mixed mortars per year is example, ten thousand tons of waste stone dust of annual recycling 22.5-16.5, its economy, environment and social benefit are quite obvious.
The present invention for a kind of be to gather materials and the dry-mixed mortar of filler with waste stone dust in stone mining and processing plant owing to utilized the waste stone dust that accounts for mortar product weight 55%-75%, have the good feature of environmental protection and ecological property.The not only sharp wasted energy power of this dry-mixed mortar is strong, feature of environmental protection excellence, and also its water retention is good, but application property is strong, intensity, durability index height.The shrinking percentage of this mortar is low, has certain splitting resistance.Product application scope of the present invention is wide, generally is applicable to plastering, build by laying bricks or stones and floor treatment of various civil engineering works.
