Preferably, described admixture specifically how based water reducer, described admixture accounts for the 5%-20% in described exciting agent.
By one or more technical scheme of the present invention, the present invention has following beneficial effect or advantage:
The invention provides a kind of method manufacturing wall body brick, mainly make use of slag and sintering desulfuration ash this kind of Industrial Solid refuse be that raw material is to manufacture wall body brick, and the Composition Control of wall body brick is existed: slag 30-40 part, sintering desulfuration ash 10-20 part, slag micropowder 10-20 part, cement 0-8 part, exciting agent 1-3 part, yellow ground 10-20 part, Guamishi 30-40 part, make the wall body brick good stability manufactured, high (the 28 days ultimate compression strength 16.6MPa of intensity, folding strength 5.3MPa), good product quality, surface crack-free, wear resistance is good, all technical reaches national wall body brick standard for building.In addition, owing to employing refuse as raw material, comprehensive utilization and the environment protection of resource can be realized, efficiently solve the process problem of slag and sintering desulfuration ash.
Further, what select due to slag of the present invention is the slag that particle diameter is no more than 5mm after crushing-magnetic selection, without the need to carrying out abrasive dust, drying, ageing process process again, reduces the manufacturing cost of wall body brick.
Accompanying drawing explanation
Fig. 1 is the method flow diagram manufacturing wall body brick in the embodiment of the present invention.
Embodiment
In order to make the application the technical staff in the technical field more clearly understand the application, below in conjunction with accompanying drawing, by specific embodiment, technical scheme is described in detail.
In embodiments of the present invention, disclose a kind of method manufacturing wall body brick, mainly make use of slag and sintering desulfuration ash for raw material, add that wall body brick made jointly by other auxiliary materials, therefore, the composition of this wall body brick comprises (ratio of weight and number):
Slag 30-40 part, sintering desulfuration ash 10-20 part, slag micropowder 10-20 part, cement 0-8 part, exciting agent 1-3 part, yellow ground 10-20 part, Guamishi 30-40 part.
Specifically, what slag was selected is the slag that particle diameter is less than or equal to 5mm after crushing-magnetic selection, and such slag, without the need to again through abrasive dust, drying, ageing process process, has saved cost of manufacture.In addition, the specific surface area of slag micropowder is more than or equal to 450m
2/ kg, and the Vitrea weight percent content in slag micropowder is more than or equal to 85%.Vitreum, is a kind of form of non-crystalline solids material, is also called amorphous body.In a liquid, fluid molecule is more closely stacked.The motion of fluid molecule becomes torpescence along with the reduction of temperature, and along with the increase of fluid viscosity, place-exchange motion is gradually frozen and solidify, and this state is vitreous state.With liquid type seemingly, its inner particle arranges the regularity not having crystal strict like that, near zero pour, particle arrangement is " short-range order ", and continue cooling, viscosity is large, the speed that molecule (or atom) overline is arranged reduces greatly, hinder crystallisation process, finally make the arrangement of short-range order " freeze " to get off, form vitreum.Vitreum content determines in breeze the substances content that can participate in reacting.
In addition, described exciting agent is made up of gypsum and admixture.Described admixture specifically how based water reducer, admixture accounts for the 5%-20% in exciting agent.
The performance that parts by weight due to composition, composition are compared to wall body brick all has a significant impact, the combination of heterogeneity, and the produced wall body brick of the parts by weight of different compositions has diverse performance, therefore, the present invention for the composition of wall body brick and the control stricter than having of the weight fraction of composition, such as, controls the composition of wall body brick for (ratio of weight and number):
Slag 30-40 part, sintering desulfuration ash 10-20 part, slag micropowder 10-20 part, cement 0-8 part, exciting agent 1-3 part, yellow ground 10-20 part, Guamishi 30-40 part.Adding the principle of slag micropowder is be the vitreum of main component by calcium, silicon, aluminium, magnesium oxide, after dissociating under certain conditions, calcium, silicon, aluminium, magnesium plasma enter in solution, combine with the calcium oxide in slag, magnesium oxide and gypsum, generate silicate cement compound and sulplo-aluminate hydrate, if breeze adds too high by low for the degree making vitreum completely be excited, the reaction density of the hydrate generated is also lower, can not meet the requirement that calcium oxide in slag, magnesium oxide and breeze form silicate cement compound, cause hydrate structural damage.Can the vitreous structure of slag be dissociated activated slag after gypsum is water-soluble, and participate in water generation reaction sulplo-aluminate hydrated product.Add-on too much can make the liquid base of hydration reaction spend height, is unfavorable for the calcium oxide on slag top layer, magnesium oxide stripping, directly affects the stability of aquation structure.Adding of admixture can reduce water consumption, improves product strength.Yellow ground, Guamishi use as filler aggregate.
Please refer to Fig. 1 below, specifically introduce the manufacture method of the wall body brick that the embodiment of the present invention relates to.
S1, by described sintering desulfuration ash, described slag micropowder, described cement, described exciting agent according to respective proportioning mix and blend, forms dryness mixed powder.
S2, is mixed into described slag, described yellow ground, described Guamishi in described dryness mixed powder, then adds water to stir to form slurry.
S3, by described slurry injection wall body bricks die, and is pressed into the idiosome then demoulding at normal temperatures.Specifically, normal temperature condition generally refers to outdoor normal temperature 10 DEG C-40 DEG C.
S4, solidifies described idiosome to form described wall body brick.Specifically, after idiosome is formed, then by idiosome maintenance 7 days under field conditions (factors), and need to keep idiosome surface wettability, then place use of can dispatching from the factory after 28 days, the main purpose of placement is that the time of placement is based on practical situation in order to allow idiosome carry out solidifying formation wall body brick.
In sum, the present invention mainly make use of slag and this kind of Industrial Solid refuse of sintering desulfuration ash is that raw material is to manufacture wall body brick, and the Composition Control of wall body brick is existed: slag 30-40 part, sintering desulfuration ash 10-20 part, slag micropowder 10-20 part, cement 0-8 part, exciting agent 1-3 part, yellow ground 10-20 part, Guamishi 30-40 part, make the wall body brick good stability manufactured, high (the 28 days ultimate compression strength 16.6MPa of intensity, folding strength 5.3MPa), good product quality, surface crack-free, wear resistance is good, all technical reaches national wall body brick standard for building.In addition, owing to employing refuse as raw material, comprehensive utilization and the environment protection of resource can be realized, efficiently solve the process problem of slag and sintering desulfuration ash.
Further, what select due to slag of the present invention is the slag that particle diameter is no more than 5mm after crushing-magnetic selection, without the need to carrying out abrasive dust, drying, ageing process process again, reduces the manufacturing cost of wall body brick.
