Description

Sulfur polymer binder (SPO) concrete moldings {product method of SPB concrete manufacture}

The present invention is to produce a concrete molding by adding a sulfur polymer binder (SPB) to the aggregate, and relates to a method for producing a sulfur polymer binder (SPB) concrete molding.

In general, existing cement is cheaper, but when CO ₂ is generated to make cement, it accelerates global warming and there is no way to recycle construction waste after use, and the strong alkalinity of cement pollutes soil or groundwater, which adversely affects the environment. It is not environmentally friendly because of the harmful effects of heavy metals in cement. In addition, there is a disadvantage that the corrosion is easy in chemical environments such as acid rain and sea water.

     For example, Patent Registration No. 10-1107290 has a lane block, the stop block to have a lower layer of 80 to 90% of the total thickness, and a surface layer of 10 to 20% of the thickness, the surface layer is 70% of the aggregate water 30 In the total weight of%, aggregate is 28% silica sand with 0.1 ~ 0.5mm particle size, 9% silica sand with 1 ~ 1.4mm particle size, 11% silica fume, 18% sand, 33% portant cement, admixture 1% of the mixture, the lower layer is 75% aggregates, 25% of the total weight of water, the aggregate is 15% volcanic stone of 6 ~ 8mm particle size, 10% of 8mm grain size gravel, 25% of 13mm grain size gravel A parking block having high strength is disclosed, which is manufactured by mixing 24% sand, 25% blast furnace cement, and 1% admixture.

     In addition, Korean Patent Publication No. 10-2010-0092561 discloses a compounding step of mixing a material consisting of gravel, sand, cement with water at a predetermined ratio; Injecting the blended material into a block mold; A releasing step of releasing a block from the block mold; A drying step of transferring the deformed block to a curing chamber and drying it; And impregnating the dried block with soil, water, and immersing the mixed block in a mixture containing seeds to take out soil, water, and seeds in the dried block. It is open.

However, the prior arts produce a large amount of CO ₂ during production, and incineration or landfill is used as the main raw material of cement that causes environmental pollution, and also because the appropriate filler is not used, it is easy to corrode in chemical environment, durability, water resistance There was a disadvantage of being low.

     On the other hand, sulfur generated as a by-product of petroleum refining is used in various industrial fields, but it is reaching the limit of securing large demand and increasing utilization. Therefore, high value-added sulfur polymer binder (SPB) is manufactured through reforming to consume a large amount of by-product sulfur, and SPB concrete using this is more durable, corrosion-resistant, and It has excellent characteristics in chemical resistance, water resistance and freeze shrinkage.

Therefore, the present invention has been made to solve the above problems, it is possible to recycle by using SPB as a cement substitute material that generates a large amount of CO ₂ during production and incinerated or buried to cause environmental pollution and corrosion in chemical environment It is to provide a method for producing a sulfur polymer binder (SPB) concrete molding is not.

The present invention relates to a method for producing a sulfur polymer binder (SPB) concrete molding, comprising: mixing a mixture of sulfur polymer binder (SPB), gravel, sand, filler; Melting and compressing the mixture at a temperature of 120 ° C. to 150 ° C .; And injecting the melted and compressed mixture into a mold, followed by vibration and compression.

Therefore, the present invention can reduce the consumption of cement by using SPB in place of cement can reduce the CO ₂ generated during cement manufacturing, which can slow down the global warming phenomenon, and also harm the health emitted from cement. It can be eliminated, and it is water, chemical and corrosion resistant, and can be recycled as a thermoplastic material to solve the waste problem, and there is a significant economic advantage.

The present invention relates to a method for producing a sulfur polymer binder (SPB) concrete molding, comprising: mixing a mixture of sulfur polymer binder (SPB), gravel, sand, filler; Melting and compressing the mixture at a temperature of 120 ° C. to 150 ° C .; And injecting the melted and compressed mixture into a mold, followed by vibration and compression.

     In addition, the mixture is characterized in that with respect to 16 to 24 parts by weight of sulfur polymer binder (SPB), 37 to 45 parts by weight of gravel, 35 to 43 parts by weight of sand, 1 to 8 parts by weight of filler.

     In addition, the filler is characterized in that any one of ocher, fly ash, talc, charcoal powder, silica fume, blast furnace slag.

The present invention will be described in detail with reference to the accompanying drawings. 1 is a process chart for manufacturing the SPB concrete molding of the present invention, Figure 2 is a SPB concrete specimen photo experimented for the present invention, Figure 3 is a SEM micrographs photo according to the heating temperature of the SPB concrete of the present invention {(a) 130 degreeC, (b) 140 degreeC, (c) 150 degreeC}.

     The present invention relates to a method for manufacturing SPB concrete, SPB concrete can be utilized in the construction and civil engineering concrete structural materials that require durability and corrosion resistance, such as sidewalk blocks, water and sewage pipes and coastal blocks, artificial reefs, marine structures, For accurate mixing of the SPB concrete used, aggregate aggregate gravel and sand are mixed, and the sulfur compound binder (SPB) and filler, which are binders, are mixed with the mixture. The mixture is heated to dissolve the SPB, then injected into a mold, vibrated and compressed to obtain a molded product.

     Looking at the SPB concrete manufacturing method applied to the present invention, the correct compounding ratio is first mixed with 37 to 45 parts by weight of gravel, 35 to 43 parts by weight of sand, SPB 16 to 24 parts by weight, filler 1 to 8 parts by weight, mixed, each material Mix well so that they are evenly distributed. The mixture thus mixed is heated and compressed to about 120 ° C. to 150 ° C., and then injected into a mold having a shape of a relief block, a sidewalk block, and the like, and then vibrated and compressed to obtain a molded product after cooling at room temperature. At this time, the injection pressure in the mold is suitable for 180bar, vibration and compression plays a role in compacting the SPB concrete.

     On the other hand, when the gravel in the SPB concrete is less than 37 parts by weight, the strength is lowered, and when it exceeds 45 parts by weight, the strength is stronger, but the bonding strength is relatively poor. The sand is bonded by the SPB and the filler, and the bonded sand fills the void space between the gravel and the gravel to increase the overall strength and increase the bonding strength. When it is less than 35 parts by weight, the strength and the bonding strength are decreased and 43 parts by weight If it is exceeded, the strength and the bonding force worsen. If the SPB is less than 16 parts by weight, the bonding strength is lowered. If the SPB is more than 24 parts by weight, the strength is relatively lowered. And the filler basically acts as a filler to fill the empty space in concrete, and has the inherent physical properties of the physical properties according to the type of filler, and generally less than 1 part by weight, the bonding strength falls, when the filler exceeds 8 parts by weight The strength is relatively low.

In addition, the temperature for heating and compressing the mixture is about 120 ° C. to 150 ° C., when the temperature is less than 120 ° C., the SPB does not melt well. Adjust to 150 ° C.

     An embodiment of the present invention will be described as follows.

     Sulfur polymer binder was purchased from Micropowder Co., Ltd., and the particle size is thick so that the size is about 1 ~ 2mm using a mixer. In the case of gravel, the powder is about 6 ~ 12mm, and the sand is dried. As the instructor does not contain salt and water, the size should be 0.5 ~ 3mm.

     The basic composition of SPB is 16 to 24 parts by weight, gravel is 37 to 45 parts by weight, sand is 35 to 43 parts by weight, the mixture is heated, and the temperature of the press mold is raised to 120 to 150 ° C. After dissolution, the mixture is injected and then vibrated. SPB concrete specimens were prepared by compression.
