The present applicant will describe the present invention in detail as follows. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals designate corresponding parts throughout the several views. The description of which will be omitted.
The present invention relates to a process for producing a curable composition comprising 15 to 40% by weight of an industrial by-product-containing uncrosslinked material containing an aluminosilicate-based industrial by-product, a sulfate-based stimulant and a calcium-based industrial byproduct, 10 to 25% by weight of a room temperature curing accelerator, 45 to 70% by weight of silica sand.
At this time, when the content of the industrial byproduct-free cement binder is less than 15% by weight, the bimbe performance deteriorates to deteriorate the workability. When the content is more than 40% by weight, the strength- Which is undesirable.
The above industrial by-product non-cement bound materials may contain aluminosilicate-based industrial by-products, sulfate-based stimulants, and calcium-based industrial by-products. The aluminosilicate-based industrial by-products serve to enhance acid resistance and develop long-term strength. Specific examples thereof include iron-smelting slag fine powder, copper smelting slag fine powder, stainless steel slag fine powder or a mixture thereof, The acid resistance of the mortar can be appropriately controlled by controlling the content thereof, and specific examples thereof include calcium sulfate, aluminum sulfate, sodium sulfate, or a mixture thereof. The calcium-based industrial by-products may be paper ash, fly ash, red mud dry powder, slaked lime, anhydrous gypsum or a mixture thereof. The calcium-based industrial by-products are preferably high-calcium industrial by-products having a free lime content of 20 to 60 wt% By containing a large amount of free lime, calcium hydroxide (Ca (OH) 2 ) is produced by reacting with water, and the initial strength is exhibited by the pottery effect. And may be characterized by reacting with release from calcium hydroxide to produce calcium silicate hydrate (CSH) and calcium aluminate hydrate (CAH). As a result, when the high calcium-based industrial by-product is used as a mortar composition, hydration reaction mechanism similar to cement can be exhibited without use of cement, and high strength can be exhibited. In addition, the aluminosilicate-based industrial by-products have a densely impervious acidic coating on the surface of the particles while being in contact with water, and when the cement is initiated due to the sulfate-based stimulant, the strength- You can. In this case, it is preferable that the non-cement based binder used in the industrial by-products is contained in an amount of 40 to 70% by weight of aluminosilicate-based industrial by-products, 10 to 40% by weight of a sulfate-based stimulant, and 15 to 30% by weight of calcium-based industrial byproducts.
The room temperature curing accelerator may be mixed in an amount of 10 to 25% by weight, preferably 10 to 20% by weight. When the content of the room temperature curing accelerator is less than 10% by weight, And if it is contained in an amount exceeding 25% by weight, contact with moisture will undesirably lead to re-slurrying of the cerium-free binder used in the industrial by-products.
The room temperature curing accelerator is used to control the curing rate. It can be used by adjusting the amount of the curing agent in accordance with the construction conditions. The room temperature curing accelerator may be 30 to 50% by weight of phosphate, 40 to 60% by weight of magnesium oxide and 0.5 to 10% . The phosphoric acid salt may be ammonium phosphate, potassium phosphate, sodium phosphate or a mixture thereof. When the content is less than 30% by weight, the workability is poor. When the content is more than 50% by weight, . In the case of the oxidized mark nematicide, if the content is less than 40% by weight, the strength is lowered. If the content is more than 60% by weight, it is difficult to secure the pot life time. And if it is more than 10% by weight, it is difficult to exhibit strength, which is not preferable. At this time, the retarding agent may be tartaric acid, borax, dispersion, sodium gluconate or a mixture thereof.
The main reaction mechanism when the room temperature curing accelerator is used is as follows.
MgO + NH 4 H 2 PO 4 + 5H 2 O → NH 4 MgPO 4 · 6H 2 O
MgO + NH 4 H 2 PO 4 → NH 4 MgPO 4 · H 2 O
NH 4 MgPO 4 .6H 2 O? NH 4 H 2 PO 4? H 2 O + 5H 2 O
The functional additive may be at least one selected from the group consisting of a polymer, a reinforcing fiber, a shrinkage reducing agent, a surfactant and a calcium hydroxide, and the content of the functional additive is preferably 0.05 to 10% by weight.
By improving the adhesion between the powders, the polymer can remarkably improve the strength of the cement mortar, which makes it possible to ensure the viscosity of the cement mortar composition, And at the same time securing liquidity. Specific examples thereof include xanthan gum, gum arabic, styrene-butadiene resin, polymethyl methacrylate-butyl acrylate resin, polyvinyl acetate ethylene resin, polystyrene-butyl acrylate resin, carboxymethyl cellulose, hydroxypropyl methylcellulose or Or a mixture thereof, but is not limited thereto.
The reinforcing fiber is included in the cement mortar composition so that moisture is supplied to the cement mortar composition to prevent drying shrinkage, plastic contraction, and the like by zooming. That is, the reinforcing fibers increase the binding force of the mortar and at the same time, by absorbing unnecessary moisture of the mortar and sufficiently supplying water during the curing period of the mortar, the reinforcing fibers are usefully used for preventing drying shrinkage, plastic shrinkage and the like of the mortar And it is preferable to use organic fibers including nylon fibers, but the present invention is not limited thereto.
The surfactant may be at least one selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants and amphoteric surfactants, preferably sodium dodecyl sulfate, linear sulfonic acid alkylbenzene alkyl benzene sulphonate, sodium lauryl ether sulfate, sodium xylene sulphonate, sodium naphthalene sulphonate, cetyl trimethyl ammonium chloride (CTAC), polyquaternium But are not limited to, polyquaternium-11, polyethylene glycol monostearate, ester quaternary ammonium salt, or a mixture thereof.
The slaked lime is intended to react with the aluminosilicate-based industrial by-products to improve initial strength and long-term strength.
The cement mortar composition of the present invention can be mixed with 45 to 70% by weight of the silica sand, which serves as a filler in the cement mortar composition and influences the strength, workability and durability of the cement mortar according to the particle size give. At this time, the size of the silica sand is not particularly limited, but the strength, workability and durability of the silica sand can be controlled by controlling the size of the silica sand according to the application. If the content of the silica sand is less than 45% by weight, the effect of suppressing the shrinkage of the room temperature curing accelerator may be insignificant and the amount of drying shrinkage may increase. If the content is more than 70% by weight, It is not desirable.
