Definitions
- the present invention relates to a concrete composition for underwater construction. More specifically, the present invention is an aqueous solution containing an admixture that is easy to mix and that prevents separation of the concrete composition material during casting in water. The present invention relates to a concrete composition for construction.
- the concrete composition of the present invention comprises a mortar composed of cement, sand and water, and a cement composed of cement, sand, coarse aggregate and water.
- the reed is to be applied underwater in that the setting is not delayed and the initial strength does not decrease.
- the high molecular weight compound is the same as the acrylic amide homopolymer
- the concrete is hard due to the strong cohesive action on the cement.
- a cement-based composition has a vinyl-based water-soluble polymer.
- R 1 represents a hydrogen atom or a lower alkyl group
- A is — C H 2-, one C ON H C H s —,
- R 3 or hydrogen atom or lower alkyl group is "5". ) Or 1 O ", n represents an integer of 0 or 1, and M represents a hydrogen atom, an alkali metal, or an ammonium.]
- R 4 represents a hydrogen atom or a lower alkyl group
- B represents one C CNH 2
- R 5 represents a lower alkyl group or a lower hydroxyalkyl group
- a concrete composition comprising 0.1 to 4% by weight of a cement of a water-soluble polymer having a constitution containing a vinyl unit represented by the following formula: Did not improve the conventional problems, but found that they had favorable characteristics.
- the present invention is characterized in that the present invention has a property that it does not separate in water, and that it can be easily mixed and kneaded without causing a setting delay and a decrease in strength.
- the vinyl monomer having a sulfonate group represented by the general formula [I] for example, 2-acrylamide ethanesulfonate, 2-acyl Liliamidrononsulfonic acid, 2—Acrylamide 2—Methylpropanesulfonic acid, 2—Metacrylylamide sulfonic acid Sulfonic acid, 2— Methacrylamide sulfonic acid, 2 — methacrylamide 2 — methylpropane sulfonic acid, acrylamide Sulfonate, methacrylamide, methansulfonate, vinylsulfonate, styrenesulfonate, or alkali metal salts thereof And ammonium salts are removed.
- the vinyl monomer represented by the general formula [E ⁇ ] includes, for example, acrylamide, metaacrylamide, N, N-dimethylacrylamide.
- N—ethylmethacrylamide, N—propylmethacrylamide, methyl acrylate, ethyl acrylate, hydroxy acrylate Shetyl, methyl methacrylate, ethyl methacrylate and hydroxyethyl methacrylate are given.
- the production of the vinyl-based water-soluble polymer compound used in the present invention may be carried out by polymerizing the vinyl-based monomer represented by the general formula [I] by a conventional method.
- the polymerization is carried out by polymerizing the vinyl monomer represented by the formula [I] and the vinyl monomer represented by the general formula [E] by a conventional method. Suitable
- OMPI This is carried out in an aqueous medium using a radical polymerization initiator such as a peroxide or an organic azo compound.
- a radical polymerization initiator such as a peroxide or an organic azo compound.
- the molecular weight of the polymer varies depending on the type and amount of the polymerization initiator used.
- the vinyl-based water-soluble polymer compound may contain a carboxyl group in some cases. It is desirable to work at low temperature.
- the present invention relates to: It is easy to knead the concrete composition briquettes, but when the copolymerization ratio is remarkably high, the properties and pressure of the concrete compositions that do not separate in water are high. It is not preferable because the compressive strength tends to decrease. Therefore, the molar ratio of the acrylic monomer represented by the general formula [T] used in the polymerization reaction is 3% or more, preferably 3 to 95%. It is.
- the molecular weight of the vinyl-based water-soluble polymer compound used in the present invention is a high molecular weight in order to give the concrete composition a property that does not separate in water. There is no particular problem if it is used, but it is preferably "100,000 or more.
- the amount of the additive is 0.1% by weight based on the cement composition. % Or more, and if it exceeds about 4% by weight, it may not only be uneconomical, but it will also be a difficult-to-handle viscous material and its compressive strength will decrease.
- a vinyl-based aqueous solution is used.
- the pre-dissolved raw concrete can be used regardless of whether it is added to the cement or added to the raw concrete. Add it to the bottle.
- a concrete dispersant for example, a condensate of melamine sulfonate phormarin, naphthalene sulfonate condensate and resin
- a sulfonate derivative such as guanine sulfonate
- a 1-axis forced kneading mixer with a capacity of 50 JZ was blended with 1% by weight of a cryl-based water-soluble polymer compound based on the cement in the concrete shown in Table 1. The state of the mixture after mixing was observed, and the kneaded concrete was subjected to a drop test in water and a compressive strength test.
- the concrete specimen was filled in a truncated cone with a diameter of 5 era at the bottom, 7 cm at the top, and 8 cm in depth, and this was previously filled to a depth of 16 cm. Place a water-filled cylindrical container 20 cm in diameter and 26 cm in depth from a position 10 cm above the water surface. Then, the water turbidity at this time was measured for transmittance at a wavelength of 6601 ⁇ by a photoelectric photometer. The lower the transmittance, the smaller the amount of cement in the concrete that has escaped into the water, and the lower the quality of the concrete. Means
- the kneading condition of the concrete was indicated in three stages. A: Within 2 minutes after the start of kneading, a uniform state with fluidity is obtained, the required slump value is obtained, and the kneading state is good.
- the vinyl-based water-soluble polymer compound having a molecular weight of about 700,000 shown in Example 1 was blended in an amount of 1% by weight with respect to the cement in the mortar shown in Table 5 to give a capacity of 34.
- the state of the mortar mixed with the mortar mixer was observed, and the kneaded mortar was subjected to a flow test, a water drop test and a compressive strength test.
- a mortar specimen was filled in a cylindrical container with a diameter of 5 cm and a length of 5 cm and filled with water 1
- the water was allowed to fall naturally from the surface of the cylinder at a height of 10 cm, and the turbidity of the water was measured at a wavelength of 660 m ⁇ using a photometer.
- the mixing state of the mortar is shown in the same way as the indication in Example ⁇ .
