・温度下にあることから、黴の繁殖が著しい。BACKGROUND OF THE INVENTION It is well known that Japan is generally in a hot and humid environment and is provided with conditions in which mold is likely to occur. And now that air conditioners have become popular, it is said that the interiors of buildings are in perfect condition for breeding mold. In particular, humidification and heating are carried out even in the dry season, which makes it extremely convenient for the reproduction of mold. In addition, since the bathroom and other areas are under appropriate humidity and temperature, the reproduction of mold is remarkable.

いる。For this reason, the reproduction of mold on the surfaces of the inner walls and outer walls of buildings and structures, tile joints and wall surfaces in bathrooms has become a serious problem. It should be noted that the reproduction of mold is not only a problem in terms of aesthetics, but also a serious problem in that it suffers from allergic diseases. Therefore, a fungicide such as a chlorine type is used to remove the propagated fungus.

The above-mentioned object of the present invention is achieved by a fungicide-resistant cement-based material characterized by containing a fungicide in the cement-based material.

うになるからである。The antifungal agent has, for example, a Blaine value of 3000.
It is preferable to use a mixture obtained by removing the solvent from a mixture of the mineral-based fine powder of cm 2 / g or more, the antifungal agent and the solvent, for example, an organic solvent, and adsorbing the antifungal agent to the mineral-based fine powder. Here, rather than simply adding a mildew-proofing agent, it was decided to use the one in which the mildew-proofing agent was adsorbed to the mineral-based fine powder in advance. The reason is that the ability to hold is increased and it is difficult for the fungus to flow out to the outside, so that the mold can be effectively prevented from propagating from the inside (pores) of the cement-based material. In addition, even if a fungicide is mixed with cement, aggregate, water, etc., and the mixture is kneaded, the fungicide floats in water and is separated, so that it can be uniformly dispersed in the cement-based material. This is because it was difficult to make it, and rather than simply adding the mildew-proofing agent, if this is made into a powder form, uniform dispersion will be performed.

料が得られる。As the fine mineral powder having a Blaine value of 3000 cm 2 / g or more, for example, limestone, diatomaceous earth, activated clay, blast furnace slag, etc. which can be used as a cement material can be appropriately selected. Then, the antifungal agent adsorbed (adhered) to mineral fine powder such as limestone is mixed with the mortar and concrete compounding materials, and water is added and kneaded to maintain the antibacterial activity for a long time. In addition, a cement-based material that is preferable in terms of appearance and hygiene can be obtained.

Also, after the construction, there is a possibility that it may be separated and unevenly distributed together with water, and that its effect may be reduced under the highly alkaline condition of cement hydration. Various types of antifungal agents are used. For example, saltylalanide, bis (tributyltin oxide), mercury phenyloleate, copper naphthenate, zinc naphthenate, mercury naphthenate, pentachlorophenol, trichlorophenol, p-dinitrophenol, sorbic acid, butyl p-oxybenzoate, Dihydroacetate, 2- (4-thiazolyl) -1Hbenzimidazole, other benzimidazole derivatives, 1

It is preferably 4% by weight. The antifungal cement-based material configured as described above is an antifungal cement mortar or concrete at the time of construction, and it is not necessary to take antifungal measures for a building or a structure for a long period of time, a joint or an inner wall of a bathroom, It can also be applied to a wide range of applications such as outer walls.

及びＡＳＴＭ Ｇ２１「黴抵抗性試験」に従って実施し
たので、その結果を下記の表−４〜表−６に示す。The mortar thus obtained was subjected to a mildew proof test, and after curing in water for 28 days, the humidity was changed to RH.
Neutralization was promoted at 60% and carbon dioxide concentration of 10% by volume.
Then, in order to confirm the antifungal effect, JIS Z2911
And ASTM G21 “mold resistance test”, the results are shown in Tables 4 to 6 below.
