That is, after pulverizing calcareous raw materials such as cement and quicklime and silicic acid materials such as silica sand, these two raw materials are mixed, water and a foaming agent of aluminum powder are mixed, and this is treated to prevent rust. It is poured into a mold set with reinforcing reinforcing bars and molded while foaming. After foaming, the material is cut into plates using piano wire before it is completely cured, and then cured with high-temperature, high-pressure steam in an autoclave to form the final product, a panel.

At the same time, in this experiment, the ratio of sulfonated melamine resin powder mixed into 100g of quicklime was varied to 0.5%, 1%, and 2%, and the digestion reaction time in each case was also investigated. saw.

Sample 5 was obtained by attaching sulfonated melamine resin powder to the surface of quicklime and passing it through a 100-mesh sieve.
The test was carried out by adding 500 cc of water (water temperature 18°C) to each sample and measuring the time it took to reach the maximum temperature (which serves as a guideline for the digestion reaction time).
この実験結果を実験例１として示す。The results of this experiment are shown as Experimental Example 1.

．． Experimental Example 2 shows the results of sequentially measuring the time taken to reach the maximum temperature for a 5% mixture, a 1% mixture, and a 2% mixture.

る。Experimental Example 2 As is clear from the results of Experimental Examples 1 and 2 above, if sulfonated melamine resin powder is mixed into quicklime and the surface of the crushed quicklime is coated, the quicklime will be digested. It can be seen that this affects the time it takes to reach the maximum temperature, and that the time required for the digestion reaction increases as the amount of sulfonated melamine resin mixed increases. In particular, in the case of tongyo quicklime, which is a special type of quicklime, the time required for the digestion reaction is extremely long compared to normal quicklime, even if the same amount of sulfonated melamine resin is mixed in. I understand. Therefore, by appropriately selecting ordinary quicklime and aged quicklime and increasing or decreasing the amount of sulfonated melamine resin mixed in, it is possible to obtain a variety of digestion reaction times, and it is possible to obtain various digestion reaction times depending on the various uses that utilize the digestive action of quicklime. This will ensure that it can be used in optimal conditions.

クリートを得るものである。First, the case where the method of the present invention is used for manufacturing cellular concrete will be explained. To produce aerated concrete, silica sand and cement are pulverized and mixed, then quicklime to which sulfonated melamine resin is attached is also mixed, and water and aluminum powder are further added and mixed. At this time, in order to form this aerated concrete into a panel shape, the mixed raw materials before foaming are poured into a formwork set with anti-rust reinforcing bars, and the foaming is performed while forming. Panel-shaped cellular concrete is obtained by cutting it into plates with piano wire and curing it in high-temperature, high-pressure steam in an autoclave.

きることになる。Next, if the method of the present invention is used as a crushing agent used in rock crushing work and concrete demolition work,
Even if it is mixed with water to form a liquid, the digestive reaction does not start immediately, so there is no need to allow time for the injection work when filling the liquid into holes drilled in objects to be crushed, such as rocks or concrete. Not only can this be done, but it can also contribute to work stability.

Since the drying agent can be adjusted to a dry state, it is possible to provide a desiccant that can withstand long-term use.

Although the crushing agent and drying agent have been explained, the present invention can be achieved by appropriately selecting ordinary quicklime and dry lime according to the intended use, and by setting the amount of sulfonated melamine resin added based on experimental data. It is possible to provide a method in which the digestion reaction time is adjusted to be optimal for the application. In other words, in the case of aerated concrete, the digestion reaction time is adjusted so that foaming does not occur during the mixing of the raw materials and that foaming occurs actively after pouring into the formwork. After mixing with water to form a liquid and injecting it into the borehole, the solution is adjusted so that the expansion pressure due to the digestive reaction gradually increases. Furthermore, desiccant agents are widely used in the fields of industrial products, food products, and even transportation and distribution, and it is possible to adjust the formulation to suit the various applications in each field and select the optimum situation speed for each application. I can do it.
本発明は前記用途に限定されず、生石灰の消化反応時間
