It is also becoming more and more used. For example, if lightweight aerated concrete is crushed into fine pieces and spread inside all chicken houses without fcALC, the ammonia concentration t I P
It has been confirmed that the odor can be reduced to below Pm and deodorized to such an extent that it cannot be detected as a bad odor. Lightweight aerated concrete, which is used for purposes other than building materials, is also called porous lightweight calcium silicate, and is conventionally made by adding water to a mixture of silica stone or silica sand, quicklime, and aluminum powder and kneading it.

かった。<Problems to be Solved by the Invention> Porous lightweight calcium silicate is used as a treatment material for accumulated waste as described above because it has deodorizing and dehydrating effects, but it is mainly used as a deodorizing material. It is used. On the other hand, the porous lightweight calcium silicate contains a large amount of silicic acid and lime and is porous, so the present invention utilizes it as a fertilizer. What is important in this case is whether silicic acid, etc. is contained in a form that is easily absorbed by crops, but although conventional porous lightweight calcium contains a large amount of silicic acid,
It could not be said that it was contained in a form that was easily absorbed by crops.

ムとすることを特徴とするものである。<Means for Solving the Problems> The present inventor conducted various experiments to solve the above problems, and found that when porous lightweight calcium silicate is used as a fertilizer, the effect as a fertilizer is The present invention was completed by clearly assuming that the amount of silicic acid does not increase in proportion to the total amount of silicic acid, but increases in proportion to t of silicic acid that can be dissolved in 0.5N HCl (the effective amount of silicic acid, hereinafter the same). This is what led to this. That is, the purpose of the present invention is to improve the ratio of the effective amount of silicic acid to the total amount of silicic acid (referred to as effective ratio, hereinafter the same).
It is an object of the present invention to provide a method for producing porous lightweight calcium silicate that has an enhanced effect as a fertilizer by increasing its effectiveness as a fertilizer. The present invention achieves the above object in a method for producing porous lightweight calcium silicate by autoclaving a mixture of a silicate raw material, quicklime, and aluminum powder, in which activated silicic acid is used as all or a part of the silicate raw material. The present invention is characterized in that a porous lightweight calcium silicate for fertilizer is produced using quality materials such as amorphous silicic acid such as diatoms, blast furnace slag, or highly reactive silica stone.
一般に、多孔質軽量珪酸カルシウムは、珪酸石灰を多量

して著しい効果を発揮することができるのである。In general, porous lightweight calcium silicate contains a large amount of lime silicate and is porous, so it can be considered to be used as a fertilizer, but in order to obtain the effect as a fertilizer, the effective ratio is It was found that 30 or more pores are required, and in order to obtain a significant effect as a fertilizer, it is necessary to have a large number of pores and an effective ratio of 45% or more. In the conventional case where silica stone is used as the siliceous raw material, the activation rate was about 30%, whereas in the case of the present invention where activated siliceous material is used as all or part of the siliceous raw material, If the effective ratio is easily 60 to 70%, it can exhibit remarkable effects as a fertilizer.
特に多孔質であることは、珪酸カルシウムの表面積の増

を使用しないことについての不都合はない。In particular, the fact that it is porous is linked to an increase in the surface area of calcium silicate, and the solubility of silicic acid and calcium in water is thought to be one of the reasons for the high utilization rate of silicic acid by crops, which is noteworthy. (See Table 4)
. Activated siliceous material is a general term for crystalline or non-crystalline materials that contain silicic acid and exhibit high reactivity, such as amorphous silicic acid such as diatomaceous earth, blast furnace slag, or highly reactive silica stone. be. When an activated siliceous material is used in this way, the activation rate increases, and silicic acid and the like are contained in a form that is easily absorbed by crops, which, in combination with the multi-porosity property, makes it highly effective as a fertilizer. It should be noted that the method of the present invention utilizes the effective use of lime silicate contained in porous lightweight calcium silicate and its multi-porous property, and is not related to materials used as construction materials, but is used for materials that require strength. First, there are no disadvantages to not using silica.

Furthermore, it has been found that the autoclave treatment time, which has the greatest impact on the cost of the product, can be shortened in proportion to the amount of active siliceous material added to the total siliceous raw material. That is, as is clear from a comparison of Sample 1.2 using silica stone, the effective amount of silicic acid decreases when the autoclave treatment time is shortened, whereas in the present invention, for example, diatomaceous earth is
Samples 6 to 9 in which 0% of silicic acid was mixed showed almost no difference in the effective amount of silicic acid even if the autoclave treatment time was shortened.

February 19th Test Example 4 The amount of sio eluted from the porous lightweight calcium silicate according to the present invention by shaking and water temperature was tested as follows. That is, porous lightweight calcium silicate was thoroughly crushed in a mortar, the particle size was made uniform, and Sample 2 was accurately weighed.
Add 50 liters of water to this and immerse the whole container in an incupator for a predetermined period of time. During this time, I decided to shake it by hand from time to time.
