の面からも材料費全体とじて安価なものとなる。In the present invention, granulated blast furnace slag is mainly used and a binder is added to it, but the major difference from the prior art is that granulated blast furnace slag is used as a binder in granulated granulated blast furnace slag, which is pulverized to a plain value of 3000 aJ/g or more. The purpose is to use powder, and by using a large amount of this pulverized fine powder as the main binder, the strength is improved. Furthermore, by using granulated granulated powder, in addition to the above-mentioned improvement in strength, a small amount of binder is required, and conversely, the proportion of granulated blast furnace slag can be increased, resulting in lower material costs. Water permeability is further improved. By reducing the proportion of the binder, the amount of relatively expensive secondary binders such as cement and slaked lime can also be reduced, and from this point of view as well, the overall material cost can be reduced.

１表の通りである。In the present invention, granulated blast furnace slag is used as the main material. This granulated blast furnace slag is normally obtained from general granulated slag production equipment in steel works, and its composition is approximately 30 to 30% CaO.

。Figure 4 shows the change in compressive strength when cement is used as the secondary binder (C) and air-cooled blast furnace slag (A2) is used in combination with granulated blast furnace slag (^1). /
If (A++Az) is less than 10%, the strength increasing effect is small (and if it exceeds 50%, the strength is sufficient, but the specific gravity of the air-cooled blast furnace slag is large, and the mortar composition is affected by the presence of granulated blast furnace slag. This goes against the purpose of weight reduction.

It has a latent hydraulic property that reacts with gos to form hydrates and solidify, but this reaction takes a long time, whereas granulated blast furnace slag has a strong latent hydraulic property because it is glassy. has. This strong latent hydraulic property is manifested when eluted components such as CaO in the granulated blast furnace slag are eluted early to form hydrates when subjected to alkaline stimulation due to the addition of an alkaline substance such as CaO. Therefore, a binder consisting of some alkaline material is required for early consolidation.

あって、材料費が嵩む。In this case, although the above-mentioned prior art proposes a combination of granulated blast furnace slag and an alkaline substance such as slaked lime, it is not recommended to use a particle size of 0.06 mm to 0.1 u as the alkaline substance. Required. However, in reality, pulverizing or classifying into fine particle sizes not only requires a large amount of man-hours and management, but also requires 20 to 40% of the binder to 100% of the blast furnace water slag (in total) 17 to 29%), and a large amount of cement is added to this mixture at a ratio of 1:1 (example), so since such alkaline substances and cement are not cheap, the material Expenses increase.

に十分なものとなる。In contrast, in the present invention, the amount of binder is small, and the binder is mainly made of pulverized granulated blast furnace slag, which is inexpensive, has hydraulic properties, and is not easily affected by organic matter (B). ), and the secondary binder (C) such as an alkaline substance is kept in a trace amount. Since the granulated fine powder (B) can be obtained or produced at low cost and is used as the main material of the binder, the overall material cost is extremely low and the strength is sufficient.

る。ブレーン値が小さいと、強度が十分に発揮しない。The granulated fine powder constituting the main binder (B) in the present invention has a Blaine value (a value calculated by measuring the speed of air passing through a potato specimen at a constant density and amount and converting it into a specific surface area). 3000aJ/g or more is used. If the Blaine value is small, sufficient strength will not be exhibited.

: (10-30), as shown in Figure 1,
The strength can be improved by increasing the amount of total binder (A+B), but even if the amount is used in a proportion exceeding 30%, excessive strength will only be obtained, and such a high proportion will increase the material cost. It only increases. Moreover, if it is less than 10%, the desired strength cannot be obtained.

If it is added in an amount exceeding 0%, the material cost increases due to the use of a large amount of secondary binder.

等を防止できる上で望ましい。The dry mortar composition of the present invention can be blended with a small amount of water. That is, as shown in FIG. 3, the material exhibits high compressive strength when the amount of water (unit amount of water) in the entire material is in the range of 100 to 00 kg/rrr, preferably 190 to 270 kg#. It is desirable to be able to reduce the amount of water in this manner because it reduces the fluidity of the dry mortar and prevents sagging when sprayed onto a steep slope.

り対する抵抗モーメントを増大させる。Figure 5 shows an example of dry mortar DM being poured into the bed of a river with sheet piles fixed, and Figure 6 shows an example of dry mortar DM being sprayed onto a slope. In the former example, dry mortar prevents deformation of the sheet piles relative to the shoals, increases resistance to sliding in soft ground, protects riverbeds, and provides permeability. In the latter example, dry mortar absorbs the falling energy of raindrops, also prevents soil particle disturbance and slope, and also increases the moment of resistance of the slope to sliding.
