〜、ポリスチレン発泡粒、カラス発泡粒等の発泡骨材が
ある。Conventionally, the aggregate for insulation concrete is 21 - C is barley i.
There are foamed aggregates such as ~, polystyrene foamed granules, and crow foamed granules.

Insulating concrete can be obtained by kneading the mixture while adding water and admixtures such as Δ[agent] as appropriate so as to obtain predetermined workability and raw specific gravity.
しかしながら上記５Ｎ泡骨材を使用して断熱二１ンクリ
ートを製造した場合法のよう−な欠点があった。However, when the above-mentioned 5N foam aggregate was used to manufacture heat-insulating concrete, there were disadvantages as described above.
（ｉ）混練り中に壊れやすいこと。(i) Easily broken during kneading.
■圧力吸水量が多く、吸水により骨材の強度が落ちるこ
と。■The amount of water absorbed under pressure is large, and the strength of the aggregate decreases due to water absorption.
■上記■の理由によりポンプ圧送による現場打設には適
さず、作業効率を低下させること。■Due to the above (■), it is not suitable for on-site pouring using pump pressure, which reduces work efficiency.
■特にガラス発泡粒の場合は、セメント中のアルカリに
よりおかされる危険があること。■Especially in the case of glass foam granules, there is a risk that they will be affected by the alkali in the cement.
■特にポリスチレン発泡粒等有機材の場合には、耐火性

・材を投入しで軽く渥練りづることにより、当該発泡骨
材の表面にペーストをイｑ＠さける。An appropriate amount of water is applied to the foamed aggregates serving as the core material by means of spraying or other means, with the amount of surface water being adjusted. Then, to the foamed aggregate whose surface water content has been adjusted in advance, a back core material of pace 1 to 1, such as cement 1-type such as G-Vt cement, thermosetting resin material such as Ceracola 1-boxy, etc., is used. Base compatible with foamed aggregate]
・By adding the material and kneading it lightly, spread the paste on the surface of the foamed aggregate.

ことが出来る。These bases 1- dry after a predetermined period of time, and as a result, a shell with a low water-cement ratio is formed on the surface of the foamed aggregate. Various combinations of the foamed aggregate and paste material are conceivable; for example, for pearlite, any thermosetting resin such as G-I-T-cement, calcined gypsum, or J-boxy can be used; Thermosetting resins are not suitable for 1-dilene foamed grains because they mix, but jet cement and calcined gypsum can be used.For glass foamed grains, jet cement and other resins can be used because they are sensitive to alkalis. Cement systems can be covered using suitable ceramics. Among the Ceracola types, calcined gypsum is particularly desirable because it is resistant to alkali and has a fast reaction rate. Even when glass foam particles are used as the core material, a cement-based paste material can be used if the material of the glass foam particles is alkali-resistant.
