して充分な性能ではなかった。However, when conventional thermosetting cement is used, it takes time to demold the formwork, resulting in poor work efficiency.
Furthermore, the long-term durability was poor, and the performance as a thermosetting cement was not sufficient.

完成するに至った。The present invention is a further improvement of the invention disclosed in JP-A-60-131953, and by mixing and pulverizing a latent hydraulic substance and a predetermined amount of an alkaline stimulant, thermosetting properties and strength after heat curing are improved. The present invention has been completed based on the knowledge that the process can be improved and economical efficiency can also be improved through the effective use of industrial by-products.

アルカリ刺激剤３重量部未満では強度発現に対する効果
はほとんどなく、２０重量部を超えると逆に強度が低下
するだけではなく、耐久性の面でも好ましくない。If the alkaline stimulant is less than 3 parts by weight, it will have almost no effect on strength development, and if it exceeds 20 parts by weight, not only will the strength decrease, but it will also be unfavorable in terms of durability.
これらは粉末状で混合粉砕後、所定量の水が添加される
。These are in powder form, and after mixing and pulverizing, a predetermined amount of water is added.

活性シリカを添加することができる。活性シリカの中で
もシリカフラワーなどの超微粉の添加が効果的である。In the present invention, activated silica can be added to improve thermosetting and durability. Among active silica, it is effective to add ultrafine powder such as silica flour.
活性シリカの添加量は潜在水硬性物質１００重量部に対

速度は遅く、又１２０℃を超える場合には熱的変形が起
きやすく、その熱硬化性セメントを使用した製品の機械
的強度が低いものとなる傾向がある。The heat curing temperature in the method for producing thermosetting cement according to the present invention is 60 to 120°C. If the temperature is less than 60°C, the curing speed is slow, and if it exceeds 120°C, thermal deformation is likely to occur, and the heat curing temperature is 60 to 120°C. Products made with synthetic cement tend to have low mechanical strength.
加熱時間は、物によって変形するので、限定はできない
が、１時間以内が好ましい。The heating time varies depending on the material, so it cannot be limited, but it is preferably within 1 hour.
