초록
압축강도 50 MPa이상의 압출성형 시멘트 패널은 고온고압 증기양생으로 생산된다. 고온고압 증기양생에서 요구 강도를 얻기 위해서는 시멘트에 포함되어 있는 CaO와의 반응에 필요한 적정량의
One of the basic physical properties of the hardened cement paste, the rigidity, is deteriorated during concrete matrix forming, depending on the replacement rate of the crushed stone powder, and due to drying shrinkage. Therefore, the concrete containing crushed stone powder has been limitedly used as non-structural construction material. To improve these disadvantages, a hydrothermal reaction employing method can be considered. High-temperature and high-pressure water is involved in the hydrothermal reaction in the mixing with specific materials. The rigidity improving mechanism is related to the synthesis of calcium silicate. The calcium silicate is produced through reaction between calcium compounds and the silicic acid. Various kinds of calcium silicate can be produced depending on the CaO/
