Abstract

In this study, DEIPA was used for enhancing cementitious performance of bottom ash replaced cement. By applying the partial or no-known crystal structure method to X-ray diffraction data, the amounts of amorphous bottom ash and calcium silicate hydrate(C-S-H) could be separated and quantified. In the sample without DEIPA, the bottom ash hardly reacted, resulting in low compressive strength. However, the addition of DEIPA not only altered the hydration behavior of the cement but also enhanced the pozzolanic reaction between bottom ash and calcium hydroxide, leading to the generation of additional C-S-H. This resulted in high compressive strength not only in the early stages but also in the later stages. Therefore, with the addition of DEIPA during the pulverization of the bottom ash, the reactivity of the bottom ash was significantly improved. Hence, there is potential in the development of bottom ash replacement cement.

이 연구에서는 DEIPA를 사용하여 바텀애시를 미분말화하고, 이를 활용하여 바텀애시 치환 시멘트를 개발했다. partial or no-known crystal structure 방법을 X-선 회절 정량 분석에 적용하여 비결정질인 바텀애시와 C-S-H의 양을 분리하여 정량화 할 수 있었다. DEIPA를 첨가하지 않은 배합에서는 바텀애시가 거의 반응하지 않았으며, 이에 따라 압축강도도 낮게 발현되었다. 그러나 DEIPA를 첨가한 배합에서는 시멘트의 수화 거동을 변화시켰을 뿐만 아니라 바텀애시와 수산화칼슘 사이의 포졸란 반응도 향상시켜서 추가적인 C-S-H를 생성하였고, 재령 초기 뿐만 아니라 후기에도 높은 압축강도를 얻을 수 있었다. 따라서 바텀애시를 분쇄할 때 극소량의 DEIPA를 첨가하더라도 바텀애시의 반응성을 충분히 증진시킬 수 있었기에 바텀애시 치환시멘트 개발에 도움이 될 것으로 사료된다.
