Dự đoán thuộc tính cơ học của bê tông geopolymer dựa trên metakaolin và tro bay bằng cách sử dụng SVR
Tóm tắt
Lĩnh vực vật liệu xây dựng và hạ tầng bền vững đã chứng kiến một sự chuyển mình đáng kể hướng tới các lựa chọn thân thiện với môi trường. Geopolymer, như một lớp vật liệu mới nổi, đã thu hút được sự chú ý lớn do tính chất thân thiện với môi trường và các tính chất cơ học của nó. Một trong những thành phần chính trong các công thức geopolymer là metakaolin, một vật liệu aluminosilicate được kích hoạt nhiệt, được chiết xuất từ đất sét kaolin. Bài báo này tiến hành khám phá sâu về các ứng dụng đa dạng của tro bay và metakaolin trong bê tông geopolymer, nhấn mạnh những đóng góp của nó cho ngành xây dựng, tính bền vững môi trường và các tiến bộ công nghệ. Trong cuộc điều tra này, tro bay được thay thế với các tỷ lệ khác nhau là 0%, 10%, 20%, 30% và 40% trong các nồng độ mol NaOH lần lượt là 1 M, 3 M, 5 M và 7 M. Mục tiêu là đánh giá các đặc tính cơ học của bê tông geopolymer được hình thành mới. Xem xét kịch bản nơi mà nồng độ NaOH được giữ ở 5 M. Trong trường hợp này, cường độ nén của một bê tông geopolymer (FM2), có 20% metakaolin, đã cho thấy cường độ nén tối đa là 55.28 MPa. Đáng chú ý, ảnh hưởng của metakaolin trong việc tăng cường cường độ nén dường như rõ rệt nhất khi được sử dụng làm chất thay thế ở tỷ lệ 20%.
