Đóng góp của tro nông nghiệp và HDPE như một vật liệu thải để môi trường bền vững áp dụng cho việc ổn định đất sét có độ dẻo thấp
Tóm tắt
Các phương án đã được khám phá nhằm tăng cường độ cho các loại đất ở thành phố Chiclayo, Peru, đặc biệt là những loại đất có tính dẻo và độ bền thấp. Mục tiêu là nghiên cứu các thuộc tính cơ học bằng cách sử dụng tro bã mía (SCBA) và polyethylene mật độ cao (HDPE) như những phương pháp gia cường bền vững và tiết kiệm chi phí. Tro đã được nung ở bốn nhiệt độ khác nhau, và mỗi mẫu trải qua một thử nghiệm phát xạ tia X năng lượng. Mẫu có tổng oxit cao nhất đã được trộn với đất sét với tỷ lệ tăng dần, từ 5 đến 20% theo trọng lượng. Sau đó, tỷ lệ SCBA có hành vi cơ học tốt nhất đã được chọn, kết hợp với các tỷ lệ tăng dần của sợi HDPE từ 0,25 đến 1,0% theo trọng lượng. Kích thước được giữ cố định với chiều dài 25 mm và chiều rộng 15 mm. Các kỹ thuật ổn định hóa học và vật lý đã được áp dụng cho đất nghiên cứu. Đất trộn với tro có ảnh hưởng trực tiếp đến các tham số của phép thử nén và chỉ số khả năng chịu tải California (CBR) ướt, cho thấy sự gia tăng đáng kể 32,08% cho đến 10SCBA. Tuy nhiên, vượt qua tỷ lệ này, độ bền giảm xuống dưới mẫu kiểm soát. Kết quả chỉ ra rằng đất sét cải thiện hành vi và độ bền của nó với tỷ lệ 10SCBA + 0,75HDPE, dẫn đến sự gia tăng đáng kể trong CBR ướt lên tới 154%. Việc sử dụng liều lượng tối ưu của tro và sợi có ảnh hưởng đến việc tạo ra một lớp nền cho lưu lượng giao thông thấp và cao; thêm vào đó, nó giảm thiểu các vấn đề ô nhiễm bằng cách giảm lượng rác thải và các bãi chứa đô thị, góp phần vào tính bền vững của môi trường.
