Tóm tắt
Việc nghiên cứu tái sử dụng phụ phẩm công nghiệp để sản xuất vật liệu xây dựng thân thiện với môi trường rất được quan tâm bởi nhiều nhà nghiên cứu trên thế giới. Nghiên cứu đánh giá các ảnh hưởng của hàm lượng tro bay (FA) dùng như một phụ gia khoáng thay thế xi măng đến các tính chất kỹ thuật của hồ xi măng. FA được sử dụng thay thế xi măng poóc lăng từ 0 – 80% theo khối lượng. Kết quả cho thấy, tăng hàm lượng FA làm cho hỗn hợp có khả năng chảy tốt hơn nhưng thời gian đông kết lâu hơn. Tuy nhiên, các mẫu chứa nhiều FA hơn có cường độ chịu nén thấp hơn và độ hút nước cao hơn. Việc thêm FA làm giảm đáng kể độ co khô của hồ xi măng. Ở 28 ngày, các mẫu chứa 80% FA có giá trị cường độ chịu nén, độ hút nước và độ thay đổi chiều dài bằng khoảng 45,2%, 136,8% và 55,7% so với các giá trị tương ứng của mẫu không có FA. Do đó, tùy vào mục đích ứng dụng cụ thể mà chọn hàm lượng FA hợp lý.
