The invention relates to lightweight foam concrete and a preparation method thereof, and belongs to the technical field of lightweight concrete.The lightweight foam concrete is prepared from, by weight, 40-55 parts of Portland cement, 10-15 parts of petroleum asphalt, 10-20 parts of river sand, 10-15 parts of foaming agent and 8-16 parts of modified cellulose fiber; wherein the modified cellulose fiber is obtained by performing swelling treatment and steam treatment on cellulose fiber. By pressurizing the inside of the closed container during steam treatment, the processed modified cellulose fibers can also increase the compressive strength and breaking strength of the prepared lightweight foam concrete, and the use of the modified cellulose fibers greatly affects the compressive strength and breaking strength of a sample. And barium hydroxide is added into the swelling agent, so that the compressive strength of the sample can also be influenced, and the cellulose fiber with the modified breaking strength performance has relatively good anti-freezing performance in the anti-freezing aspect, and can be used in regions with relatively low temperature.
本发明涉及一种轻质泡沫混凝土及其制备方法，属于轻质混凝土技术领域，按重量份数计，其制备原料包括：40‑55份硅酸盐水泥、10‑15份石油沥青、10‑20份河砂、10‑15份发泡剂和8‑16份改性纤维素纤维；其中，所述改性纤维素纤维是由纤维素纤维经润胀处理和蒸汽处理后得到。通过在蒸汽处理时对密闭容器进行的内部进行加压，加工出来的改性纤维素纤维也可以增加制得轻质泡沫混凝土的抗压强度、抗折强度性能，使用改性纤维素纤维和对样品的抗压强度、抗折强度性能影响较大，其次在润胀剂当中加入氢氧化钡也会影响样品的抗压强度、抗折强度性能经过改性之后的纤维素纤维在抗冻方面具有较为良好的抗冻性能，可以在温度较低的地区使用。
