Moisture-control anti-freezing material for roadbed in plateau alpine region and preparation and construction thereof
The invention belongs to the field of building materials, and provides a humidity-control anti-freezing material for roadbeds in plateau alpine regions and preparation and construction of the humidity-control anti-freezing material. The anti-freezing component is prepared from the following raw materials in parts by weight: 21.8 parts of acrylic acid, 15.3 to 23.5 parts of a betaine type zwitterionic compound, 10.2 to 20.1 parts of chitosan, 54.3 to 60 parts of a metal salt solution with the mass concentration of 25 to 30 percent, 54.3 to 60 parts of alcohol, 1.1188 to 4.3632 parts of a cross-linking agent and 0.0864 part of an initiator. According to the improvement method, the freeze-thaw cycle resistance of the roadbed soil can be further improved, the freezing temperature of the roadbed soil is reduced, the moisture in the roadbed is intelligently regulated and controlled, the service toughness of the roadbed is effectively improved, and the improvement method provided by the invention is obvious and stable in frost heaving and thaw collapse resistance improvement of the roadbed, low in cost and environment-friendly.
本发明属于建筑材料领域，提供了用于高原高寒地区路基的控湿抗冻材料及其制备与施工，由抗冻组分和固废凝胶材料拌合而成，所述抗冻组分由如下重量份的原料组成：丙烯酸21.8份、甜菜碱型两性离子化合物15.3份‑23.5份、壳聚糖10.2份‑20.1份、质量浓度为25%‑30%的金属盐溶液54.3份‑60份，醇54.3份‑60份、交联剂1.1188份‑4.3632份、引发剂0.0864份。本发明能够进一步提升路基土抵抗冻融循环的能力，降低路基土的冻结温度，智能调控路基内的水分，并有效提升路基的服役韧性，采用本发明提供的改良方法，路基抗冻胀融沉改良明显且稳定，成本低且环保。
