Anti-dry shrinkage cement stabilized macadam base material for roads
The invention provides an anti-dry shrinkage cement stabilized macadam base material for roads, which is characterized by comprising the following components in parts by weight: cement, fly ash, calcium sulphoaluminate, a water reducing agent, a cross-linking agent, a powder defoaming agent and plant fiber foam. According to the technical scheme, the plant fibers are added, the plant fibers are reused, energy is saved, meanwhile, the performance of the cement-based material can be improved, the plant fibers are treated through the surface modifier, the interface cohesiveness between the fibers and a cement matrix is improved, the fibers and the cement matrix are bonded together, the possibility of interface fracture is reduced, and the anti-cracking performance of the cement-based material is enhanced. The plant fibers have an anti-cracking effect, so that the building material can better resist shrinkage cracking in the initial stage of construction and dynamic cracking in the later stage of construction. The powder defoaming agent can reduce pores generated by bubbles in the coating, and the water reducing agent can reduce the use amount of stirring water, so that the pores generated by water volatilization in the film forming process are reduced, and the compactness of the coating is improved.
本发明提供了一种道路用抗干缩的水泥稳定碎石基层材料，其特征在于,所述材料按重量份计包括：水泥、粉煤灰、硫铝酸钙、减水剂、交联剂、粉末消泡剂、植物纤维泡沫。通过本发明的技术方案，添加植物纤维，使植物纤维再次利用节约能源，同时能提高水泥基材料性能，植物纤维经过表面改性剂处理，提高纤维与水泥基体间的界面黏结性，使其粘合在一起，减少了界面断裂的可能性，增强了其抗裂性能。植物纤维起的抗裂作用，可以使本发明更好的抵御施工初期的收缩开裂和后期的动态开裂。粉末消泡剂可减少涂层中的因气泡而产生的孔隙，减水剂可减少搅拌水的用量，从而减水成膜过程中水份挥分而产生的孔隙，提高涂层的致密度。
