Airport pavement concrete for plateau regions
The invention discloses airport pavement concrete for plateau regions, which relates to the technical field of building materials and comprises the following raw materials: cement, a mineral admixture, fine aggregate, coarse aggregate, a water reducing agent, a reactive air entraining material, a bubble inhibitor and water. The reactive material is adopted, the air entraining mode of the concrete is adjusted, and the problems that gas is generated too early and is damaged by a bubble inhibitor, the air entraining effect is poor, and the durability and the crack resistance of the concrete are reduced are solved; the whole concrete can be expanded without adopting an additional expanding agent, so that the plastic shrinkage at the early stage of hydration is inhibited, and the risk of cracking of the concrete of the runway is reduced; by doping the bubble inhibitor, large bubbles clamped between the aggregate and the mortar due to stirring are eliminated in the stirring process, the compactness of the concrete is improved, and the mechanical property of the concrete is improved.
本发明公开了一种高原地区机场道面混凝土，涉及建筑材料技术领域，其原料包括：水泥、矿物掺合料、细集料、粗集料、减水剂、反应性引气材料、气泡抑制剂、水；通过采用反应性材料，调整混凝土的引气方式，避免了过早产气而被气泡抑制剂破坏，引气效果差，导致混凝土的耐久性性能和抗裂性能降低的问题；并且无需采用额外的膨胀剂就能使混凝土整体发生膨胀，抑制水化早期的塑性收缩，降低场道混凝土开裂的风险；通过掺入气泡抑制剂，在拌和过程中消除因为搅拌夹在骨料与砂浆之间的大气泡，提高混凝土的致密性，改善了混凝土的力学性能。
