有机沥青涂层集料与无机水泥相之间的反应不相容性
Reactive Incompatibility between Organic Asphalt-Coated Aggregates and Inorganic Cement PhasesThe chemical incompatibility between aged asphalt coatings and the cement matrix, characterized by the formation of calcium–carboxylate complexes and neutralization of alkalinity, which inhibits early cement hydration and reduces mechanical strength in RAP-based concrete. / 有 aged 沥青涂层与水泥基体之间的化学不相容性，其特征是钙-羧酸盐络合物的形成和碱性的中和，这会抑制早期水泥水化并降低基于RAP的混凝土的机械强度。
