摘　　要：针对缓凝胶粘剂的力学性能进行了系列专项研究,测试了缓凝胶粘剂固化态的抗拉强度、抗折强度以及固化过程的强度变化值,获得了缓凝胶粘剂材料的弹性模量和泊松比。通过对不同批次的试件进行测试,结果表明,缓凝胶粘剂具有优良的力学性能,具备作为缓粘结预应力技术核心介质的必需条件,从而实现与有粘结力学性能媲美的良好效应。It has been conducted a series of special studies on mechanical properties of the retard-cohesive adhesive, tested tensile strength value and flexural strength value of retarl-cohesive adhesive and intensity changing value during solidifying process, educed the modulus of elasticity and Poisson＇ s ratio of adhesive material. Through testing different batches of samples, the results indicate that the adhesive has good mechanical properties, also has the requirements as the core media for retard-bonded prestressed concrete technology, and has a mechanical effect being on a par with bonded one.
