摘　　要：限制膨胀率是混凝土膨胀剂的关键技术指标,介绍了一种三联式混凝土膨胀剂限制膨胀率测量装置。该装置自动对中,水中、空气中自动测量,全程无扰动,可以同条件下测量一组三个砂浆试件的限制膨胀率,降低数据离散性。同时减少劳动强度、提高工作效率,并且解决了现场无法定量检测混凝土膨胀剂限制膨胀率的难题。Restrained expansion ratio is a key technical index of expansive agent for concrete.A triple type restrained expansion ratio measuring equipment for expansive agent for concrete is introduced.This equipment is automatic centering,automatic measurement in water and air, without disturbance.It is able to determine the restrained expansion ratio of three mortar under the same conditions.Thus, it can reduce variability of date and the labor intensity, improve work efficiency.The equipment can radically solve the problem of field quantitative measurement of restrained expansion ratio of expansive agent for concrete.
