一、前言 R型混凝土高效减水剂的研制,是辽宁省科委的重点研究项目,该减水剂以三聚氰胺等为主要原料,经处理而形成的新型高效密胺树脂型减水剂。该产品性能大幅度超过混凝土高效减水剂国家标准(GB8076)中国标一等品的性能指标。为进一步阐述该减水剂的应用效果,本文通过与掺萘系减水剂混凝土、与基准混凝土的对比,对R型高效减水剂的应用性能作了较全面的介绍。
I. INTRODUCTION The development of R-type concrete superplasticizer is a key research project of the Liaoning Provincial Science and Technology Commission. The water-reducing agent is a new type of high-efficiency melamine resin water-reducing agent that is formed by processing melamine as the main raw material. The performance of this product has greatly exceeded the performance index of China Standard First Grade, such as the national standard for concrete superplasticizer (GB8076). In order to further expound the application effect of the water-reducing agent, the application performance of the R-type high-range water-reducer was introduced in this paper by comparison with the concrete with naphthalene-based water-reducing agent and the reference concrete.
