Abstract: In recent years,with the rapid development of infrastructure in our country, concrete is one of the most important engineering materials in the construction of modern civil engineering facilities, the market has increasingly higher requirements on its workability, durability, constructability. At present, there are some problems in the practical application of concrete, such as, durability problems caused by cracking of concrete included the corrosion of steel bars and decrease in structural strength and bearing capacity, the slump loss problems of concretes, and excessive cement hydration. Therefore, researchers are committed to researching concrete admixtures with control-release effects to solve various problems. The emergence of control-release technology hasattracted great attention. It was first applied to agriculture in the 1 950 s, then applied to the research of medical drugs, and the gradually applied to the fields of fertilizers, pesticides and chemical industries. In the field of concrete, control-release technology has been applied in the performance control of cement-based materials such as internal curing, crack self-repairing, expansion process control, rust inhibition and hydration process control. Controlled-release materials that have been successfully applied in the field of concrete include SAP, microcapsules, and controlled-release polycarboxylate superplasticizer,etc. SAP absorbs a large amount of water during the cement mixing process through its complex molecular structure, and slowly releases water in time during the later hardening and drying process, so as to achieve the effect of inhibiting the deformation and cracking of cement-based materials. The microcapsule stores the repair agent in the form of composite material, so that it can be released under the external forces such as cracks, so as to inhibit the expansion of cracks and repair the cracks. In the research field of concrete slump, the continuous release of dispersant molecules in cement environment is realized by the technology of alkali-responsive slow-release, so that the fluidity of concrete can be kept stable for a long time. According to the types and characteristics of controlled-release technology, the applications and progress of controlled-release technology in concretes are respectively reviewed from physical and chemical controlled-release technology in this paper. The applications of concrete controlled-release technology in the performance control of cement-based materials such as internal curing, crack self-repairing, rust resistance, and slump retention are introduced. This article is expected to provide a reference for the research of controlled-release material with better perfor-mance in the field of concrete.
