研究了高吸水聚合物对混凝土的抗压强度、弹性模量和耐久性能的影响,总结了高吸水聚合物对混凝土的力学性能和耐久性能的影响规律,分析了高吸水聚合物对混凝土的影响机理. 研究表明,高吸水聚合物具有较好的吸放水特性,掺入混凝土中可影响水泥水化程度和混凝土内的孔结构,降低混凝土的抗压强度和弹性模量,但混凝土的耐久性能得到明显改善.

The effects of super absorbent polymer on the compressive strength,the elasticity modulus and the durability of concrete are studied. The influence rules of super absorbent polymer on the concrete's mechanical properties and durability have been summarized. The impact mechanism has also been analyzed as well. The study shows that the super absorbent polymer has good performance in water absorption and releasing. When mixed in the concrete it can affect the hydration degree of cement and the pore structure of concrete. The super absorbent polymer which mixed in the concrete also can reduce the compressive strength and elastic modulus of concrete. However ,the durability performance is obviously improved at the mean time .
