高分子吸水树脂（简称SAP），是一种典型的功能高分子材料。它能吸收其自身重量数百倍、甚至上千倍的水，并具有很强的保水能力，所以它又被称为超强吸水剂或高保水剂。
以自制的高分子吸水树脂(SAP)作为新型的水泥基材料自养护外加剂。
Superabsorbent polymers (SAP) were prepared and used as a novel self-curing admixture in cement-based materials.
以自制的高分子吸水树脂(SAP)作为新型的水泥基材料自养护外加剂。
Superabsorbent polymers (SAP) were prepared and used as a novel self-curing admixture in cement-based materials. SAP has good capability of absorbing and retaining water.
结果表明，施用高分子吸水树脂可提高土壤墒情、加速果实生长、提高果实产量，同时对叶片光合作用也有提高作用。
The result showed that the use of super absorbent polymers increased soil moisture, accelerated fruit growth, increased fruit yield, and improved photosynthesis of the leaves.
