随着预拌砂浆的推广和普及，作为改善砂浆性能的外加剂得到了广泛的应用，不同的外加剂对砂浆的技术性能有着不同的作用。研究了四种不同砂浆外加剂对预拌砂浆技术性能的影响，结果表明，砂浆外加剂不同的掺量对砂浆的性能影响较大，当外加剂的掺量为0.025%~0.075%时，能有效提高砂浆的抗压强度和拉伸粘结强度。外加剂的掺入可以改善砂浆的收缩率和抗冻性，多组分的砂浆外加剂体现出较为优异的技术经济特性。

With the promotion and popularization of ready mixed mortar,admixture which can improve the perfor-mance of mortar has been widely used. Admixtures would affect the performance of building mortar. Here, the effect of four kinds of mortar admixture on the performance of mortars is investigated, and the results show that the admixture con-tent has a great effect on the performance of the mortar. When the admixture content is 0.025%~0.075%, the compressive strength and tensile strength of mortars increase effectively, and the shrinkage and freezing resistance are improved as well. The mortar admixture with multi-component shows more prominent technical and economic characteristics.
