求翻译：(3) 乳胶粉能显著改善砂浆的施工和易性，提高砂浆的粘结强度，降低砂浆的压折比，改善抗裂性，但对砂浆的抗压强度影响不大。是什么意思？

(3) polymer powders can significantly improve the workability of mortar construction, improve the bond strength of mortar, mortar lower than the pressure off, to improve the crack resistance, but little effect on the compressive strength of mortar.

( 3) latex powder can significantly improve the mortar mortar construction and vulnerable, and raise the bond strength of mortar, lower than 10% discount for pressure resistance, improvement of the compressive strength, but the mortar will have little impact.
