Cement mortar for geogrid reinforced masonry structure
The invention discloses a cement mortar for a geogrid reinforced masonry structure. The cement mortar comprises the following components in parts by mass: 0.7-1.5 parts of Portland cement; 3.8 to 5 parts of medium fine sand; 0.7 to 1 part of water; 0.08 to 0.15 part of silicon powder; and 0.06 to 0.15 part of an ultraviolet light absorber. The cement mortar is prepared from Portland cement, medium-fine sand, water, silicon powder and the ultraviolet light absorber, has the advantages of convenience in material taking and low price, has 28-day compressive strength of not less than 12MPa and 28-day tensile bonding strength of not less than 1.5 MPa, and has the characteristics of low porosity, low water thermalization, corrosion resistance and the like. After being smeared on the geogrid, thecement mortar strongly absorbs ultraviolet rays and has long-acting oxidation resistance and yellowing resistance, the possibility that the geogrid is degraded and aged due to the ultraviolet rays iseffectively reduced, the durability of the geogrid is improved, and the mechanical property of the geogrid is guaranteed.
本发明公开了一种土工格栅加固砌体结构用水泥砂浆，该水泥砂浆包括以下质量份数的组分：硅酸盐水泥0.7～1.5份；中细砂3.8～5份；水0.7～1份；硅粉0.08～0.15份；紫外线吸收剂0.06～0.15份。本发明通过硅酸盐水泥，中细砂，水，硅粉和紫外线吸收剂制备水泥砂浆，具有取材方便，价格低廉的优点，该水泥砂浆的28天抗压强度不小于12MPa，28天拉伸粘结强度不小于1.5MPa，该水泥砂浆具有低孔隙率、低水热化、耐腐蚀等特点，涂抹到土工格栅上后强烈地吸收紫外线，兼具长效抗氧、抗黄变的性能，有效降低了土工格栅因为紫外线而降解、老化的可能，提高了土工格栅的耐久性，保证了土工格栅的力学性能。
