摘要：针对现浇混凝土模板内置保温板系统的构造特点、技术及成本要求，研制了一种专用抗裂砂浆。试验结果表明，不同的材料组分对该砂浆的抗裂性能都有不同的影响，通过采用不同集配的集料、不同的外加剂掺加量观察各自组分对砂浆抗裂性能的影响，并分析其影响机理。

Abstract: Crack-resistance mortar is developed for steel mesh polystyrene panel casting exterior thermal system. The test result indicated the different material component had the varying degree influence to the mortar crack resistance. Through uses the different size sand and the amount of additive, we can find there have the different influence to the mortar crack resistance.
