大模内置外保温系统专用抗裂砂浆性能研究

Study on Special Crack-resistance Mortar Properties of Internal-large-formwork Exterior Insulatin System

针对现浇混凝土模板内置保温板外保温系统有网体系做法的构造特点、技术及成本要求,研制了一种专用抗裂砂浆,并分析了集料的集配、外加剂掺加量对砂浆抗裂性能的影响。

A kind of new anti-crack mortar was introduced, which is specially based on the construction features, technology and production cost requirements of steel fabric reinforced polystyrene panel inside the concrete wall form used for exterior insulation system. Based on it, a kind of special crack-resistance mortar was developed, and the influence of material collection and the kind and amount of additive on the crack-resistance index of this new anti-crack mortar was analyzed.
