一种活性粉末混凝土干粉料外加剂及其使用方法
摘要：
一种活性粉末混凝土干粉料外加剂及其使用方法，该外加剂的原料按重量百分比配比如下：超塑化剂粉末5%～55%；引气剂粉末2%～15%；消泡剂粉末1%～20%；粉煤灰30%～70%。本发明把无机材料与有机材料有机结合起来，通过改性解决了外加剂与无机材料及有机材料相容性的问题。活性粉末混凝土各主要性能指标既相互协调，又相互制约、相互影响。其中，通过外加剂对活性粉末混凝土的各种性能进行改性，如引气作用、减小收缩作用等，使活性粉末混凝土干粉料在加水拌合后，各组分材料产生相互叠加、相互影响效应，从而使活性粉末混凝土主要性能指标满足施工及设计要求。
摘要（英）：

The invention relates to an additive for dry reactive powder concrete powder and usage thereof. In percentage by weight, the materials of the additive are as follows: 5 to 55 percent of superplasticizer powder; 2 to 15 percent of air-entraining agent powder; 1 to 20 percent of defoamer powder; and 30 to 70 percent of coal ash. The invention organically integrates inorganic materials and organic materials together, and solves the problem of compatibility between the additive and the inorganic materials as well as the organic materials by way of modification. All the main property indexes of reactive powder concrete coordinate with, constrain and affect one another. By means of the additive, various properties of the reactive powder concrete are modified, such as the air-entraining effect and the shrinkage-reducing effect, consequently, after the dry reactive powder concrete powder is mixed with water, all the components are added to one another and affect one another, and thereby the main property indexes of the reactive powder concrete can meet the requirements of construction and designs.
