Limestone powder modified grinding aid as well as preparation method and application thereof
The invention provides a limestone powder modified grinding aid as well as a preparation method and application thereof, and the limestone powder modified grinding aid comprises the following components in parts by weight: 1-15 parts of polyol, 0.1-5 parts of an emulsifier, 1-15 parts of silicate, 3-20 parts of organic salt, 0.1-6 parts of sodium alkoxide and 1-30 parts of an alcohol amine compound. According to the limestone powder modified grinding aid disclosed by the invention, the components are compounded according to specific contents, so that the grinding effect of the limestone powder can be greatly improved, and the hydration activity of the limestone powder can also be improved. When the limestone powder modified by the grinding aid is applied to concrete, the use amount of a cementing material can be effectively reduced, the workability of the concrete is improved, the cracking performance of the concrete is greatly reduced, and the strength of the concrete is high.
本发明提供了一种石灰石粉改性助磨剂及其制备方法和应用，以重量份计，所述石灰石粉改性助磨剂包括多元醇1～15份、乳化剂0.1～5份、硅酸盐1～15份、有机盐3～20份、醇钠0.1～6份和醇胺类化合物1～30份。本发明中，所述石灰石粉改性助磨剂通过各组分以特定含量复配，不仅能大幅度提高石灰石粉的研磨效果，还能提高石灰石粉的水化活性。将经过本发明助磨剂改性过后的石灰石粉应用于混凝土，能有效降低胶凝材料用量，提高混凝土和易性，并且混凝土的开裂性能大幅度降低，强度高。
