隆尧县超细水泥厂家

1. Introduction介绍

1.1 Description描述

Micro-fine cement is Portland cement based cements composed of ultrafine particles and are designed for injection into loose soils, rock and concrete. Because of micro-fine cement’s small particle size (the fineness largest grain size passing D95 is < 16.0 μm and Blaine value> 600 m2/kg.), it penetrates very well into tight joints, fissures and pore spaces to provide a water-tight grouted rock or soil mass. It can be used as grouting materials after adding water reducing agent (GC1).

超细水泥是经特殊设备精细研磨而成的新一代无机刚性超细材料，利用超细水泥再添加其他外加剂(例如GC1减水剂)、掺合料搅拌而成的浆液，可以用于补强加固工程的灌注作业。
