Cement is used as basic material in cement-based Grouting Material, which is dry mixture made by cement together with appropriate natural high-strength aggregate, a variety of concrete admixtures and other components. It has high liquidity, early strength, high-strength and non-shrink characteristics after mixing with water. It is widely used in equipment foundations, steel base, secondary grouting and bolts anchoring works, as well as concrete beams, columns, plates, wall reinforcement, concrete hollow supplemental and irrigation repair, etc.
Products are divided into common type, high-strength type, early strength type, anti-freezing type, high-flow type, in which ordinary and high strength types fulfilled the JC/T986-2005 standard, the early strength and grouting agent types are fulfilled the New Zhongyan standard. Product technical indicators are as follows:

▓Good fluidity, no bleeding, it can automatically fill to the required grouting gaps;
▓It has early strength, high-strength performance. It can improve the impact resistance and vibration resistance as equipments operating. Different types can meet different requirements of projects.
▓ It has the characters of high bond strength, no shrinkage and micro-expansion that can ensure the solid combination of anchor bolts and base, as well as the old and new concrete.
▓ It has good crack resistance and impermeability, impermeability grade is higher than P20.The excellent no-shrinkage performance to ensure there is no cracks in the large area construction.
▓The type with early strength has performance of anti-corrosion. It has good performance of sulfate resistance and anti-sewage corrosion. Its erosion resistance performance can be used in harbor, sewage treatment plants and other projects.
▓UGM belongs to inorganic grouting material and it has good durability, so it is no aging, no corrosion to steel. Due to its low alkali content, it can effectively prevent harmful alkali-aggregate reaction.
▓The powder bulk density is 2100 to 2400kg / m 3 .
