Problems solved by technology

For example, when repairing airport roads and highways, due to the large traffic volume, in order to minimize the impact on traffic during repair, the road closure time should be as short as possible, which requires repair materials to reach the required strength in a short time , but the current grouting material has a long drying and hardening time, and the strength index that can be achieved in 2 hours is not satisfactory, which prolongs the operation time and cannot meet the requirements of modern high-paced operations

Abstract

The invention relates to the field of silicate cement, in particular to a self-flow hard grouting material and a using method thereof. The self-flow hard grouting material consists of cement, an expanding agent, a thickening time control agent, a retarder, a water reducer, sand, an antifoaming agent and macadam, and is characterized by comprising the following components in part by mass: 0.5 to 1.5 parts of cement, 0.05 to 0.20 part of expanding agent, 0.2 to 0.3 part of thickening time control agent, 0.004 to 0.006 part of retarder, 0.01 to 0.02 part of water reducer, 0.6 to 0.7 part of sand, 0.001 to 0.002 part of antifoaming agent and 0.7 to 1 part of macadam. The self-flow hard grouting material has the advantages of high mechanical strength and high coagulation speed.

Description

technical field [0001] The invention relates to the field of Portland cement, in particular to an self-flowing hard grouting material and a use method thereof. Background technique [0002] Grouting material is a kind of powder formulated with cement, expansion agent, water reducer, defoamer and other additives. When in use, it can be used after adding water and stirring evenly, which is very convenient. At the same time, the grouting material also has leveling properties, early strength, high strength, micro-expansion, and it has no pollution to the surrounding environment, so it is widely used in metallurgical industry, electric power industry, transportation industry and other fields. With the continuous development of the economy, various new materials are constantly emerging, and at the same time, there are higher requirements for the performance of materials. For example, when repairing airport roads and highways, due to the large traffic volume, in order to minimize...
