Problems solved by technology

At present, the research and development of ultra-high strength and high fluidity non-shrinkage grouting materials are actively carried out at home and abroad, but there are still the following technical difficulties: 1. It is impossible to obtain a high initial fluidity, which makes construction difficult and cannot guarantee the strength after construction. Requirements; 2. Unable to guarantee the fluidity retention value in the later stage, and the construction operation time is greatly shortened; 3. It is impossible to obtain high early strength and ensure the continuous increase of later strength; 4. It cannot have corresponding good adaptability with seasonal temperature changes

Abstract

The invention discloses a grouting material which is prepared by sulphoaluminate cement, ordinary Portland cement, granulated blast-furnace slag powder, heavy calcium powder, gypsum powder, sodium aluminate, pulverized fuel ash, ceramsite, river sand, hydroxypropyl methyl cellulose, ulex europaeus agglutinin (UEA) expanding agent, naphthalene water reducer, sulphamate water reducing agent, polycarboxylic acid water reducing agent, citric acid, boric acid, sodium gluconate, sodium phosphate, sodium tartrate, calcium carbonate, lithium carbonate, calcium formate, calcium acetate, polydimethyl siloxane, polyoxyethylene polypropylene pentaerythritol ether and silicone emulsion. The grouting material has the characteristics of being rapid in coagulation time, good in flowing property, high in early strength, good in anti-fatigue performance, suitable for cold and hot weather, convenient and fast in construction, etc.

Description

technical field [0001] The invention relates to engineering materials, in particular to a non-shrinkage grouting material with ultra-high strength and high fluidity, especially a kind of grouting material used for road surface repair, hole filling, equipment and steel structure foundation grouting for emergency repair, rush construction, and rapid construction. Special engineering materials. Background technique [0002] Super early strength non-shrinkage grouting material is a kind of super high strength and high fluidity material with adjustable properties. It has the characteristics of fast setting time, good fluidity, high early strength, good fatigue resistance, not afraid of severe cold and heat, and convenient and quick construction. It can be widely used in construction with special requirements such as emergency repair and high strength. At present, the research and development of ultra-high strength and high fluidity non-shrinkage grouting materials are actively ...
