L type conctete fast repair agent consists of several kinds of inorganic compounds and high efficient water reducing agent.When the repair agent is added into the concrete,the strength of early and later periods of concrete can be improved,also the antiseep and durability of concrete can be raised.It can be used for fast repair of road surface and bridge surface concrete,and other concrete fast repair.
Main Properties of L Type Concrete Fast Repair Agent
1. Fineness:0.08mm square mesh sieve≦8.0%
2. StrengthLThe concrete strenth is according to 525#common cement weight 14% added)
3. Line Expansion Rate:
a day&0.10%
28day<0.50%

II.Method of Use and Attention Items
The concrete ration can see the following cement 1.0,sand 1.2 stone:2.8,water:0.32.
L type repair agent:0.16
2.Before repairing,the damaged concrete should be cleaned,the surface with out dust and other things,is rough,at least 20mm repairing surface should be dig out in order to avoid edge damaged concrete and ensure the adhesive strength between old and new surfaces.
3.At first,watering the repairing part by clean water,and removing the dust and slurry,and make the repairing surface wet without any water,then cast concrete.
4. Mixing work can be done by manpower or mixer,the mixed concrete should be poured into the repairing part,then leveling and ramming by vibrating machine.
5. After constructin,the wet straw bags or gunny bags should be covered on it for a day.
6. This repairing agent includes high effective reducing water agent,when mixing,It is unnecessary to add it again.
