| titleOfInvention |
Concrete repairing mortar and manufacturing method thereof |
| abstract |
The concrete repair mortar composition of the present invention comprises 15 to 50% by weight of a fluidized bed boiler ash; 10 to 40% by weight of cement: 2 to 6% by weight of silica fume: 2 to 6% by weight of blast furnace slag: 0.1 to 0.3% by weight of fluidizing agent; 1 to 4% by weight of an expanding agent; 0.01 to 0.15% by weight of a thickener; 10 to 50% by weight of aggregate. In order to lower the ratio of free-Cao, the fluidized-bed boiler ash is preferably coated with 0.18 to 0.22 parts by weight of water based on the ash weight, and the ratio of Free-Cao is preferably 9 to 17% based on the ash weight. When the fluidized-bed boiler ash is mixed with the concrete composition, problems such as abnormal condensation of the concrete composition, slump loss, increase of the amount of the cyclic agent, and durability are caused due to the Frer-CaO component of ash. Accordingly, the present invention reduces the amount of CaO by spraying water in a fluidized bed boiler ash, and reacting some CaO with water. As a result, the content of Free-CaO contained in ash is reduced to 9 to 17%, thereby preventing problems such as abnormal condensation and durability deterioration of the concrete composition. |
