Apparatus and method for manufacturing high performance concrete capable of manufacturing high performance concrete through processes of inserting air into normal concrete and dissipating air
First Claim
1. An apparatus for manufacturing high-performance concrete by introducing air into normal concrete and dissipating air, comprising:
- a normal concrete formation unit for forming normal concrete by blending water, cement, and aggregate at a predetermined ratio;
a bubble and admixture feeding unit for feeding bubbles and an admixture to the normal concrete to increase a slump of the normal concrete;
a mixed concrete formation unit, comprising a shaft that is rotated by power of a motor in an agitator truck containing the normal concrete, and a mixing member having one or more blades radially provided to the shaft to mix the normal concrete with the bubbles and the admixture, fed from the bubble and admixture feeding unit, thus forming mixed concrete; and
a high-performance concrete shooting unit for shooting high-performance concrete of which a slump, increased due to the bubbles, is reduced to fall within a range of slump of normal concrete while dissipating the bubbles from the mixed concrete by discharging the mixed concrete using air at a high pressure of 5 atm or more.

Abstract
Disclosed is an apparatus and method for manufacturing high-performance concrete by introducing air into normal concrete and dissipating air, wherein high-performance concrete is formed in a manner in which bubbles, which are to be removed, are added in a large amount together with an admixture to pre-blended normal concrete so that the admixture is uniformly dispersed in the normal concrete using the ball-bearing effect of the bubbles, thus forming mixed concrete, and the mixed concrete is discharged using air at a high pressure of 5 atom or more to thereby shoot high-performance concrete of which the slump, remarkably increased due to the large amount of bubbles, is reduced to fall within the range of slump of normal concrete while dissipating excess air from the mixed concrete.
