• 0.08 mm sieve amount: fine aggregate (3.0 % or less), crushed sand (7.0 % or less), coarse aggregate (1.0 % or less)
Mixed Material • Cement substitute used to improve performance of concrete
• Expander, fly ash, blast furnace slag powder, silica fume, anhydrous gypsum, etc.
※ Upon using concrete admixture (mixed material, admixture), the approval of the purchaser is necessary.
Admixture • The additive that improves the properties of concrete by surfactant action.
• AE agent, water reducing agent (standard type, delaying type, accelerating type), AE water reducing agent (standard type, delaying type, accelerating type)
• High performance AE water reducing agent (standard type, delaying type)

Quality

1. Strength, slump, and air volume At the point of discharge, the following conditions must be met.

  • If the purchaser specified the days, follow it. If not, it should be 28 days
  • The result of one test shall not be less than 85% of the nominal strength value specified by the purchaser.
  • The average value of the three test results shall be not less than the value of the nominal strength specified by the purchaser.

Notes on Ordering Ready Mixed Concrete

Ready Mixed Concrete Formula

Mortar

Characteristics of Mortar

  • Crack reduction performance : Manufacturing with accurate design ratio
  • Achieve superior quality : Quality control by factory production
  • Excellent work performance :Excellent pumping performance and flat performance
  • Excellent finish performance : Excellent surface finish texture and flatness
  • Excellent manageability of construction : Silo installation in a construction site is unnecessary
  • Economic Cost : Reduce material cost and construction management cost

Fiber Reinforced Concrete

Fiber Reinforced Concrete

  • Dispersing fiber in plain concrete
  • Stereoscopic reinforcement suppresses crack generation
  • Using cellulose fiber (Ultra Fiber-500)
  • Crack can be reduced by replacing wire-mesh

Fiber Reinforced Concrete

Good Finishing Performance of Concrete Surface

Natural wood fiber creates good dispersibility.
No surface exposure and no fiber-balling phenomenon

Excellent Crack reduction performance

Cost reduction and good workability,
replacing Wire-Mesh

Excellent economical efficiency and construction

Three-dimensional reinforcement on shrink tensile stress and
hydration reaction control ability from water retention of wood fiber

Various Applications

Various kinds of plain concrete
(Underground parking lot floor finish, waterproof layer pressing, etc.)
Decoration concrete, color concrete, etc.

Comparison of Characteristics of Fiber Reinforced Concrete

Category Wire-Mesh Concrete Fiber Reinforced Concrete
Size Wire-Mesh ( #8-@ 150 *150 ) Cellulose Fiber 0.30㎏/㎥
Reinforcement Type Planar reinforcement crack control ability is insufficient Three-dimensional reinforcement is sure to reduce cracks
Material Property Metal Hydrophilic wood fiber
Chemical Resistance Poor acid resistance – corrosion Good acid resistance and alkali resistance
Water Resistance Defective – corrosion phenomenon Good
Strength and Weakness • On-site transportation and installation are difficult
• Management of yard space and corrosion are necessary
• It is difficult to maintain uniform coating thickness
• Watertight can be easily torn during installation
• Crack inhibition ability is not effective
• Excellent workability (concrete factory mix)
• Reduce construction period and cost
• Excellent finish performance
• Excellent crack reduction performance

Exposure Concrete

Exposure Concrete

Exposed concrete is a construction that includes finishing work as well as frame construction.
The concrete should be good in workability, and the material separation of the aggregate, the pavement, and the cold joint should not occur.
The natural color of the concrete should be maintained or the color of the color concrete should be maintained.

Characteristics of Exposed concrete

Reduce Construction Period by Concurrent Work of Construction

Finishing process after concrete pouring is unnecessary.

A Variety of Colors

You can produce colorful concrete
by adding colors to concrete.

Skip painting work

The natural color of the concrete remains intact, pure, and natural.
The surface is smooth like being coated, so no painting is necessary.

Comprehensive Coverage

It can be applied to a variety of areas.

High Strength Concrete

Concrete with tensile strength of 40 Mpa or higher is called high-strength concrete. It is possible to secure the safety of the structure and reduce the construction cost,
because it has high durability, maintenance cost is reduced, and economical efficiency is high. Therefore, it is widely used for compression member of structures,
and also in bridges, PC beams, etc.

Low Heat Concrete

It is the concrete that minimizes the temperature, crack and stress caused by hydration heat of cement by lowering the heat of hydration of cement carcass or mixing technology of mineral admixture. It is mainly applied to super huge structures such as underground structures, dams, marine, and port structures.

User Demand Combination

Depending on the situation of the construction site, the product can be delivered at the ratio required by the contractor.
After receiving a field formulation design table, the design is applied to the product, which in turn is quickly delivered.
