Sikacrete SCC

Self Consoldating Concrete

How-To-Use

Materials:

• Safety glasses and gloves

• Bag of Sikacrete SCC

• Sufcient water for desired mix

• Mixing container

• Mixing paddle

• Trowel or shovel (for smaller quantities)

• Drill and mortar paddle

Procedure

1. Remember to always wear waterproof gloves and safety

goggles whenever mixing or using cement-based products.

2. Start mixing with 4.2 pints of water. An additional 0.3 pint can

be added if needed. Do not over water as excess water will

cause segregation. Add Sikacrete SCC while continuing to

mix. Mix to a uniform consistency, maximum 3 minutes. Me-

chanically mix with a low-speed drill (400-600 rpm) and paddle

or in appropriate-size mortar mixer or concrete mixer.

3. Pre-wet surface to SSD(Saturated Surface Dry). Ensure good

intimate contact with the substrate is achieved. To accomplish

this, material should be scrubbed into the substrate or other

suitable means should be employed such as vibration of

the material or pumping under pressure. Vibrate form while

pouring or pumping. Pump with a variable pressure pump.

Continue pumping until a 3 to 5 psi increase in normal line

pressure is evident then STOP pumping. Form should not

deect. Vent to be capped when steady ow is evident, and

forms stripped when appropriate.

4. Within As per ACI recommendations for portland cement

concrete, curing is required. Moist cure with wet burlap and

polyethylene, a ne mist of water or a water based* compat-

ible curing compound. Curing compounds adversely affect

the adhesion of following layers of mortar, leveling mortar or

protective coatings. Moist curing should commence immedi-

ately after nishing. Protect newly applied material from direct

sunlight, wind, rain and frost.
