BATCHING* Initial concrete from the batch plant should have a delivered slump of 2”- 4”. After addition of admixture slump should increase to 6”- 8”. Add 3 bags of admixture per yard of concrete. Do Not exceed 7 yards per truck. (In a standard 9 yard truck). Mix for 10 minutes at high speed. If additional slump gain is needed add SILATEC Liquid SP, NOT WATER!

DESCRIPTION

SILATEC FIBER REINFORCED MICROSILICA CONCRETE ADMIXTURE is a prepackaged powdered additive containing microsilica, super plasticizer, fibers and cement. Microsilica reacts chemically with the calcium hydroxide in the cement paste to produce a calcium silicate hydrate gel which yields a substantially improved in place concrete.

GENERAL USES

Designed to be used as a ready mix additive, to obtain a less permeable, more durable, longer lasting concrete. Faster strength gain from the use of this product allows coating & loading times of one or two days; whereas, regular concrete does not gain comparable strengths until cured 28 days.

BENEFITS

Prepackaged to eliminate jobsite mixing errors.
Faster strength gains.
Less down time.
Very low porosity
Better chemical resistance.
Can be coated in 24-36 hours.

APPLICATION

Add three bags SILATEC FIBER REINFORCED MICROSILICA ADMIXTURE to the following typical 5000#
PSI concrete mix design:
658# Portland cement Type I
(7 bag mix design)
1300# Sand
1800# Coarse Aggregate
250# * Water
(.35 water/cement ratio)
150# Silatec Fiber Reinforced
Microsilica Concrete Additive
(3 bags)
* CAUTION: Do not use any water reducers or super plasticizers in plant mix designs.
*An equivalent amount of ice may be substituted in hot weather to extend working time. Typical Properties of aforementioned mix design:
Compressive Strengths*
(ASTM 109)
1 day 5000 PSI
7 days 7000 PSI
28 days 9000 PSI
*Depends on water to cement ratio
Other mix designs to provide enhanced properties are available.

BATCHING
Initial concrete from the batch plant should have a delivered slump of 2”- 4”. After addition of admixture slump should increase to 6”- 8”. Add 3 bags of admixture per yard of concrete. Do Not exceed 7 yards per truck. (In a standard 9 yard truck). Mix for 10 minutes at high speed. If additional slump gain is needed add SILATEC Liquid SP, NOT WATER! Microsilica modified concrete should be handled with the same precautions of other high early strength concrete mixes.

PLACING
Place using conventional concrete placing techniques. A moisture barrier is recommended for most applications due to the quick cure times.

FINISHING
Use a fast track method of screeding, floating and finishing immediately after placing to minimize the possibility of surface cracks. Broom finish, if a coating is to be applied later.

CURING
Wet cure immediately after finishing, following appropriate concrete curing techniques. Use of a curing compound is also recommended, if a coating will be applied later, check with the coating
manufacturer for compatibility with the curing compound.

PRECAUTIONS
May cause eye, skin or lung injury.
Contains free silica. Prolonged exposure to dust may cause delayed lung disease (Silicosis). Eliminate
exposure to dust Use NIOSH approved mask for silica dust.
Contains Portland cement. If any cement or cement mixtures get into eye, flush immediately and repeatedly with water, and consult a physician promptly. Avoid contact with skin
where possible and wash exposed skin areas promptly with water. KEEP OUT OF REACH OF CHILDREN.
