Concrete Admixtures SUPER PLASTICISER Description
SAVE- IT 102 is a liquid admixture for concrete based on sulphonated naphthalene. The product may be used to effect substantial water reductions or to produce concrete with normal setting times.
Primary uses
-
Production of self-compacting concrete.
-
Pre-cast concrete.
-
Low water/cement ratio concrete.
-
In complicated formwork or with congested reinforcement.
Advantages
-
Powerful plasticising action reduces or eliminates the need for compaction.
-
Concretes of similar workability can be produced with 20-30% less water.
-
Increased compressive, tensile and flexural strength can be achieved as a benefit of its water reducing properties.
-
High early strengths can significantly increase mould utilization in precast works.
Standards
ASTM C494 Type F
IS 2645:1999
Directions for Use
SAVE- IT 102 should be added to the mix with the gauging water. No extension to the mixing time is necessary. Never add SAVE- IT 102 to dry cement. When using SAVE- IT 102 to produce flowing concrete at site using ready mix trucks, it can be added to the concrete via the feed hopper at the rear of the truck.
Dosage Rate
It is beneficial to evaluate SAVE- IT 102 by field trials, but as a general guide, to produce concrete, an addition rate of 600ml per 100kg of cement is usually sufficient to give the desired result. However, up to three times this amount may be required depending on mix design. Dosage rates will increase in low w/c ratio concrete and concrete where temperatures are high. To utilize the water reducing properties, a dosage of between 600 and 2000ml / 100kg of cement may be added.
Effects of over dosage
A severe over-dosage of SAVE- IT 102 will result in the following: Technical Data/Typical properties
Colour Dark brown/black liquid
Specific gravity 1.180-1.190 at 25° C
Chloride content Nil
pH 7 to 8
Packaging
SAVE- IT 102 is available in 10, 25, 50, 200 ltr drums.
Storage
SAVE- IT 102 must be stored in a place where temperature does not drop below +5°C. If product has frozen, thaw at +5°C and agitate until completely reconstituted. Store under cover, out of direct sunlight and protect from extremes of temperature. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging..
