    Water-Reducing and Set-Controlling Admixtures - NPCA

    Type E – Water-reducing and accelerating admixtures Type F – Water-reducing, high-range admixtures Type G – Water-reducing, high-range and retarding admixtures Type S – Specific performance admixtures. Water reduction Each of these admixture types is defined by the range at which it decreases water.

    Water-reducing Set-controlling admixtureS

    Types A, D and E must reduce the water content by at least 5%. Types F and G are high-range water-reducers (HRWR) and are required to reduce the water content of a concrete mix by at least 12% and may in some circumstances decrease the water content of a mix by 30% or more.

    Type G: Water-reducing, high range, and retarding admixtures Note: Changes occur in the admixture industry faster than the ASTM consensus process. Shrinkage Reducing Admixtures (SRA) and Mid-Range Water Reducers (MRWD) are two areas for which no ASTM

    ACCELERATING & WATER REDUCING ADMIXTURE-CHLORIDE

    PRODUCT DESCRIPTION: Specco A-150 is a calcium chloride based, accelerating, water-reducing admixture designed to aid the placement of concrete in cold or sub-freezing temperatures. A-150 allows increased early and final strength gains formation and can be used over a wide range of temperatures by varying the dosage. A-150 can be used to

    Standard Specification for Chemical Admixtures for Concrete

    When high-range admixtures are used to impart increased workability (6 to 8-in. slump [150 to 200–mm]), the effect may be of limited duration, reverting to the original slump in 30 to 60 min depending on factors normally affecting rate of slump loss. The use of chemical admixtures to produce high-slump...

    Use of Water Reducers, Retarders, and Superplasticizer

    Superplasticizers (High Range Water reducer) Typical dosage of superplasticizers used for increasing the workability of concrete ranges from 1 to 3 liters per cubic meter of concrete where liquid superplasticizers contained about 40 % of active material. In reducing the water cement ratio, higher dosage is used,...

    High-Range Water Reducers - Euclid Chemical

    High-Range Water Reducers are used to reduce water demand at 12 - 30%. Giving the best workability, having superior slump retention and aiding in the production of High Performance Concrete (HPC) and Self Consolidating Concrete (SCC).
