  • Workability of Concrete - Tests Factors Affecting ...

    Workability of concrete is defined as the ease and homogeneity with which a freshly mixed concrete or mortar can be mixed, placed, compacted and finished. Strictly, it is the amount of useful internal work necessary to produce 100% compaction.

  • Workability, Setting Time and Strength of High

    Workability is one of the significant characteristics of high-strength concrete because such concrete is produced using a low water-cementitious ratio. Thus, extensive utilization of high range water reducer is necessary in order to attain the required rheological characteristics to facilitate mixing, transporting, placing and compacting.

  • 15 Types of Admixtures Used In Concrete -

    In addition, to increase in workability it also improves the strength of concrete, good bond between concrete and steel, prevents cracking, segregation, honeycombing, bleeding etc. Water reducing admixtures are also called as plasticizers and these are classified into three types namely plasticizers, mid-range plasticizers and superplasticizers.

  • Workability, Setting Time and Strength of High

    2.4. Workability, Workability Retention and Setting Times. High-strength concrete workability of HSCu and HSCg was assessed by applying slump test depending on the classification ASTM C143/C143M [20 ASTM, "Standard Test Method for Slump of Hydraulic-Cement Concrete", in ASTM C143/C143M ed. West Conshohocken: 100 Barr Harbor, 1998, p. 3.
