Optimising the Workability and Strength of Concrete ...

However, optimising concrete strength modified with high silica and alumina precursors, and crucial mix design factors are rare. Consequently, this paper optimised the concrete workability and strength, incorporating binding, water/binder ratio, binder/aggregate ratio, and curing mechanisms using the Box–Behnken design approach (BBDA).

THE WORKABILITY AND COMPRESSIVE STRENGTH OF

2017-6-29  Workability of Concrete: The workability of concrete is one of the properties of fresh concrete or mortar used to determine the homogeneity and the ease with which concrete can flow. It helps to determine the internal work required to concrete without segregation and bleeding of concrete.

2018-4-3  Workability of a fresh concrete is determined by the slump value test. Concrete strength depends on the good workability of fresh concrete. And good workability also depends on the high slump value. The main components of workability are consistency and stability. Here, stability also depends on two indexes. One is water retaining capacity which is the opposite form of bleeding and another is coarse aggregate retaining capacity which is the opposite form of segregation. Table 7 shows the slump test value of SCBA mixing concrete. Table 7. Slump test value of SCBA mixing concrete

Workability of Concrete Factors Affecting

2017-2-10  Workability is one of the physical parameters of concrete which affects the strength and durability as well as the cost of labor and appearance of the finished product. Concrete is said to be workable when it is easily placed and compacted homogeneously i.e without bleeding or Segregation. Unworkable concrete needs more work or effort to be compacted in place, also honeycombs /or pockets may also be visible in finished concrete.

2014-4-4  Workability of concrete increases with increase in water content. Higher the water content per cubic meter of concrete, the higher will be the fluidity of concrete, which is one of the important factors affecting workability. Adding more water to concrete also has some disadvantages as given below.

2018-8-20  However, a combined addition of RPF and SBR exhibited a better workable fresh mix for varying fractions. The concrete workability increased with increased dosage of RPF and SBR as shown in Fig. 9(a). This is because of the increased consistency of the mix due to the polymer microstructure of SBR latex controlling the loss of viscosity of the mix increased by the fibers.

2021-7-28  Strength of Concrete Workability Relationship. The strength of concrete is the most important property for us. It depends on density ratio or compaction and compaction depend on sufficient workability. Fresh concrete must have a workability as compaction to maximum density is possible with a reasonable amount of work.
