The results show that with more glass sand replacement and higher liquid-solid ratio values, the workability is better, and the slump and slump flow are higher.
The workability is considered an important factor when concrete mixtures are designed; especially in some applications where members are heavily reinforced.
As far as the workability is concerned, in fact all the concretes the control and the MK mixtures have obtained their design slumps as shown in Table 2.

The workability was analyzed.
The workability was evaluated using the flow table test.
The workability was measured by slump and mini-flow tests.
The workability was measured from the slump when the concrete was mixed manually or mechanically.
Although the mixture sets in a short period of time (less than 30 min), the workability was good and the developed fibre reinforced composite was used for a large scale application in a canoe.
The experimental results showed that the workability was gradually increased as the replacement level of natural sand by glass cullet was increased, and it was significantly improved with decreasing aggregates-to-binder ratios.
Compared to a non-optimised concrete with 100% replacement of fine aggregates with rubber, the compressive strength of concrete with optimised binder material and moderate water/binder ratio was enhanced by up to 160% and the workability was improved significantly.
In addition, when a W/B ratio of 0.25 was used, the workability was obviously deteriorated and slightly higher AE agent was required, as compared with W/B ratio of 0.275 or 0.3.
