The effects of adding WTS on the properties of both fresh and hardened CLSM are evaluated using workability, setting time, drop ball time, unit weight, compressive strength, and toxicity characteristic leaching procedure (TCLP) tests.
Workability, setting time, compressive strength, flexural strength, and tensile splitting strength tests were conducted.
Also, results concluded both B/S and Si/Al ratios had a significant effect on workability, setting time and strength.
Some properties of the modified composites as heat of hydration, workability, setting time, mechanical strength, water absorption and durability were reviewed.
A series of experiments were carried out to measure workability, setting time, compressive strength, splitting tensile strength, flexural strength and dynamic elastic modulus of AAFS concrete.
Then, workability, setting time, bleeding, rheological properties, slump loss, segregation resistance and early age cracking potential and finishability are addressed among the fresh concrete properties.
The optimal mixtures of AAFS concrete were set as slag content of 20 30%, AL/B ratio of 0.4, 10 M of SH, and SS/SH ratio of 1.5 2.5 considering the performance criteria of workability, setting time and compressive strength.
Workability, setting time, mechanical properties and failure mode of PVA fibres in the mixture were studied by slump test, Vicat needle test, flexural and compression tests, and Scanning Electron Microscopy (SEM) imaging, respectively.
The results show that fly ash based geopolymer concrete for curing in ambient condition can be proportioned for desirable workability, setting time, and compressive strength using ground granulated blast-furnace slag (GGBFS) as a small part of the binder.
