When wet curing is used to control the initial strength and bond of the concrete pour, it will affect the drying schedule and ultimately the overall project schedule.

  • Effect of Curing Methods on Density and Compressive

    This study considered the effect of different methods of curing on density and compressive strength of concrete. Concrete cube specimens of mix 1:2:4 were prepared with water-cement ratio of 0.65. The cubes were cured using six methods (air curing, water-submerged curing, spray curing, polythene curing, moist sand curing and

  • Rain's Effect on Fresh Concrete| Concrete Construction

    The bad news is that the surface of the concrete should not have been allowed to dry out for a week or more, a time also referred to as the curing period. The biggest problem you may be faced with is the effect the rain may have had on the surface of the concrete. If it was not covered prior to the onset of the rain, if the hardening was not

  • Properties of Concrete Workability, Setting, Bleeding

    Fresh concrete is that stage of concrete in which concrete can be moulded and it is in plastic state. This is also called "Green Concrete". Another term used to describe the state of fresh concrete is consistence, which is the ease with which concrete will flow. The transition process of changing of concrete from plastic state to hardened state.
