Cover the concrete slab with a material such as straw or burlap that can be wetted down or with plastic sheeting that will trap the water evaporating from the concrete. The concrete should be cured over a period of time that varies from a few days to a week....

Control moisture levels in concrete by spraying water on the surface or laying wet materials on top of it Plastic sheeting orwaterproof paper laid on top of concretecan provide a protective barrier that traps moisture and allow proper curing. Blankets and heating pads can protect concrete from ha...
They proposed a design for the sliding layer with sand, cement, and polyethylene-plastic sheeting. However, the prestressed concrete pavement may be still prone to cracks if the underneath base layer is not flat [11,13]. Cement grout may be injected underneath the prestressed concrete slabs to...
covering with plastic sheeting - cheap and effective but can trap evaporated water between the slab and the sheeting spraying with a plastic membrane - relatively expensive, but becoming more popular as it produces near-ideal conditions. The membrane can be peeled off after a few days. Temperature...
This would take extra preparation such as properly sealing all sides and joints of forms and placing tarps or plastic sheeting over the freshly poured concrete to protect it from too much rain. It could also go terribly wrong at this stage, resulting in torn up concrete, lost time, poor ...
Mesh tends to keep the cracks • Preformed plastic or hard board joint strips are and joints from opening up. inserted into the concrete surface to the h. Construction joints key the two edges of the slab required depth before finishing. together either to provide transfer of loads or to ...
To minimize the risk of cracking, make sure to follow the mix instructions carefully to achieve the correct consistency. Keep your project out of direct sunlight while it’s drying, and cover it with plastic sheeting to help retain moisture during the curing process. Avoid moving or stressing ...
(0.01m2) plastic sheet to the concrete for 24 hours. Upon inspection, there should be no traces of moisture between the concrete and plastic sheeting, yet if the surface is darkened then the concrete can be considered too wet for coating. In addition, there is the moisture meter, which ...
- plastic sheeting left atop the concrete during curing combined with excessive water can cause wrinkle-pattern gray stains on the concrete surface (this is not your case as the stains are more-spotty) - leaving other materials atop the concrete during initial curing can also cause pattern stai...
