WebbDon’t seal the concrete first or apply curing compounds, which could prevent the retarder from doing its job. Apply surface retarder evenly over the surface using a low-pressure sprayer or roller. Many surface retarders are designed to form a film over the surface that acts as temporary curing agent and protects the concrete from light rain and wind. http://cpenz.integrasell.nz/userfiles/Product_Attachments/Slow_Willie_SDS_CPENZ_2024.pdf phoebe olivia

WebbDavid makes several excellent points. Concrete and 'Tufa are very different and the "wicking" effect of sugar below the surface could easily be catastrophic. I also agree with the "strong core" concept for something like this as it circumvents the problem of weakening anything below the surface altogether. Good catch, Dave! WebbUsing our Slow Willie concrete retarder, concrete pumpers can create a 3-hour delay for every yard of concrete they pour. It’s a great addition to any toolbox – plus, it’s easy to use. We also have a full line of concrete pumping support products that can help eliminate concrete build up and make the clean-up process simple.

Webb22 sep. 2024 · Sugar is used as a retarder for a concrete mix. The setting time of concrete increases with increase in the percentage of sugar up to 0.06% by weight of cement. Beyond 0.06% use of sugar it is found that the both initial and final setting times drastically reduces. Sugar when used in correct proportion acts as retarder. http://concretepumping.com/topic/slow-willie

Webb21 juli 2024 · This results in slowing set and in lower early strength gain. With proper quality production practices, long-term strengths should still be equivalent or higher than the same concrete made without a retarder. Most set retarders will also act as a water reducer. Hydration stabilizers WebbEvaporation retardants are a relatively new tool to properly cure concrete. Evaporation retardants are NOT substitutes for curing compounds! Their purpose is to prevent surface water evaporation until the curing compound can be applied. Evaporation retardants are composed essentially of water, with a mono-molecular film to slow evaporation.
