If i use a surface retarder on the surface of concrete can i then add more concrete on top and still achieve a homogeneous slab?
Yes, using a surface retarder allows for a delay in the setting of the top layer while preventing the topmost layer from bonding with the lower layer. However, to achieve a homogeneous slab, it's essential to properly prepare the surface of the cured concrete by cleaning it and possibly roughening it to ensure good mechanical interlock. Additionally, applying a bonding agent can enhance the bond between the layers and help achieve a more uniform slab.

Why must the inner surfaces of the concrete mould greased with oil?
The inner surfaces of a concrete mold are greased with oil to create a smooth release surface, preventing the concrete from sticking to the mold when it sets. This lubrication facilitates easier demolding, reducing the risk of damage to the concrete structure and the mold itself. Additionally, it helps to achieve a better surface finish on the concrete by minimizing imperfections that may arise from friction during the removal process.
Are concrete blocks cheaper then a concrete slab?
That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
How do you pour concrete on old concrete?
What you need to do first is to check if you have that room near the threshold of the door for that extra concrete(which is minimum of 3.5" inches) then you need to remove the top surface of the old concrete to be rough surface don't break too much just about an 1"wash clean and let it dry and only then to install the new concrete.
What is asphalt concrete type 1 surface course and asphalt concrete type 2 intermediate course and asphalt concrete base and tack coating between courses?
can we use polypropline fibre in concrete
How is a roller-bug used to lay concrete?
for sure it affects the surface to a certain limit as you increase the paste on the surface and decrease the aggregat amount which may lead to surface abbraision...using surface hardner will help to strenghten the surface.
Is a concrete sidewalk homogeneous?
Yes, a concrete sidewalk is considered homogeneous because it is composed of the same material throughout its structure, providing consistent properties and appearance across its surface.
How can I achieve a smooth and shiny finish when working with concrete?
To achieve a smooth and shiny finish when working with concrete, you can follow these steps: Start by properly preparing the concrete surface by cleaning it and removing any debris. Use a high-quality concrete mix with a fine aggregate to reduce the chances of surface imperfections. After pouring the concrete, level and smooth the surface with a trowel. Allow the concrete to partially set before using a steel trowel to further smooth the surface. Once the concrete is fully set, use a concrete sealer or polish to achieve a shiny finish.
How can I achieve a smooth and polished finish on concrete floors?
To achieve a smooth and polished finish on concrete floors, you can follow these steps: Start by grinding the surface of the concrete to remove any imperfections and create a smooth base. Apply a concrete densifier to strengthen the surface and reduce dusting. Polish the concrete using progressively finer grit diamond polishing pads until you achieve the desired level of shine. Seal the polished concrete with a high-quality concrete sealer to protect the surface and enhance its appearance.
Where can you buy concrete retarder to create an exposed finish in Calgary Alberta?
When we did our exposed concrete finish we used white sugar. This was a process used by our concrete finisher. He mixed it like a syrup and sprayed the forms. I used regular granulated sugar because it was a flat surface and I didn't have a sprayer... could try it on a small project first.
How can I achieve a smooth concrete finish for my project?
To achieve a smooth concrete finish for your project, make sure to properly prepare the surface by cleaning and leveling it. Use a high-quality concrete mix and follow the instructions carefully when mixing and pouring the concrete. After pouring, use a trowel to smooth out the surface, and consider using a concrete sealer to enhance the finish and protect it from damage.
How can I properly finish a concrete floor to achieve a smooth and polished surface?
To properly finish a concrete floor for a smooth and polished surface, follow these steps: Start by leveling the concrete surface with a bull float. Use a power trowel to smooth out any imperfections. Apply a concrete densifier to strengthen the surface. Polish the concrete with a series of progressively finer grit diamond polishing pads. Seal the surface with a concrete sealer to protect and enhance the finish.
How can I achieve a smooth finish on my concrete project?
To achieve a smooth finish on your concrete project, make sure to properly prepare the surface by cleaning and leveling it. Use a high-quality concrete mix and follow the manufacturer's instructions for mixing and pouring. After pouring the concrete, use a trowel to smooth and level the surface, working in small sections. Finish by using a concrete float to further smooth the surface and remove any imperfections. Allow the concrete to cure properly before applying any sealant or finish.
How can I achieve a smooth finish on concrete?
To achieve a smooth finish on concrete, you can follow these steps: Start by properly preparing the concrete surface by cleaning it and removing any debris. Use a concrete grinder or sander to smooth out any rough spots or imperfections. Apply a concrete sealer or primer to create a smooth surface for finishing. Use a trowel or float to apply a thin layer of concrete mix over the surface, smoothing it out evenly. Allow the concrete to dry and cure according to the manufacturer's instructions. Finally, sand the surface lightly to remove any imperfections and apply a final coat of sealer for a smooth finish.
What are the best techniques for using a concrete sanding block to achieve a smooth and polished finish on a concrete surface?
To achieve a smooth and polished finish on a concrete surface using a sanding block, start with a coarse grit sandpaper to remove imperfections. Gradually switch to finer grits for a smoother finish. Use circular motions and apply even pressure. Finish with a polishing pad for a shiny surface.
How can I achieve a smooth concrete floor finish?
To achieve a smooth concrete floor finish, you should properly prepare the surface by cleaning and leveling it before pouring the concrete. Use a high-quality concrete mix and ensure it is properly mixed and poured evenly. After pouring, use a bull float to level and smooth the surface, then finish with a trowel for a smooth and even finish. Finally, consider using a concrete sealer to protect and enhance the appearance of the floor.
What are the importants functions of formwork?
Formwork serves several important functions in construction, including providing support for fresh concrete, shaping the concrete to the desired form, ensuring the structural integrity of the concrete element, and helping to achieve a smooth finish on the concrete surface.
How can I achieve a smooth finish when working with concrete?
To achieve a smooth finish when working with concrete, make sure to properly mix the concrete to the right consistency, use a screed to level the surface, and finish with a trowel to smooth out any imperfections. It is also important to work quickly and efficiently to prevent the concrete from drying too quickly, which can lead to a rough finish.
