What can I add to cement to make it flexible?
Other fibers such as silica fibers, glass fibers, steel fibers, and asbestos fibers can be used. These micro-fibers give the new concrete its flexibility. In addition, a slick coating or anti-frictional coating is used to reduce friction between the fiber particles in the cement.
How do you mix concrete for sculpting?
- Put on a mask and protective gloves.
- Add white portland cement with binder in a 1:1 ratio in a 5-gallon bucket.

How is bendable concrete made?
The most commonly used fibers are silica fibers, asbestos fibers, glass fibers, steel fibers, etc. The flexibility property in a bendable concrete is imparted by the fibres present in it. The fibres also act as reinforcement for the concrete. This coating helps the fibers to slip over the other.
Is there a flexible Cement?
Flexible Cement is perfect for protecting saw-cut control joints in new concrete construction or repairing failed polyurea or epoxy joint fillers. Cartridge applied Flexible Cement II™ has a slower gel time than polyurea so spot repairs can be made throughout a facility with one cartridge.
How do you make homemade Shapecrete?
What recipe for a concrete mix like Shapecrete? – Quora. 1/2 part (by volume) fine sand, 1 part portland cement, 1/5 part metakaolin, 1/2 part acrylic admix. Mix dry material thoroughly, add liquid and mix like making bread dough. Knead it thoroughly.
How do you make cement soft?
The ratio is typically 1 part cement to 3 parts sand and water of course. The trick to getting a smooth final surface starts after its poured and before it sets. You will need to create or purchase a float that will be used to produce the smooth finish.
Can you make concrete without gravel?
