2019/1/21· Concrete floors should be repaired with a surface topping only when the concrete slab contains surface, or hairline, cracks or has cosmetic surface flaws. If the concrete floor to be repaired is heaving, has large or wide cracks, or is damaged due to freeze damage, then other alternatives should be considered instead of resurfacing.
For slabs, concrete is left to stand until the surface moisture film disappears, then a wood or metal handfloat is used to smooth off the concrete. Floating produces a relatively even, but slightly rough, texture that has good slip resistance and is frequently used as a final finish for exterior slabs.
1 ACI Concrete Terminology A/F ratio — the molar or mass ratio of aluminum oxide (Al2O 3) to iron oxide (Fe 2O 3), as in portland cement. Abrams’ law — a rule stating that, with given concrete materials and conditions of test, the ratio of the amount of water to
Axolotl Concrete can be applied to virtually any solid surface at any size and shape and can be utilised in interior or exterior environments. Offering unlimited design possibilities, patterns and textures can be carved into the substrate then coated, or imprinted onto the surface of the concrete creating a unique juxtaposition of fine detail in what is traditionally a construction material.
Patch all cracks, crevices, and holes in the old concrete surface. For hairline cracks up to 1/8 inch wide, mix four parts of Ardex Concrete Dressing to one part water. Force the thick paste into the cracks with a putty knife. For larger cracks up to 1/2 inch wide, use
2018/3/20· Being able to “pour” the concrete is critical to getting the proper thickness of concrete in all places and to be able to smooth out the surface of the concrete. The real problem with having a large volume of water in the concrete is that to form hard concrete, the water reacts with the cement in the concrete mixture to cause high heat during the act of hydration.
