A formwork of rough timber planks was utilized to create these canyon-like walls — leaving the impression of wood grain on every surface. This textured concrete finish extends across the threshold to form ceilings inside the building …
concrete. Unformed Surface: A surface that does not require formwork to provide either shape or finish to the surface, e.g. the top surface of slabs or pavements. These surfaces generally have to meet two independent tolerance criteria: the 'flatness' of the surface and variation from the designed elevation (levelness).
Vertical concrete surfaces, whether they be interior or exterior walls, columns or in any other form, need to be resurfaced periodically to maintain their structural integrity. The surface of the concrete is what prevents the elements from penetrating and destroying the interior.
With the concrete sound and contaminant-free, all that's left is to adequately roughen the surface, but to what degree? The blasted concrete surface is too rough to be measured by tape and quantified in microns or mils. The most effective reference tool for determining concrete surface profiles is the molded rubber comparator chips, available from the International …

Specifications should also say how uniform, clean, rough, and what strength the concrete substrate should be prior to a coating or overlay installation. Proposals for surface preparation specifications should clearly spell out cleaning methods, profiling method, and surface defect repair procedures.
The expanded metal is left in place (unlike timber that is removed). The resulting rough surface provides a good mechanical key and requires no further preparation. For both horizontal and vertical joints, care must be taken to ensure that the layer of fresh concrete adjacent to the joint is adequately compacted.
🕑 Reading time: 1 minute The concrete is a versatile construction material used all over the world for all types of construction applications. Concrete in its green form can be molded into any shape, size, and finish with the help of different finishing techniques and equipment to give a beautiful and long-lasting surface with a high aesthetic value.
🕑 Reading time: 1 minuteSurface preparation for the concrete repair works is the important step for the development of proper bond with the new concrete.

When selecting the grit on the sanding disc, you should look for a 24 or a 36 grit flexible disk. This will make the concrete smooth, but it will keep it rough enough so that the sealant will stick to the concrete. You will also need protective eye goggles and a face mask. Once you have your concrete sanding disc, you will need to attach it to ...
Control joints are saw cut into the surface of the concrete patio and then power washed to remove any extra release agent from the surface of the concrete before Concrete Sealer can be applied after allowed to dry. The pitfalls …

Lack of lubrication will tear up the tire and trunnion face, causing the dryer to run rough. 3. Over adjustment can result in wearing a taper in tire and trunnions.
Scoring the concrete or cutting grooves is attainable with the hammer, but for a finer surface without obvious cracking, a hand held needle scaler is optimal, with substantial man hours and skill needed to avoid over working the surace but still provide a consistent rough finish - if consistent and rough can be used together.

Saturate the surface with water, and then remove any standing water. Pour and then spread the concrete resurfacer with a long-handled squeegee. Use the squeegee to scrub the material into the surface. For a slip-resistant, …
Figure 1. Blisters are surface bumps that may range in size from 5 mm to 100 mm (1/4 in. to 4 in.) in diameter with a depth of about 3 mm (1/8 in.).

Step 4. Scoop a small amount of the slurry mix out and put it on the middle of the blade of the Mason's trowel. Apply the slurry to your new concrete wall by holding the trowel blade to the wall so the slurry is pressed onto it and wiping the slurry across the wall with a smooth arcing motion. Evenly coat a 2-by-2-foot area; this is a good size ...
Concrete Repair: Surface Prep. Surface prep. The first step was to remove the damaged concrete, using a rotary hammer to chip away the bulk of the loose material and a grinder to take the concrete down to solid material. The goal was to work back to a solid base and to fully expose the existing rebar so we could fully encase it in repair mortar.
Concrete resurfacing products are intended only for covering the surface of concrete and will serve to repair only the most superficial cracks and pits. For more substantial repairs, such as wide cracks or those that have slight …

The Jet Propulsion Laboratory is developing a class of lightweight, highly mobile, crash-proof robots for reconnaissance and security applications. Arrays of independently compliant rotary microspines are used to build wheels that enable the robots to climb stairs, mount curbs, and climb rough vertical walls. This study presents many improvements to the …
Surface finish specification. There are many concrete surface finish specifications that can be specified, for example; BS EN 13670 Execution of concrete structures – Basic, Ordinary, Plain and Special; National Structural Concrete Specification (NSCS) – Basic, Ordinary, Plain and Special. Specification for Highways Works – Class F1 to F5 ...
Step 1. Widen the crack using a chisel and hammer to a minimum of ¼ inch and break away any deteriorating concrete (the edges of the crack should be vertical or beveled in an inverted "v"). NOTE: for vertical cracks less than 1/2-inch wide and for cosmetic repairs, the best option is to use a textured acrylic caulk. Step 2.
Damages to concrete generally are repaired by filling them with a patch product. However, this won't work when the surface is vertical. Gravity will pull the patch down. To repair vertical concrete surfaces, a special product is used that starts as a liquid or paste, dries quickly and won't shift during repair.
