Studfinders... Fuck. Them. I am 32, worked in many different construction scenarios from low digit home repairs to commercial sized high 6 figure jobs, finish work, drop ceilings in high earthquake zones, wall coverings, epoxy/poured urethane floor coverings/finished concrete/hardwoods [ncaa standards]. I have leveled concrete floors that have ...
When you purchase concrete screws, the correct size drill bit is often included in the pack. Otherwise, get a 5/32-inch bit for concrete screws that are 3/16-inch in diameter and a 3/16-inch bit for ¼-inch screws. Be sure to keep spare bits in the correct size on hand as working in masonry can wear out a bit quicker and result in improperly ...
Discussed below are a few methods of repair of concrete floors that could be used according to the necessity of the concrete floors. Sealers and Coatings Concrete sealing and coating compounds are applied to cured, dry concrete as a maintenance and repair procedure to reduce or prevent penetration of water, aggressive solutions, or gaseous media.
The grinding machine is composed of the air spindle, a high-damping resin concrete bed, and a three-axis CNC controller with high resolution AC servo motors. For the stiffness calculations of the grinding machine, a new modeling method for linear motion guides and ball screws using the three dimensional finite-element method was introduced.

Preparing a Sidewalk for Grinding. First, the grinding surface should be cleaned of all moss, dirt, and other debris. If the concrete is moldy or stained with car grease, it's worth giving it a once-over with a degreaser or concrete cleaner. If you want to grind a concrete floor that has cracked or buckled, measure the depth of the bend.

2. This answer is not useful. Show activity on this post. Most anchors don't come out of concrete. You have two choices. If you need to keep the look (little chipping) hit it with an angle grinder plus diamond blade. If you are putting something over these, hammer and sharp chisel works really fast. Share.

A method for cutting a chamfer on an edge of a concrete slab, the method comprising the steps of: making a generally planar cut, beginning a distance from the edge, with a generally circular, generally laminar concrete saw blade rotatably powered by a right-angle grinder motor, the generally planar cut being made at a desired angle and creating a cantilevered ledge above the generally planar ...
The LDT anchor is a high performance concrete anchor that cuts its own threads into concrete. The anchor bodies are made of hardened carbon steel, plated with zinc for corrosion resistance. The anchors have a finished hex washer head with anti-rotation serrations to prevent anchor back-out.
2.1.2 Pan Mixers . All pan mixers work on basically the same principle []: a cylindrical pan (fixed or rotating) contains the concrete to be mixed, while one or two sets of blades rotate inside the pan to mix the materials and a blade scrapes the wall of the pan.The shapes of the blades and the axes of rotation vary. Figure 4 shows the different combinations of blade configurations and pan.

Concrete and masonry fasteners consist of a mixture of bolts, sleeves, screws, and other components designed to set permanently in concrete, brick, and other hard materials. Sometimes, this secure fit is provided by components that expand as the bolt is drilled or threaded into the concrete.
The role of concrete anchor bolts consists of creating a permanent or, at the very least, semi-permanent bond between the structure and concrete component. Therefore, don't be too hard on the anchor bolt when it refuses to budge; it's just doing its job. The more thorough the installation job, the harder it will be to dislodge the anchor bolt from its position.
Designed for securing your nominal 6x6 posts to a concrete slab or footing, the ABA series provides the a solid connection at an excellent value. Features: A slotted hole for the concrete anchor allows for adjustment so you can achieve the perfect post alignment. The ABA66Z provides a 1" standoff to get your 6x6 post 1" off the ground.

risks associated with construction work, including concrete cutting and drilling. Certain concrete cutting and drilling may involve high-risk construction work, so a safe work method statement must be prepared and followed (see Section 2.2). All risk controls must be reviewed regularly and be adapted to take account of any changes at the workplace.
