Concrete Power Trowel for Floor Surface

Power Trowel is widely used in surface of concrete raised paste and trowel and smooth out in high-standard workshop, warehouse, parking lot, square, airport and frame-style building.

Troweling with a steel trowel is done when a smooth, dense surface is desired, such as a warehouse or garage floor. Troweling is not recommend for external slabs in Florida, add water, a little mold, and someone wearing flip flops and you have a extremely dangerous situation.

Be sure the surface has been floated before troweling. Bull floating or darbying alone are not adequate preparation. To save time the finisher can float the slab then trowel it as he moves across the slab on knee boards.

During the first troweling use a wide trowel (at least 4 ½” wide) one that has been broken in, or a trowel that has the edges machined to give it a broken in feel. This will allow the finisher to work the trowel flat without digging into the surface.

Move the trowel across the slab in a sweeping arc motion, tilting the trowel on slightly to keep the trowel from skipping across the slab. Overlap each pass by at least half of the trowel length this will ensure that the trowel cover the surface twice.

To improve surface wear resistance, and smoothness additional troweling may be desired. On later passes use narrow trowels to increase trowel pressure at the surface.

Fresnos are large trowels that attach to bull float handles. Fresnos are used for troweling slabs that do not require a hard trowel surface. A Fresnos will speed up the troweling process. Fresnos should not be used as bull floats.

Troweling can also be accomplished by machine. Power trowels range in size from small walk-behind machines to larger double or triple rotor ride-on machine. Take care to make sure that all of the blades on a rotor are in the same condition. If one blade is bent or broken, you must change all the blades on the rotor.

SP 16 :1980 - Design Aids for Reinforced Concrete to IS:456

The structural practice handbook SP:16-1980 Design Aids for Reinforced Concrete to IS:456-1978 has tables and charts that helps structural engineers to rapidly design simple sections. Even though the design aid is based on the 1978 code, it continues to be used without revision as there have been no major changes to Section 5, on which the design aid is based.

------------- Repair and Rehabilitation of Concrete Structures --------------- By, Poonam I. Modi & Chirag N. Patel

Since the subject of repairs and rehabilitation is very exhaustive and entails great complexities / varieties in terms of types of distress / deterioration, materials and techniques available for repairs and rehabilitations, it has always been a daunting task for the authors to select aspects to be covered in this book. Following sections gives the panoramic view of this book organized into six chapters: Chapter 1 (Introduction) gives quick overview and relevance of repairs and rehabilitation of structures besides outlining general scenario of prevalence of deterioration of concrete structures, broad reasons for distress in structures explaining what can go wrong with structures, and a general roadmap and steps to be followed for carrying out any structural repairs and rehabilitation. This section also defines some of the important terms that are used in this book. Chapter 2 (Distress in Structures- Serviceability and Durability...
