what are common methods of curing the concrete structures?

Curing Methods

In concrete structures there are basic methods used to increase strength of strucures, curing is the most factor structure design, construction engineer should follow to ensure concrete reach the desired compressive strength.

1- Continuous or frequent applications of water to the surface

· Ponding: it used mainly in horizontal surfaces by applying by pond of water

· Continuous Spraying of water by sprinklers or any, avoiding alternate wetting and dryingand the application of cold water to warm concrete surfaces;

· Covering the surface with a damp absorbent material like canvas fabric or any, usually adding water to canvas two or three times per day.

2- Covering the surface to prevent water losses

· covering the surface with an impermeable material such as polyethylene, which should be well sealed and fastened

· spraying the surface with an efficient curing membrane

· applying chemical compound to the surface.

Curing Period

Curing shall continue to a period not less than 7 days, so concrete can reach 70% of its compressive strength.

Differences between development length, anchorage length and splice length

1-Development length Ld It is the minimum length of a reinforcing bar that must be embedded or "developed" in concrete to ensure that the bar can achieve its full strength in tension or compression. 2-Anchorage length La The distance that the reinforcement extends from the point where the bars are no longer required to resist moments 3-Splice length LS The distance require to transfer the force from bar to another one to upload full presentation please download this https://drive.google.com/file/d/1layyDvTlJOLzo3jfoW4K5O5UEkgoEzgN/view?usp=sharing

KEYSTONE RETAINING WALL

Introduction:- Keystone is a mechanical stabilized earth wall MSEW which used to retain soil from one side, it's less cost than concrete walls. Material 1-Keystone Blocks 2-Fiberglass Pins 3-Geo-grids 4- Back-filling Material 5-Concrete pad Different type of Geogrid: TT045 can carry load till 45KN/m. TT060 can carry load till. 60KN/m. TT090 can carry load till 90KN/m. TT120 can carry load till 120KN/m. TT160 can carry load till. 160KN/m. Method Statement 1) Place HDPE Geogrids on top of the compacted soil. HDPE Geogrids are installed from the front on top of the fiber glass pins (which penetrates the grid) and from to back, Geogrids are fixed horizontally using a steel bars. 2) Lay down the precast concrete units on top of a PC foundation at a level that is a Minimum of 5% from the wall height and reach 10% (buried height) to prevent any lateral movement . 3) Put the layers of Geotextile. 4) Backfilling using fine gravel b...
