9 Steps To Repair A Crack And Injection Technique

-




Concrete cracks are repaired using different techniques and methods, such as epoxy injection depending on how wide, long and/or deep the crack is. Most of the concrete cracks are related to shrinkage, heat, wrong joint placements, over stress and loading conditions and movements caused by external factors. Some of these repairs are completed by using epoxy injections applied directly to the crack. The procedure is different and varies depending on the crack location and whether the concrete cracks are horizontal or vertical.



Crack Repair Tips 

During the process, you might notice some issues that will need your attention to complete a neat concrete injection repair process. These are some of the most common issues: 

1- Start with a low-pressure injection setting and increase the pressure as needed.



2- Larger cracks require more epoxy injection pressure.


3- When filling wide cracks, wait some time, not a lot, ensuring epoxy is filling the concrete crack. 

4- Remove the top seal using a chisel or scraper. You can also use heat gun to remove the epoxy paste.


5- Watch out for epoxy backflow as that could be a result of debris blocking the epoxy flow or perhaps the crack is not continuous.


6- If there is a leak in the top seal, use a crayon to seal the small leaking area. This is only recommended when it is a small leaking area.


7- Maintain the ports at least for 48 hours to make sure the concrete crack is sealed. 

8- When the crack is too wide, the injection method might not work. Verify before proceeding that the crack is manageable and can be fixed using the crack kit. 

9- On narrow cracks apply a bead of caulk on the side of the concrete crack at least 1/8" from the edge of the crack. at least 1/8" from the edge of the crack. This creates an area that can be used to put the epoxy minimizing the waste.

What Is The Difference Between Nominal Mix And Design Mix?

-
Image
Nominal Mix  1- When the concrete is produced by taking standard arbitrary proportions of concrete ingredients, it is known as nominal mix concrete.  2- The nominal mix is a mix considering all ratio in the volume where Strength and cost of concrete and strength of concrete varies. 3- It is Prescriptive type concrete.  4- It is used in ordinary concrete involving concrete grade not higher than M20.  5- There is no quality control. 6- Water cement ratio is based on durability criteria, experience and practical trials.  7- Water content can be modified by slump value (field-based test)  8- No entrapped air content is considered.  9. Trial mixes concept is mentioned. Design Mix  1-lt can be defined as the process of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength and durability as economically as possible. 2- Design mix is a mix considering all ratio

Types Of Pipes Used In Water Supply System/Plumbing

  Types Of Pipes:  The types of pipes commonly used in water distribution or plumbing system are described below. 1. Cast Iron Pipes:  Cast iron pipes or CI pipes are broadly utilized for distribution of water because they are less expensive, corrosion resistant, and long lasting. Cl pipes are mainly produced by following four techniques.  1. Horizontally cast (MC ware pipes)  2. Vertically cast (Pit cast in sand molds) 3. Centrifugally cast in sand lines molds spun type.  4. Centrifugally cast in water- cooled molds.  Uses of horizontally cast CI pipes are presently pretty much outdated, that's why they are infrequently produced these days. Centrifugally cast pipes are most widely used because they have more grained dense structure and uniform thickness. Generally, CI pipes are 3-6 m long, so much heavy, and require extra care to avoid from damaging while transporting and creating connections. 2. Steel Pipes:   Steel pipes are utilized in water mains circumstances where the pipes

Types Of Sand Used In Construction Works

  What Is Sand? Sand is a material obtained naturally from the locations like rivers, seas, beaches, and desserts. Sand is a granular material which consists of particles of finely divided rock. The major and the most common component of sand is silica (Si02 or Silicon dioxide), found usually in the form of quartz. Sand, consisting of tiny particles, is formed by the weathering of rocks. In this article, we will briefly discuss different types of sand used in construction.  Usually, the major source of sand is river, sea, etc. from where the sand can be obtained naturally. Other than such natural sources of sand, it can also be manufactured artificially, about which we will further learn in detail. Particles of sand are coarser than silt and finer than gravels. So, according to the Bureau of Indian Standards (BIS), earlier known as the Indian Standard Institution (ISI), the size of sand particles ranges from 0.075 mm to 4.75 mm. Based on the size of sand particles, it is further subdiv
