Cast in Place Concrete Wall

Description

Cast in place concrete wall is an exposed civil, structural system. Openings are provided in this system by generally filling with masonry, windows, or other cladding materials.

1. Cast in Place Concrete Wall: Fundamentals

Fundamentals

Cast in place wall system is a wall system that is naturally a building structure system, consist of vertical load resisting the power and lateral (seismic and wind) load resistant system. This lateral system includes a shear wall, moment-resisting frame, braced frame, etc.

In this system, the vertical load resistant system is divided into two parts, and those are horizontal framings like floor system and vertical framings like column and walls.

2. Cast in Place Concrete Wall: Performance

Performance

  • Thermal performance: Thermal resistance of this type of wall is not too good, but nowadays, some heat-resisting materials are provided to increase the thermal performance of the cast-in-place concrete wall.
  • Moisture Protection: Naturally, in the cast in place concrete joint seal is used as moisture protection is used but sometimes, for additional coating, a sealer material or concrete is used.
  • Durability: The main purpose of the cast in situ walls is for durability; it is a highly durable structure. The durability of the structure can be increased by proper water-cement ratio, minimum compressive strength, proper entrained air, etc.

Maintenance

This type of concrete maintenance work is not too much for this concrete. The maintenance process in this type of concrete requires more workmanship.

Cast in Situ Concrete Advantages and Disadvantages

Cast in Situ Concrete Advantages and Disadvantages

Advantages of Cast in Situ Concrete

There are some pros of cast in situ concrete, those are-

  1. This type of concrete easily adapts to any shape of building; that’s why it is highly preferable and widely used all over the world.
  2. Cast in situ concrete can be more or less monolithic, so the joints are only provided at the same structure.
  3. This type of concrete is naturally used for the two-way structural system.
  4. Cast in situ concrete is very adaptable for post-tensioning.
  5. In this type of concrete placing, no crane is to be needed.

Disadvantages of Cast in Situ Concrete

There are also some cons of the cast in situ concrete, those are following-

  1. In cast in situ concrete, the Formwork is very time-consuming, and it requires more manpower.
  2. Cast in situ concrete must be cured before it is subjected to any other loads.
  3. Quality control of the finished surface of this type of concrete is not assured.
  4. More manpower is required, so it is not too much an economical process.

  • It is used in building foundations. In beams, columns: cast in situ concrete is widely used.
  • The Building roof is generally made of cast place concrete.
  • Rigid pavements of roads like concrete pavements are constructed by the cast-in-place concrete.

Uses of Cast in Place Concrete

Uses of Cast in Place Concrete

  1. One of the major uses of building roofs is made of generally cast-in-place concrete.
  2. Another use of cast-in-place concrete is In beams, columns: cast in situ concrete is widely used.
  3. Cast-in-place concrete is widely used in different places like building walls, slabs.
  4. Cast in situ concrete is used in building foundations.
  5. In beams, columns: cast in situ concrete is widely used.

Concrete Casting Techniques

Concrete Casting Techniques

There are different casting techniques are

  1. At first, we prepare the concrete by batching and mixing.
  2. Then we bring the concrete from batching plant to the construction site.
  3. On the construction site, the Formwork is prepared with wood or steel.
  4. Then the concrete is placed into the Formwork, and the finishing operation is done.
  5. After 2-3 days, formworks are removed, and the concrete is ready for curing work.
  6. The curing step is done by water curing, wet curing, moisture-retaining, and liquid membrane curing.
  7. These are the techniques of concrete casting.

Specifications of Cast in Situ Concrete

  1. The availability of this concrete is very high.
  2. The compressive strength and durability of this concrete are also higher than any other concrete.
  3. It is very economical than other types of concrete.
  4. The technique of this type of concrete casting is very user-friendly.
  5. It can bear earthquake and seismic loads.

Concrete Pouring Methodology

Concrete Pouring Methodology

There are few steps of concrete pouring methodology, those are-

  1. Preparation: At first, we need to prepare the portion where it is to be prepared. Any type of obstacle is removed and produces a granular sub-base over the entire area. Then the base is compacted with some compacting types of equipment.
  2. Forming: Next, we create formworks for the concrete; these formworks may be wooden or steel. This is provided to hold the concrete. These formworks are designed for easy removal after the concrete is perfectly cured.
  3. Pouring Placement: After Formwork has been completed, concrete is placed by the concrete pump if the concrete is not able to the casting place.
  4. PR-finish: After this work, the concrete surface needs to be finished smoothly and look uniform. Then we screed the surface with trowels.
  5. Finishing: Now, the final finishing operation is done over the concrete. Various textures are applied over the concrete surface.
  6. Curing: At last, the curing process is done. It reduces the cracks in the concrete. The total curing process is running over 28 days. The different curing process is adopted for a different type of construction.
FAQ

Basement Foundation Repair

Depending on the type of issue, foundation repairs can cost as little as $500 for minor cracks and upward of $10,000 or more if the issue requires hydraulic piers. The average homeowner typically pays between $2,012 and $7,074 for foundation repair costs.

Concrete Foundation Repair

Use about 5/8 cold chisel and just knock out some of it. Making the gap wider. Now a cold chisel designed to break out in masonry. So it works fine.

Foundation Crack Repair

The good news: foundation wall cracks can often be repaired quickly and affordably. With the exception of tiny shrinkage cracks (see above), any foundation wall crack should be inspected by an experienced foundation repair contractor.

Basement Crack Repair

The good news is most basement floor cracks are normal and don’t need to be repaired. However, some cracks in the basement floor can let in water, moisture, and dangerous soil gasses (including radon).

Slab Foundation

Poured concrete block bases and slab foundations will last for a lifetime, 80 to 100 years or more, given they have been constructed with precision. The termite proofing of the base, 12 years, provided the chemical barriers remain intact. Properly installed waterproofing with bituminous coating should last 10 years.

Polymer Concrete

Polymer concrete is the composite material made by fully replacing the cement hydrate binders of conventional cement concrete with polymer binders or liquid resins, and is a kind of concrete-polymer composite.

Concrete Foundation Contractors

Foundation types vary, but likely your house or home’s addition does or will have one of these three foundations: full or daylight basement, crawlspace, or concrete slab-on-grade.

Slab Jacking

The slabjacking process, also known as mudjacking, is a method of repairing cracked and/ or sunken, broken concrete slabs without replacing the entire slab. Slabjacking is the process of lifting a building, driveway, or any object by pumping a concrete mixture beneath the item to be lifted.

Concrete Jacking

The cost of leveling, or mudjacking, a concrete surface typically ranges between $574 and $1,508, with the average being $1,041. However, it can be as low as $300 or as high as $2,200 depending on the size and condition of the area you need to level.

Concrete Polyfix

Unlike short term options like mudjacking, polylevel is a solution that will last. A study done in 2006 by argonne national laboratory found that the longevity of rigid polylevel foam is more than 1000 years.
