Pouring concrete: pouring technology for different purposes, tips for different times of the year

Whether you’re building a patio, a driveway, or the foundation for a building, pouring concrete is an essential step in any construction project. Making the correct decision is crucial to guaranteeing the structure’s robustness and longevity. Although the procedure might appear simple, there are a few things to take into account that could have a big impact on the result.

The objective of the concrete is among the most important things to remember. Various approaches are needed for different projects, ranging from the mix ratio to the curing procedure. Comprehending these subtleties can aid in attaining optimal outcomes, regardless of the size of the construction project or the small DIY project you’re working on.

The season has a big impact on how concrete is poured. There are different obstacles to overcome when pouring in the summer heat than when working in the winter cold. By understanding how to modify your methods according to the weather, you can avoid common issues like freezing, cracking, or incorrect curing.

This post will discuss the fundamental tricks and methods for pouring concrete in different seasons and for a variety of uses. These tips will assist you in making sure that your concrete work endures over time, regardless of your level of experience.

How to prepare a surface for pouring

The first step in the technological process is surface preparation. The amount of excavation work done is determined by the type of future structure. Drainage is set up to remove moisture at the following stage. This is a two-layer backfill made of medium- or fine-grained crushed stone and sand. The layers have been tightly packed.

Formwork is erected to stop the solution from spreading. You can use any flat material. To create curved profile paths, plastic sheets are utilized. The framework is positioned at the trench’s boundaries and fastened with bars hammered into the earth. The future product’s shape is decided by the formwork.

Waterproofing is set up during the pouring preparation stage. It is essential to stop liquid from the solution escaping into the ground and moisture from the soil seeping into the concrete. Apply waterproof material, polyethylene film, or roofing material.

Next, start laying the reinforcement, which provides strength to the design. A metal grid consisting of wire that is at least 6 mm in diameter is employed. Welded cells must be at least 100 × 100 mm in size. Place on top of the sheets. They reinforce using rods that have an 8 mm cross section and are connected to one another in place of a grid.

Tools and equipment for filling

Pour concrete into structures that have been prepared by hand or with industrial concrete. In the event that a solution is ordered, a mixer—a unique piece of machinery—will deliver it.

Create a wooden groove for the mixture to be directed onto in order to pour it into the formwork. Concrete pumps are drawn to large-scale construction sites where the mixer is unable to get close to the filling.

With your own hands, a concrete mixer prepares the solution. A 1 m³ mixture requires approximately 4 hours of labor; the actual time required varies based on the specifications of the apparatus. You could easily fill a floor or foundation with such productivity.

Depending on the technology being used and the amount of construction being done, additional equipment might be required for the task. For the delivery of concrete or bady, you might require a car. A flooded solution must necessarily be free of air bubbles. A section of the reinforcement or a specialized vibrator performs this manually.

Shovels and hammers may be the remaining tools needed. If the reinforcing cage is made of rods, either set up a welding machine or store the rods with knitting wire.

How technologically correctly pour a concrete mixture

The correct technology must be chosen and followed in order to produce high-quality concrete structures.

For the sexes

They used a perforator to break off the old screed in order to lay a concrete floor in the apartment. After cleaning the surface, fill.

A private home’s floor is laid out on an earthen foundation.

• mark the floor level;
• level the soil surface, add more if necessary;
• lay waterproofing;
• insulate in a suitable way;
• reinforce if increased loads are expected;
• create formwork from beacons, dividing the area into separate sections – cards.

In a 1:2:4 ratio, combine cement, sand, and crushed stone to make concrete. Starting from the corner furthest away from the door, pour concrete. Fill the card with the solution, level it with a shovel, poke several holes in it with a rod, and extend it across the whole surface.

A vibrator is used for better compaction. Proceed to the following card once the shrinkage ceases and the cement milk reaches the surface.

Once multiple areas are occupied, begin leveling the flooring. Install a long rule on the beacons and pull it in your direction. The floor is leveled as excess mixture seeps into the empty cards. After the cards are completed, remove the beacons and use mortar to fill the spaces.

Once the work is finished, let the fill sit for four days. Every day, mist with water to avoid cracks. After that, wrap in film and let it sit for three to four weeks to allow it to fully set. Wet occasionally with water.

On the hardened surface, create a screed by using self-leveling mixture or liquid cement mortar. Let it stand for two to three days, giving it daily water sprays.

For the foundation

Pouring any kind of foundation uses the same technology. Mix or order the concrete composition after the preparatory work. Purchasing with delivery is preferable when the volume is high because it’s the only method to establish a monolithic foundation.

Two workers straighten the solution in the trench while one person holds and guides the chute if the mixer is able to pull up to the location. Starting from the corners, pour until the entire perimeter is filled.

A columnar foundation’s construction involves a few features. This is made up of pillars joined by grillage rather than a continuous strip.

Prior to reinforcing the supports, which are drilled holes 20 cm above the column’s level, the rods are released. Fill with concrete. Next, construct the grillage formwork, which joins the columns, install the reinforcement, and pour.

Underneath the whole house is a slab foundation built on a cushion of sand and gravel. Along with laying out a reinforcement frame, concrete is poured.

Into the formwork

If a mixer is used to deliver the solution, it is immediately poured over the whole area to a predetermined height. It is not always possible to prepare enough mixture to cover the entire volume of the structure when using a concrete mixer or doing manual preparation.

As a result, there are technological approaches for partially laying the foundation.

There are two choices. The formwork in the first example is layered, but not excessively so. In the second method, individual blocks are placed along the entire height of the space, creating a beveled sidewall to securely join the individual parts. If the work stoppage exceeds one day, allow the previously poured solution to dry. The seams must be cleaned with a brush and then rinsed with water prior to applying fresh concrete.

Using a vibrator or rod, air is extracted from the freshly poured mixture. Using a heavy hammer, tap the formwork to cause the concrete to settle and compact. The surface is then leveled.

Into water

There are two ways to pour concrete into water in industrial construction: pile and caisson. There are two choices available when building a private home. The caisson and the first are comparable. Combine the ingredients for the concrete, transfer it into sacks, and place them in the pit above the waterline. Before the composition hardens, the bags are left for a month. After that, set up the formwork and pour it utilizing the approved technique.

The option with capillaries is more intricate. Create a liquid solution that is fed into the pit using a cushion that has been prepared and is free of crushed stone.

The following technologies are used to complete the work:

1. Metal pipes with a cross-section of 40-100 are installed in the trench at equal distances mm. Pour a layer of crushed stone above the groundwater level.
2. A liquid cement mixture is poured into the pipes, which flows out of them and fills the space between the crushed stone. The pipes are gradually raised so that the solution is evenly distributed throughout the entire volume of the structure.

Using this method will require a crane or winch for filling. The fact that you have to regulate the process and the pipes keep rising is another challenge. A platform is constructed so that someone can direct lifts and watch as the pipe fills.

The process of pouring concrete calls for meticulous planning and attention to detail, particularly when taking the project’s goal and the time of year into account. Knowing the proper methods and equipment for the job is crucial, whether you’re installing a driveway, a decorative surface, or a foundation. The quality of your pour can be significantly impacted by seasonal factors such as temperature and humidity, so it’s important to modify your technique for summer, winter, or wet conditions to ensure a long-lasting and resilient outcome.

Molds for pouring

Paving stones, facade stones, and tiles are all made with industrial molds.

They make homemade ones out of flexible plastic for their own needs because they are too costly. The kind and thickness of the material have an impact on how long the molds last.

When big items like curbs, pillars, and piles are cast, plywood and boards are used to knock down wooden formwork. Make sure the wood is thoroughly wet with water before using. This approach is also utilized when numerous identical tiny products are required.

The mold is sometimes created underground. Concrete is poured into the pits along with heavily moistened sand. After leveling the surface, a film is applied, and water is applied until the surface is completely set.

Any material can be used to create stone or tile stencils, including kid-made dishes or molds. Use old tires that are the right size to cast a ring.

Foam plastic is best for a disposable mold. It is hollowed out and filled with concrete. The mold must be broken in order to remove the product. However, the material can be arranged in the most bizarre ways.

Pouring concrete is a task that needs to be carefully planned and executed, taking into account the time of year and the purpose of the concrete, among other things. Whether you’re pouring concrete for a driveway, foundation, or decorative element, you can guarantee a long-lasting and successful result by being aware of the particular requirements of your project.

Depending on the season, you should modify your concrete pouring techniques. While hot weather necessitates precautions to prevent rapid drying and cracking, cold weather demands actions to keep the concrete from freezing. You can attain a smooth and long-lasting finish by modifying your strategy according to the situation.

You may greatly simplify and expedite the concrete pouring process by taking the proper procedures and considering the particular needs of your project. No matter the season, you can confidently take on any concrete project with a little planning and the appropriate methods.
