What is timely cement?

Rapid cement is an increasingly used product in the world of ecological construction. Of natural origin, it only requires cooking with low heat, therefore less energy expense for its production.

Thanks to its specificities and advantages, this type of concrete is suitable for many uses, it is for this reason that seduces a lot of amateur handyman. This article explains from top to bottom as regards timely cement.

History of cements and binders

Both in China, America or Egypt, cement is used and implemented by man. The Egyptians produced Abu Rawash's pyramid using lime, sand, clay and water. The Greek of their sides perpetrated their concrete know-how while the Romans evolved it.

In addition, some cements have been described as «Roman concrete». In this case, they added pozzola or brick residues. In 1818, Baron Vicat entblast the final concrete bases with the addition of clay to the limestone. M.Vicat's first works made it possible to create the concrete that transported his name: «Ciment Vicat».

The first work of art recognized and produced with this natural binder is the famous Pont du Jardin des Piantations in Grenoble. It was built in 1855 shortly after the opening of the first modern concrete factories around 1850. This work was the modest bridge head of countless even more impressive realizations.

Ready natural cement (CNP) It is a natural hydraulic binder that is made with a single raw material. You will get it cooking between 500 ° C and 1,200 ° C of a limestone consisting of 30 %clay, extract of homogeneous benches. So you have to start a very fine grounding and let it cool. The limestone used is 100 % natural and directly from the earth.

Historically, timely cement was used for the first time in the 19th century. At that time, it was known as Roman concrete. It was used only to produce false cement printed stones. But over 1920, its diversified use. Therefore, it has become an essential product in the world of building buildings.

Currently, this type of concrete is industrially produced in France, in particular in the Grenoble region by the Vicat group. It is suitable for the French standard NF P 15-314 and has obtained European technical approval (ATE) in 2007.

What does it use for this type of cement?

Quick cement can be used for several works based on its dosage. Here are some suggestions:

• Moldings and small jobs

As part of small constructions or renovations, the use of the CNP is particularly judicious. As it was stated above, it is used to make moldings of false stones on the facades.

And today it is still used for this purpose and to restore facades or to create molds of art. It is also an interesting decoration element for some people. It will be used for small jobs such as the installation of screws or ankles.

Quick concrete is a very resistant, durable and above all waterproof mortar as it contains clay. You can use it without problems for sealing projects. It allows you to perform toilet -Sanitari, carpenter and seal the doors and windows.

• Mixtures and mortars

This natural concrete can easily act as a mortar. In fact, simply mix it with sand and water so that it becomes solid cement. In addition, it can be combined with other mortars such as hemp cement, for example.

If you add air or hydraulic lime, this product will serve as a plaster for the facade of an old building or for interiors, gobedi, joints, stones repairs, decorative craster inside, stones of stones or for gravity injections.

Other uses of quick cement

Here are other important projects that require the use of the CNP:

– Restoration of roads, tracks and highways

– Repair of the external staircase

– Maritime and Works doors

-Ne water engineering

– agriculture

– water treatment system

– construction of basins

– landscape gardeners

– Fish Farming

– etc.

The characteristics of the quick cement

This 100 % natural material has specific characteristics that make it an authentic product for construction. Here are the two peculiarities of timely cement.

• Waterproof and versatile cement

This type of concrete has excellent adhesion compared to other ranges of building materials. The CNP is perfectly suitable on a wet surface only on dry support. Membership is much higher.

Thanks to its qualities, this is the ideal element for rapid masonry work or for projects carried out in uncomfortable conditions such as humidity, cold or even immersion.

This hydraulic binder is an ecological construction material. In fact, it is cooked at a temperature lower than that of normal cement. This low temperature designates less energy consumption.

Very versatile, it is compatible with hemp fiber, lime to prepare mortars, hemp cement and with blocks of hemp fiber to isolate walls, floors and roofs.

• Taking very interesting time

The quick drying time of the cement is ultra fast unlike the conventional cement. This period is controlled by the composition, the dosage of correct concrete production without forgetting the amount of water used during the mixture.

Therefore, this product is ideal for emergency repairs as it allows rapid removal of the cassform when it is paid in position. In addition, floors and bases are reusable shortly after payment.

Here is a table showing the evolution of the resistance of the CNP in time:

The start of the socket begins about 2 minutes and ends at 4 minutes. However, you can pay this period from 3 to 15 minutes using an adherent. In general, this product is offered by the manufacturer. Don't worry, the evolution of inducement does not change.

The advantages of timely cement

The rapid cement is a highly appreciated material not only for its very fast grip, but also for its greater resistance in the face of bad weather. But these advantages are not there. Follow the details below.

The qualities of timely cement

This natural cement that appeared during the 19th^And Century has several qualities, that is to say:

– Grab almost all existing surfaces. Only, they must be moistened in advance so as not to absorb mortar water

– Resistance comes over time and guarantees its stability. It is resistant to such «aggressive» waters such as: sea water, acid water, senite water or rainwater.

– The very fast socket between 15 and 90 minutes. The hardening depends on the external temperature. In all cases, the safety of the structure is guaranteed.

– Water vapor permeability is an identical quality to the lime. In other words, let the surfaces breathe.

– Low elastic module, it is flexible enough to follow the support movements.

– Low retreat, narrows little or not once dry.

Quick concrete dosage

The dose of the CNP varies according to the work to be produced. As an indication, we present you to the dosage ready concrete in the following buildings:

– 1 volume of sand

– 1 volume of quick concrete

– 2/3 water volume

– 2 volumes of sand

– 4 volumes of Cement Prompt

– 1.5 water volume

• Moldings and small jobs

– 3 volumes of Cement Prompt

– 1 volume of water

– 2 volumes of water

– 3 volumes of Cement Prompt

The proportions of cement and sand can change according to use, but the cement/water ratio must always be 3: 1 in volume.

Preparation of quick storms

Whether it is pure or mixed, the quick cement is prepared with any mortar. Just respect the proportions indicated above or follow the indications of the concrete manufacturer.

You're very careful, The CNP dries quite quicklySo you have to prepare it at the last moment, preferably for a minimum quantity. As for the tools, you will need a depression of a bricklayer and a tank. However, you can mix this concrete manual or mechanically. It's up to you to choose.

You should only use clean sand. Mix the materials in a well clean container. Always associate your cement simultaneously with water. Never apply water after the start of the initial grip.

Know that the climate influences the time to take. So if hot, the accelerated period. On the other hand, if it's cold, the dedicated time slows down. Remember to immediately wash the tools used after each use.

Finally, put a well -appropriate protection dress for the FAI -Da -Da -before starting the job. Do not apply a quick concrete on a dirty and poorly prepared support.

The price of timely cement

The price of a quick concrete bag remains variable. Count between 6 and 9 euros to get a 5 kg bag. On the other hand, book between 16 and 20 euros to have a 25 kg bag.

This type of concrete is available in all FAI -Da -by -you stores in your region and even on the internet. Do not forget to read the recommendations recommended on the package before making the mixture. Otherwise, you risk wasting.

Advice on the use of quick cement

The rapid cement is very sensitive to the humidity that surrounds it. Absorbs it in no time. To avoid this, you have to follow these few tips:

– When mixing the materials, pay attention to excess water. In fact, the liquid slows down and alters its skills of retreat and resistance. In this case, there will be a risk of crack. Therefore, adapt the exact quantity of water mentioned on the labels and according to the humidity of the sand you use.

– Know that the quick cement must be prepared in advance and the mortar performed while the site advances. Preferably, mix a sufficient amount and not in large quantities as it has a quick grip.

– Avoid at all costs to mix concrete and sand in advance. The sand could start the action of the concrete, as it can contain a slight percentage of water. It preserves the raw material in a place far from humidity.

– The implementation of the CNP must be performed a few minutes before the start of its capture. Once you start taking, you can no longer touch it or moisten it. This can break it or modify its properties.

– Quick cement is an old 100 % natural material widely used in the field of ecological construction. In addition, as you have noticed above, it has many advantages and uses to perform all your eco -construction needs.
