WHEN YOU NEED TO POUR CONCRETE IN COLD WEATHER

WHAT DO YOU DO WHEN YOU NEED TO POUR CONCRETE IN COLD WEATHER(τσιμεντοκονια)?

What do you do when you have to do concrete throwing in frosty weather? This is the issue that I propose

At work, natural conditions and particularly outside temperatures on chilly days are factors that

directly influence the development of protections and concrete behavior .

Since the chemical response of cement with water is an exothermic procedure, low surrounding temperatures

postpone times setting the concrete , and curing and quality development thereof. The icy weather throwing

typically permits a more noteworthy last quality of the concrete , in light of the fact that the lower the underlying temperature, the

better the hydration of the cement will be made permitting the greatest proficiency of the cementing material.

However, it will bring about development of obstruction of concrete slower and postponements in completing and

stripping tasks.

Similarly, the materials and hardware , important to

shield the concrete ought to be utilized from the principal snapshots of the placement of the concrete and along these lines

produce the important conditions for the sufficient development of protections. A standout amongst the most utilized

practices to quicken the solidifying of concrete is the placement of warmth producing lights.

Temperature conditions beneath 10 ° C can cause hindrance in the development of protections and underneath 4 °

C they start to display a summed up dormancy until said conditions change.

These circumstances legitimize the playing it safe while setting forms, curing forms and

insurance of concrete because of the impacts of frosty weather.

Great routine with regards to placement of concrete at low temperatures prompt have a fitting methodology in light of the fact that

they are basic to the toughness of concrete (additionally this behavior is an element of the thicknesses of

the components, measure of surface presented to the earth and mass of concrete ).

The concrete can be put, completed and cured in cool weather conditions, when the care designs are

adequate and the activities that add to ensure the accomplishment of putting the concrete in cool

seasons are taken. (πατητη τσιμεντοκονια)

Arranging activities

Rundown of the correct gear and work force to take impact much early.

Atmosphere insurance intend to keep up the workplace and concrete at a temperature adequate for

the placement and completing of the concrete .

Consider the utilization of specific low settlement , which lessens the season of curing and the exudation of

water , in light of the fact that the cool air hinders the dissipation rate and the time setting of the concrete .

Consider the utilization of concrete blends containing quickening added substances or the use of

high starting quality cement , which require a shorter time of insurance against solidifying.

Think about warming to the shape.

Exercises preceding exhausting concrete

On the off chance that low temperatures happen, lower than 0 ° C where there is the likelihood of ice development, this material

ought to be evacuated all together not to reach the concrete to be discharged.

Check the encompassing temperature and stickiness, if essential the base and different surfaces that come in contact

with the concrete to guarantee that they are not lower than 5 ° C.

Exercises amid the throwing of concrete

Not begin completing tasks, while emerges exudation of concrete .

Guarantee satisfactory concrete complete without overabundance water .

Utilize protection covers, warmed fenced in areas or lights to keep concrete temperatures over 20 ° C for the

initial 72 hours.

Utilize a decent quality curing compound .

Exercises resulting to the throwing of concrete

Curing and insurance of concrete

The curing is where controlled conditions are kept up in the concrete for a characterized period,

with a specific end goal to guarantee satisfactory hydration of the cement and appropriate solidifying of concrete . The cost, simplicity of

application and time are components to be considered in the decision of the curing technique for a given case.
