How to Protect Your Home During Extreme Cold Weather

In cold weather, either the water to the washer or the drain to the sewer freezes. We have opened the wall and put more insulation, added an inside vent to allow house heat keep the area warm, placed a small electric heater behind the washer, and after every wash day add travel trailer antifreeze in the drain.

Cold Weather Concreting

Cold Weather Concreting. Cold weather slows the cement/water reaction (cement hydration process) which in turn increases the set time of freshly placed concrete. The National Ready Mixed Concrete Association (NRMCA) discusses a good rule of thumb that a 20 degree drop in concrete temperature will approximately double the concrete setting time.

What is Concrete Temperature Limit? - The Constructor

Concrete placed & cured at a moderate temperature (15–25°C) will gain higher strength & durability than 35°C concrete. Curing concrete at high temperature accelerates curing and strength achievement, but provide lower maximum concrete strength. ACI 306 specify limits for concrete temperature in cold weather conditions.

Can I Use Quick-Set Concrete in the Rain? | Hunker

Quick-set concrete is a dry concrete mix that has calcium chloride added. Calcium chloride causes the concrete to harden, or set, within 30 minutes or less of adding water to the mix. It can then take up to 4 days to cure and harden to its maximum strength.

Rain water intruding into the concrete mixture before its set can be problem for the surface finish, but not the bulk of the mixture. Concrete adheres to the subsoil components. If its wet/mushy and/or very sandy, the resistive capacity to horizontal movement is much less. A slightly wider and much deeper footing will be more resistant.

When Cold Temperatures Affect Sealers | Concrete Decor

As we transition from fall to winter, the days get shorter, the leaves fall into the concrete we are trying to finish, and the temperatures start dropping. The concrete blankets come out and cold-weather concrete practices start to take place. The changes in how concrete is placed should also trigger changes in how sealers are applied.

When can you get a grinder on new cold weather concrete

When can you get a grinder on cold weather concrete? As we are coming out of the winter, I have multiple projects where the concrete was placed during cold temperatures. Although there are ACI standards for cold weather placements, I still experience quite a few slabs that have issues related to cold weather placements.

Laying Concrete in cold and wet weather conditions | iMix

As a result, trying to lay concrete in more adverse weather conditions can pose a risk, as it has the potential to compromise the finish - both visually and structurally - of the concrete once it has dried. Two of the most challenging scenarios to be laying concrete in are cold weather and wet weather conditions.

The reality of cold weather compaction | Asphalt magazine

In terms of cold weather paving, what a contractor should be most interested in is the time they have available to achieve compaction. During cold weather, all things being equal, the asphalt mat will cool much faster than it will during warmer weather, shrinking the available compaction time.

4 Winter Maintenance Tips For Stamped Concrete

Seal It Up. Before the weather gets too chilly, give your stamped concrete a good scrub down to remove any dirt and debris and apply a sealant. Sealants will prevent the concrete from staining and can keep the worst of winter's wear and tear - think ice melts and similar products - from damaging intricate stamping.

Setting concrete Piers in cold weather - Fine Homebuilding

We do a lot of cold weather concrete in Canada, its no problem if the right precautions are taken. Mix design plays an important part. First, you can't pour on frozen ground as it will cause instability in the sub-grade similar to poor compaction. So cover the excavated areas to keep from freezing.

Controlling Cold-Weather Condensation with Insulation | BSC

Condensation within walls during cold weather is a common performance problem. Most such condensation is due to air leakage, not diffusion. Although air barrier and vapor control layers can reduce the quantity and occurrence of condensation due to both mechanisms, the use of exterior insulation (even if that insulation is a vapor barrier and/or air barrier) can warm sensitive surfaces
