Choose Quality Ready Mix Concrete

If you are looking for affordable construction material, choose concrete. The production cost of the cement is comparatively low so you can buy it without exceeding your construction budget. It can also harden at ambient temperature and cast into a shape you want. It also has excellent water resistance characteristics. Though concrete has so much to offer, there are still a few builders who have not approached a concrete supplier yet. They believe that the material is prone to discolouration. Though it is not entirely wrong, visit the right concrete supplier and you don’t have to worry about discolouration.

What Is Concrete Discolouration?

For someone not aware of the term, concrete discolouration occurs when the surface of a concrete structure develops non-uniform colour. There might be mottled discolouration or deep blotches. The colour change can deteriorate the appeal of a structure so make sure you use quality concrete to make it. The colour change can also occur when cement is not mixed in the right proportion.

What Causes Discolouration Of Concrete?

It will become easier for you to deal with concrete discolouration if you are aware of the various reasons which cause it. When concrete is prepared in batches while making a structure, the source of cement or fine aggregate might change which can bring a change in placement sequence. Though this can cause concrete discolouration, it is very rare and insignificant. When you hydrate cement to a great extent, they become a bit lighter in shade. This effect can also occur due to insufficient mixing time or inconsistent use of admixtures. If you notice a greenish or yellowish tint has appeared on the concrete, it is an indication that the material contains ground slag. You can expect the shade to vanish over time. Generally, concrete discolouration does not occur due to a single factor.

Tips To Prevent Discolouration Of Concrete

Avoid using cement with high alkali content if you want to reduce the chances of discolouration.
Limit the quantity of calcium chloride or chloride-bearing chemical admixtures you are adding with concrete as it is considered to be the primary reason behind concrete discolouration.
The condition, kind or type of formwork you are using when building a concrete structure can also impact its surface colour.
Concrete suppliers in Croydon avoid trowel burning the concrete as hard trowelling the material can densify the surface and lead to dark discolouration.
Unprofessional curing of concrete can also lead to discolouration as uneven curing impacts the degree of cement hydration.

How To Minimise Discolouration Of Concrete Slab?

Since discolouration of concrete has a negative impact on the appeal of a structure, your focus should always be on minimising or preventing it. Concrete suppliers always recommend adding proper protection to prevent the concrete from drying due to sun or wind, moisten absorptive subgrades and follow the right curing procedures.

Know The Differences Between Site-Mixed And Ready Mix Concrete

Concrete is one of the most commonly used construction materials as it is durable and affordable. The production cost of cement used to make concrete is also quite low. The material hardens at room temperature and gains its strength. Fresh concrete is flowable and can be cast into any shape. You can adjust the mix and cast them into complex shapes at construction sites.

Since concrete has so many unique qualities, you can use it for a wide variety of projects without worrying about its cost. Just make sure you choose the right concrete variety which suits your construction project needs and budget. Two concrete varieties which are widely used are site-mixed concrete and ready-mix concrete. You can choose the right material for your project if you know the differences between them.

4 Differences Between Site-Mixed And Ready Mix Concrete

Preparation

The primary difference between volumetric and ready-mix concrete is the method through which the ingredients are mixed and the concrete prepared. The former is prepared at the client’s construction site by the labourers. If you want to avoid quality issues, make sure the ingredients are mixed in proper proportions. Ready mix concrete, on the other hand, is manufactured at a plant and delivered in a ready-to-use state to the construction site. Concrete suppliers sell them in volume and measure them in cubic meters.

Time Taken

Since the preparation process differs, the time taken to prepare volumetric and ready-mix concrete is also different. If you have undertaken a large size project, its speed is a vital thing to consider. Since you can load and off-load ready mix concrete easily, you can save a lot of time. Preparing site-mixed concrete is very time-consuming and there are high chances for your project to get delayed.

Equipment

The equipment used to prepare both the concrete varieties also differ. One of the equipment you will definitely need if you want to prepare volumetric concrete at the construction site is batch mixers. Whether you rent the equipment or buy one, you have to spend a few pounds. The best alternative is to approach a reputed supplier of ready mix concrete in Croydon. Since this concrete variety is delivered in a ready-to-use state to the construction site, you don’t need any equipment to prepare them.

Convenience

If convenience is your priority when working on a construction project, choose ready-mix concrete instead of site-mixed concrete. You can handle it with convenience, irrespective of the size of your project. You can also deliver it to multiple locations with ease. Volumetric concrete, on the other hand, should be mixed near the point of use to avoid any type of contamination. You also need controlled storage spaces when storing them.

Since you now know the basic differences between site-mixed and ready mix concrete, it’s time you choose one and approach a reputed concrete supplier.

How To Use Ready Mix Concrete For Your Project During Winter?

Do you have a construction project coming up this winter season? But, with the cold weather outside making things more complicated, are you perplexed about what to do? Well, even though the cold season isn’t ideal for concrete, you can turn things in your favour. Are you wondering how? Well, all you need to do is approach the best suppliers of ready mix concrete in Croydon. Trust us; they can protect your concrete from the damage of cold weather.

Pouring concrete in winter season is inevitable for contractors who have to work in colder climates. The material loses its durability, weather resistance and comprehensive strength if it freezes during the pouring and setting process. And, only the concrete suppliers and contactors protect the material from the damage of cold weather. This means that if your project requires pouring concrete during the winter months, you need to approach the experts.

The Winter Mix

As the weather gets colder, concrete suppliers will heat the material during the mixing process. The extra heat accounts for the expected drop in temperature during an average one-hour delivery in the winter season. This heat will prevent concrete from cracking, freezing and losing its comprehensive strength in the cold climate. Leading suppliers of ready mix concrete in Croydon also provide customers with the warmest possible on-site concrete.

Even the concrete mix matters to the overall project. Depending on the outside temperature and your project requirements, the suppliers will adjust the mix. This will help in pouring the concrete well and setting quickly in the winter weather.

Addition Of The Accelerators

Adding accelerators to the mix speeds up the concrete setting time as well as allow it to cure faster. Also, this prevents the concrete from freezing and experiencing any frost damage. Moreover, accelerators help in speeding up the finishing phase. The less time it takes for project completion, the better the quality of the finished product.

Water-Reducing Additives

Water-reducing additives create a higher-density paste of cement. This results in more weather-resistant and stronger qualities in the concrete.

Avoiding Fly Ash

Do you plan to expose the cement to de-icing chemicals once it cures? If so, you will want to reduce or avoid the amount of fly ash that’s added to the mix. This is because; fly ash can lead to scaling or peeling of the surface when exposed to de-icing chemicals.

Pouring Concrete In Cold Weather

Even though winter isn’t the ideal time to pour concrete, it’s possible to pour the concrete well enough. By taking just a few steps, concreting can result in a long-lasting, strong product in the cold season. To protect your poured material from damages, you need to remember certain rules. These include-

· Never pour concrete on ice, snow or frozen ground

· All protrusions and corners must be triple wrapped

· In case the ground is frozen, thaw it for two days by using blankets and heat pipes

· Cover the material until it cures completely So what are you still thinking of? Approach a reliable concrete supplier and get started with your construction project!
