The product's major asset, aside form its striking architectural beauty, is its ability to remain white throughout its life. White concrete, obviously, is not a surface treatment that can deteriorate with age.
Some early generation lignosulfonate-based admixtures, however, can turn white concrete slightly yellow. Every effort should be made to maintain a constant water to cementitious materials ratio in a mix for a given project as variations in water content may result in a visible shift in concrete color.
The advantage of using a white concrete mix is that it will not fade. Painting or staining gray cement can risk chipping or fading over time. Cladding: White concrete panels, normally on the outside of a building, can be extremely striking and reflect light effectively.
b<>Hint: The cement when reacts with water, it gets hardened and set in the shape it is present. If due to rain, the cement bag has been wet, then the cement will react with water and will get hardened. This reaction is irreversible in nature and can not be reversed back.
One of the advantages of white cement is that it offers a much better surface for the beginning. At the same time, it hides the cracks formed with a durable, matte surface. Another advantage of white cement is its effect on paints, a white surface makes the paint stand out while protecting the walls from moisture.
How Long Does White Cement Take to Dry? The drying time for white cement is very similar to standard portland cement. The mix should be set in about 30 minutes, then is likely to properly set within 8 to 10 hours.
Mix one cup of bleach with one cup of powdered laundry detergent, then add 15 cups of hot water. Pour your mixture over your driveway's dirty areas, such as the parts that contain oil stains. Work your mixture in using a bristle brush and scrub for approximately 20 minutes.
Vinegar and Baking Soda
Simply fill a spray bottle with equal parts water and vinegar (or water and baking soda), and add a little bit of liquid dish detergent. Spray the mixture on your concrete surface and let it sit for about 30 minutes. Then scrub and rinse your concrete.
Pressure washing is one of the fastest, most effective ways to get your concrete white again. Concrete can change color over time due to pollen, algae, or dirt buildup, but a good pressure wash can easily remove dirt and stains and make your concrete look new again.
If you do not want to deal with the primer, you can use white cement. Through its structure, it provides you coarse finish compared with the wall putty. If you want to present quality work by spending much more time, white cement might be a better choice for you.
2. Concrete countertops scratch & stain easily. This is especially true for white concrete countertops! Cement is actually a pretty fragile surface that stains and cracks easily.
Bleach is commonly used to whiten concrete and is very effective at doing so if the initial stain is removed beforehand. Bleaching stained concrete white prepares it for any additional coloring treatments that you may wish to apply in the future.
✅ White cement has a strong waterproof effect. We need not any waterproofing coating on the structure. The structures made of White cement are able to withstand the highest temperature.
Physical characteristics of white cement are more or less similar to OPC. However, its specific surface is more and compressive strength is 90 % of that of 33-grade OPC.
What is the strength of white cement? Production of white concrete with a compressive strength between 25 and 50 Mpa is possible by using white cement. It was also found out in study that white concrete had higher compressive strength than normal gray concrete.

A quick answer is yes! White vinegar can clean concrete and remove stains. It may not be as powerful as concrete cleaners, but it can clean up concrete stains on a budget.
Concrete discoloration is not a rare event
These factors include: Variability in concrete mixtures. The use of too much or not enough water. The use of calcium chloride.
When it comes to white cement concrete, there are several factors that can lead to unwanted stains on its surface. Whether it's grass, mud, water, oil, or food stains, these elements can leave unsightly marks on light-colored concrete, making the surface appear dirty.
The 1600-WHITE series of water-based, white-pigmented concrete curing compounds are wax-based dispersions with selected white pigments. When properly applied, 1600-WHITE forms a premium-grade membrane, which optimizes water retention.
Why is my concrete turning white? Efflorescence is a white salty residue caused when too much moisture is moving through the concrete. As the concrete dries and its moisture rises upwards through the slab, it brings salts within the concrete to the surface as well.
Normally, two coats of the white cement wash are applied to the surface. This, however, will be done with a gap of one day. You could take this a step further with a third layer for an ideal finish. While using white cement, there are a few key factors you need to keep in mind.
White Portland cement is made from raw materials containing little or no iron or manganese, the substances that give conventional cement its gray color. So the secret of the White cement is raw material. Apart from that only whitest chalk is used together with light colored sand in production of white cement.
Concrete by nature will shrink, but the extra water can cause it to shrink too much or quickly. When it has excessive shrinkage, it has nowhere to go and the pressure from cement contracting against itself will cause cracks.
