ASTM C 595 on blended cement includes other pozzolanic or slag materials in the cement. There is no inherent reason why white cement could not be produced under C 595. However, byproduct ingredients like pozzolans or slags may not be color controlled to the same degree as portland cements, so a blended cement product is more likely to vary in color. Therefore, white cement would probably not be specified under this standard. Now that you know exactly how to create some test mixes and compare to your existing mortar to find a colour match, it’s now just a question of getting it done, but before you make a start there are a few further points to be aware of: One thing to be aware of is that it is important to mix the dye into the cement before you add the water.

If you cannot locate the sand then talk to the builders merchants and even the local quarry to find out how many local building sands there are available. Now, pour your sand solution gently over the top. The tights will act as a sieve, allowing the remaining water/acid solution to drain off, leaving you with just your sand. Another environmental benefit of white cement is its colour. The brilliant white finish reflects more light and, therefore, retains less heat than other types of cement. As a result of this, when used to make white concrete, structures will remain cooler in summer and minimise the amount of energy required to regulate temperatures. This not only reduces energy costs but also the overall carbon footprint of the structure. White Cement vs Grey Cement: What is the Difference?Don’t be tempted to use anything too heavy or blunt for this. If you get too carried away you will grind the actual sand particles down too much and have nothing to compare other than a pile of dust. Step 3 – Mix Muriatic Acid Solution Concrete mix coloured grey due to colour of the cement used What Other Factors Affect Mortar Colour? Accelerators help to speed up the setting and hardening process of cement and mortar, whilst retarders slow it down. If you’re looking for a concrete waterproofer additive, many of our accelerators, retarders and plasticisers include waterproofing and frost-proofing qualities as an added benefit.

The key to this whole process is consistency with the mix ratio. If you have a lot of pointing or repair work to do then to maintain a consistent colour match from your first mix to your last, everyone has to be the same. Before we actually start looking at mortar and cement colour matching techniques, it’s important to understand exactly why mortar and cement colours can vary so drastically.The color of white cement is determined by its raw materials and the manufacturing process. Metal oxides, primarily iron and manganese, influence the whiteness and undertone of the material. You can now take this container to your local DIY sheds, builders merchants or other locations that sell sand so that you can compare it and hopefully get a close if not exact match. This may take a day or so but you will need to be patient as each one needs to be fully dried to get an exact colour. On the topic of light coloured mortar, did you know you can also get white cement? If not, indeed you can. White cement is created using raw materials that don’t contain any (or at least very little) manganese or iron, the components that give traditional cement its grey colouring.

White cement is naturally waterproof, and will not require any additional waterproofing measures when used in a building. Its waterproof nature, as well as its ability to withstand much higher temperatures than other types of cement (thanks to its reflective white finish), make white cement a brilliantly versatile and dependable building material that can withstand the harsher elements when used on exteriors and the wear and tear of interior living. Is White Cement Eco-Friendly? So as you can see, not only does the colour and type of the sand that used in a mortar mix affect its colour but so does the cement and the presence of lime if it has been used. How do I Know What Colour Sand was Used in the Original Mortar? Different types and colours of sand – Image courtesy of sandatlas.org Does the Colour of the Cement Matter? Firstly, get a couple of samples of mortar. If the joints that you’re looking to repair are particularly damaged then you should be able to prise some chunks of old mortar out.

Method 1 - Surface Coloring

This is easy enough to do but does involve a little time and patience as you will need to create a range of different mixes using different ratios of cement to sand. Under no circumstances should you ever change the cement to sand ratio of a mortar mix for a new mix so that it’s different from any existing mortar just to ensure a colour match! This may affect structural integrity This method involves mixing concrete with added pigment. Pigments usually come in small boxes or bottles. Quikrete makes a 10-ounce cement dye that mixes with 2 60# or 80# pounds bags, saving you the trouble of calculating the tint yourself. Mix the Concrete

Essentially you have to repeat the above process e.g. creating several different mixes but adding the required dye or tone colour in different quantities until you have a decent colour match. For this reason it is fairly essential that you identify and use the same sand that was used for the original mortar, although often this isn’t always possible as pits, mines and quarries close or run out of materials, local suppliers shut down, sand supplies are sourced from abroad etc. The next part is a waiting game! You will need to leave the solution for 2-3 days for the Muratic Acid to get to work on the on the cement and dissolve it (and also any lime that may also be present). Type II: When compared to other varieties of mortar, Type II mortar stands out. Only when applied to a surface with a typical concentration of sulphates will it provide any noticeable benefit. However, in terms of typical masonry, it is totally unimportant.Aside from the techniques we have run through above for extracting sand from the original mortar, which is very effective by the way, you can also undertake some local research. Place the sand on an old sheet/cloth and leave it somewhere out of the way to fully dry off. Once dry, pop it into a clear sealed jar or container. Step 7 – Match the Sample If you have read through the above you should now know exactly why mortar can vary in colour and how a fresh mortar mix can be a totally different colour to existing mortar, it’s now time to look at the methods that can be used to actually colour match cement and mortar.
