Guide For Your Cement Needs

Considerations before buying cement 

The term cement and concrete are used interchangeably and that is because, cement is the defining ingredient of concrete. Your selection of cement determines the characteristics of your cement and therefore, selection of the right cement for the right task is very important. There are some considerations that you need to be clear about before buying the cement for your construction needs.  

  1. Firstly, it is important that whatever your need for cement may be, always go for the authorized company outlets of concrete suppliers. Do not buy cement from middle men. If you must, go for companies or personnel that are well-reputed in the business and you won’t have to doubt the quality of material you buy from them. 
  2. Read all the details about the cement carefully and match those with the requirements given by the site-supervisor. You must pick the right grade of cement for your construction need.  
  3. When you buy the cement, carefully inspect the bag for any signs of re-stitching. This ensures that the cement you’re buying is of the promised quality. Re-stitched bags of cement might be a sign of impurity.  
  4. Check the manufacturing date of the cement. Avoid buying cement that was manufactured more than 3 months before the date you’re purchasing. The closer the date of manufacturing is, the better the strength or the cement. 
  5. Inspect the bag of the cement. Often the bags are hard due to the chemical reaction between cement and the moisture. Avoid those bags. 

Considerations before storing cement 

Storing the cement in the right environment is very important. A professional concrete suppliers Melbourne can guide you well about storing requirements when you buy the cement. However, there are certain guidelines that apply to all kinds of concrete.  

Humidity level 

The moisture in the environment plays a significant role in determining the quality of the cement when it’s time to use it. It needs to be away from any moisture. If the absorption percentage of the moisture rises above 5%, the cement can become useless. This is because the water content reacts with the cement.  

Their storage level 

When storing the cement bags, make sure you don’t place the bag on the floor. Use wooden planks along with a plastic sheet to place them at least 200mm away from ground.  

Do not use hooks 

Using the hooks can expose the cement to the environment and thus, increased chances of cement interacting with the water content in the air. This can damage the quality of cement.  

Stack wisely 

Cement bags are heavy and it is not possible to move them around when you need to use one. So, when you stack the stock, place them in such a way that you have access to each sack without moving the rest of them. Stacking one on the other can make it difficult to inspect the sack when needed.  

When you have leftover cement in a bag, make sure you seal the mouth of the bag that you use to store left-over cement.   

The specifications  

There are three categories of specifications of cement. In order to buy the right one for your need, it is important that you are aware of these specifications when you’re dealing with the supplier.  

The type of cement 

There are three primary types of cement. Talk to the site-engineer or the person supervising the construction to make sure you buy the right type. 

  • Ordinary Portland Cement 
  • Portland Pozzolana Cement 
  • White Cement 
  • Grade of cement  

The grade of the cement defines the strength of the concrete. The strength requirements vary according to your construction needs so make sure you know the grade you need.  

Any other special requirements 

There are some types of cement that are specialised for their task such as heat resistant, sulphate resistant etc. Talk to the person in-charge of construction about any special requirements of cement.   

Final tips in the order  

Summing it all up in a step-by-step guide, follow the below guidelines when buying cement.  

  1. Select the right type of cement and go through all the specifications carefully.  
  2. Carefully inspect the bag for any signs of damage or leakage. Also check for any lumps in the material. 
  3. Carefully inspect your storage place for moisture.  
  4. Store the bags as advised above.   
  5. When dealing with left-over cement, keep it away from moisture in air.
