CONCRETE
For a typical 25kg bag of cement, you'll need approximately 2-3 liters of water to mix into concrete. This amount is a general guideline, and you might need to adjust it slightly depending on the specific type of concrete you're using and the desired consistency.
Here's a more detailed breakdown:
- General-purpose concrete:
Roughly 2 liters of water per 25kg bag is a good starting point. You’ll need a bit more for rapid set mortar
- Workability and strength:
Adding too much water will reduce the strength of the concrete, while adding too little will make it difficult to work with.
BUILDING AND PLASTERING MORTAR
For building and plastering mortar, a good starting point is to use roughly 3 liters of clean water per 25 kg bag. Adjust the water amount based on the type of mortar, how it's being used, and the desired consistency.
Start with less and add as needed :
- Mixing:
When mixing mortar, it's generally recommended to add the water gradually, mixing continuously until the desired consistency is achieved. Over-mixing can weaken the mortar, so it's important to avoid over-mixing.
- Using Mortar:
Mortar should ideally be used within a reasonable timeframe after mixing, as it can lose its workability over time.
GENERAL INSTRUCTIONS
Start with a Dry Mix:
- In a wheelbarrow or on a clean mixing board, mix the sand and cement together thoroughly until evenly combined.
- You can create a mound with a crater in the middle for easier water addition.
Slowly Add Water:
- Gradually add water to the dry mix, starting with about ¾ of the required amount.
- Add water slowly, mixing continuously, until the desired consistency is achieved.
- The amount of water needed varies depending on the type and moisture content of the sand.
Check Consistency:
- Ensure the mortar is not too wet or too dry, as both extremes can affect its strength and workability.
- The consistency should be creamy and easily spreadable.
