Using a cement mixer for mortar involves a straightforward process that ensures a consistent and well-mixed batch. Here's a step-by-step guide:
Preparing Your Mixer
Before you begin, ensure your cement mixer is on a level surface and is stable. Check that the drum is clean and free of any hardened material.
Loading the Mixer
- Start with Water: Add a portion of the required water into the rotating drum.
- Add Cement: Gradually add the required amount of cement.
- Add Sand: Introduce the sand in stages, allowing the mixer to incorporate each addition thoroughly.
- Add Lime (If Needed): If your mortar recipe calls for lime, add it after the sand.
- Add Remaining Water: Slowly introduce the remaining water until you achieve your desired consistency. This process is iterative and you should add water until the mortar is workable.
Mixing the Mortar
- Allow the mixer to run for several minutes, ensuring all materials are thoroughly combined.
- The ideal consistency for mortar should be workable – thick enough to hold its shape but smooth enough to spread easily.
Discharging the Mortar
According to the YouTube video "How to use a Concrete Mixer," once the mix is ready:
- Keep the drum turning.
- Tip the drum forward to discharge the contents.
- After you have emptied the mixer, return it to an upright position.
Step | Description |
---|---|
1. Preparation | Place the cement mixer on a level surface and ensure the drum is clean. |
2. Add Water | Pour a portion of the required water into the mixer. |
3. Add Cement | Gradually add the cement, allowing the mixer to combine it with the water. |
4. Add Sand | Introduce the sand in stages for thorough mixing. |
5. Add Lime | If required, add the lime after the sand is mixed. |
6. Add Remaining Water | Add remaining water until desired consistency is reached. |
7. Mix | Let the mixer run to fully combine all materials. |
8. Discharge | While the mixer is still turning, tip the drum to pour out the mortar, then return it to the upright position. |
Tips for Success
- Measure Accurately: Use precise measurements for cement, sand, lime, and water to get the right mix.
- Add Water Slowly: Add water gradually to avoid making the mixture too wet.
- Check Consistency: Check the mortar's consistency as you mix; it should be smooth and workable.
- Clean Mixer After Use: Clean the cement mixer promptly after each use to prevent material from hardening inside.
