To concrete in round posts, start by digging a hole that is at least one-third the length of the post and wider than the post diameter. Place the post in the hole and use a level to ensure it is straight. Mix the concrete according to the instructions and pour it into the hole around the post. Use a shovel to compact the concrete and remove any air pockets. Allow the concrete to set and cure according to the manufacturer's instructions before attaching any fencing or other structures to the posts. **

To apply concrete on concrete, the existing surface must be clean, free of debris, and properly moistened. A bonding agent or primer should be applied to the existing concrete to ensure adhesion. The fresh concrete mix can then be poured or pumped onto the existing surface and spread evenly using a screed or trowel. It is important to properly cure the new concrete to prevent cracking and ensure a strong bond between the two layers. **

Yes, it is possible to pour new concrete over old concrete as long as the existing concrete is in good condition and properly prepared. The old concrete should be clean, free of any loose debris, and roughened to provide a good bonding surface for the new concrete. Additionally, a bonding agent may be used to ensure a strong bond between the old and new concrete. It is important to consult with a professional to assess the condition of the existing concrete and determine the best approach for pouring new concrete over it. **

To concrete the natural ground in the basement, you will first need to excavate the area to the desired depth. Next, you will need to compact the soil to create a stable base for the concrete. After that, you can lay a layer of gravel or sand to further stabilize the ground and provide drainage. Finally, you can pour and level the concrete over the prepared ground to create a solid and durable basement floor. **

Whether to round down or round up depends on the specific situation and the context in which the rounding is being applied. In general, if the decimal portion is less than 0.5, it is common to round down, and if the decimal portion is 0.5 or greater, it is common to round up. However, it is important to consider the impact of rounding on the overall accuracy and fairness of the calculation. In some cases, rounding up may be more appropriate to ensure that the result is not underestimated, while in other cases, rounding down may be more appropriate to avoid overestimation. Ultimately, the decision should be based on the specific requirements and goals of the calculation. **

Round numbers are called "round" because they are easy to work with and understand. They are multiples of 10, which makes them easy to divide, multiply, and round off. Their simplicity and ease of use make them "round" in the sense that they are smooth and convenient for calculations and estimations. This term has been used for centuries to describe numbers that are easily manageable and divisible. **

For setting lawn edging stones, garden concrete would be the better option. Garden concrete is specifically designed for outdoor use and is more durable and weather-resistant than concrete screed. It also has better adhesion properties, making it more suitable for securing the edging stones in place. Additionally, garden concrete is often formulated to be more resistant to cracking and shifting, which is important for maintaining the integrity of the lawn edging. **

It is unclear whether the concrete ring was poured with the wrong concrete based on the information provided. The concrete ring may have been poured with the wrong concrete mix if it did not meet the required specifications or if it resulted in structural issues. Further investigation or clarification from the relevant parties would be needed to determine if the wrong concrete was used for the project. **
