Good ones Marc. Thanks

The concrete ones are for you!

some of these questions are shocking…

1 - Tap Water and Milk do conduct electricity because of their ions; but honey, vinegar, distilled water, and (light) fuels do not conduct electricity because they do not have free ions.
2- Conventional Fireplace Chimney
3. Hydration
4. Resistance is Ohms, Current is electrons flowing in same direction
5. Plastic cover will retain moisture to allow more complete and faster hydration, and can protect it from weather (rain, snow, etc.). That’s good. But it can discolor the concrete and will likely leave marks (imprint) on the finish. That’s not good.

Good questions. Everyone should have plenty of time to think about their answers this week :slight_smile:

  1. distilled water, honey, fuels and vinegar are all bad conductors or electricity.
  2. conventional fireplace chimney
  3. the chemical reaction between cement and water (known as hydration, this produces heat and is called the heat of hydration).
  4. resistance - current
  5. It can protect the new concrete from environmental cooling and heating fluctuations as it cures, and it helps resist uneven curing due to rapid moisture loss at the top. Has the possibility of permanently staining concrete due to air bubbles, water pockets and wrinkles trapped inside the plastic.

  1. Honey, distilled water, and fuels are poor or do not conduct electricity
  2. Conventional fireplace chimney
  3. Hydration
  4. Resistance, Current
  5. Plastic over poured concrete can help by slowing down the curing process but can also result in pockets of moisture making the concrete cure unevenly which leaves it appearing “stained” in spots.

1-A
2-Chimney
3-Hydration
4-Resistance, Amps
5-It causes hydration to slow down allowing the concrete to cure longer…Good!

  1. Honey, Vinegar, Fuels
  2. Chimneys
  3. Hydration
  4. Resistance, Direct Current
  5. Plastic keeps the concrete damp and helps the curing process.
    Plastic in contact with the concrete can cause staining & discoloring.
