Ok, maybe one more thing... Tobin, I know concrete can dry under water, but not any concrete. In fact we know that the Romans developed concrete that dries under water.
Concerete does cure, but it starts with water in it. Are you saying that all of the hydrogen and oxygen molecules are converted in the (chemical) curing process, and none can be left as H2O?
I used the term drying as a general term that everyone would understand, and perhaps I should have said set. Itâs as much the tone of the response as anything that caused me not to let go.

I m not looking for any comment from you, let alone an insult.
Iâm afraid you seem to be limited by your all or nothing mentality M_J. When something dries it doesnât mean that there is no water left in something. There is still moisture in our clothes when they are âdryâ. If you assert that there is no water at all in a slab of concrete then I can get a Cementitious Materials Scientist to prove you are wrong. Even I am aware of the hydration/curing process. He told me about it two to three years ago when I laid my third (I think) slab for my patio.
You are clearly less educated than some gave you credit for or, as you have demonstrated, you think you are.
Enough said, except to say there was no need to be abusive.

Buffy can just Google it. Iâm done using time to explain it. If your concrete dries out, you are an idiot.
It's actually quite complicated sometimes as internal temperatures can exceed 100 centigrade as well - obviously for larger concrete structures but thought I'd mention that as well whilst we were discussing concrete.....
No, concrete doesnât âdryâ, it hardens by chemical reaction.
It will happily harden underwater.
Not that any of that was relevant, although interesting, I would say that I thought that as the concrete hardens the water inside it evaporates through its surface causing water from deep within the concrete to moves through the capillaries outwards/upwards to the surface to replace it.
With all due deference, concrete does dry but not by your limited definition.
Buffy
Concrete doesnât dry, it cures. The strength over time curve is pretty much the same for all concrete (what % of itâs final strength is achieved after so and so many days). This is also assuming curing under correct conditions, not too hot, not too cold, donât let it dry out, etc .....
You can use readers or accelerators, but this can affect final strength.
The pad is a very simple concrete construction, pretty much the simplest. Put some boards around the edges, some steel in the middle, and concrete run down a shoot. Finish surface and water a few days or cover with plastic sheet (we want the water used up in the chemical curing, not to evaporate and dry out).
Been waiting for sub ÂŁ1 but looks like thatâs a floor now so added at 102.6. Now watch it go to 95p!
Trek
I surmised as much M_J, but wasnât certain, as your original comment suggested a fixed drying time. I wasnât sure if itâs because you knew the specs for the pad though.
Buffy
You can also change the concrete quality for more strength in the same thickness. But letâs just say to keep it simple, your driveway is a vastly different compressive strength mix than whatâs used on the foundation to a skyscraper.
So, they can have a pad loadable in 7 days if they want. +2 = 9 days from Friday. Doubt they would push it much under that because it starts to be quite diminishing returns.
The pad would obviously be designed for the loads it is expected to carry. If you wanted to utilize the pad quicker (at say 7 days from pouring (65%) instead of 14 days (90%), you could simply increase the thickness and beef up the rebar so that your new pad design at 65% could carry the same load as the older design at 90%.
Different rigs will be different loads, different soils underneath have different properties (which you obviously compact), so no, the pad thickness is not always the same in every drilling location around the world. You can also change the design thickness to either save money, or save time.
The concrete forms and rebar used in these pad are very simple and quick to install. Pour is done a day. Itâs not unreasonable to have the pad finished poured two days after this picture was taken, but that depends on having materials and manpower available.
Somehow I think you know all of this already Buffy. But yeah, I studied civil engineering and ended up in the oil business for 25 years as well as owning a small construction company.
Hi M_J,
â Need to dig some holes for the pits and pour the concrete pad. Say three weeks work even allowing for 14 days cure (90% strength) on concrete, so early May is very possible. 7 days cure is 65% strength, so curing time could be less allowing rig setup sooner, so in 14 days start rigging up. â
Is the pad always the same thickness please?
Buffy
Royston pad pic on Twitter ....... how lovely and appreciate TXP showing us the pictures of progress.

To really benefit big time from the increase in oil prices a company needs to already be a big producer and have increases in output confidently known to be happening in the near future. Future oil prices are always uncertain, not just because of fundamental supply and demand issues but also given that key role of OPEC + in rigging the price and uncertainty about the key roles of Saudi Arabia and Russia. An inevitable consequence of this situation is that stock markets are very likely to heavily discount 'jam tomorrow' scenarios and focus on short term prospects.
I have what for me is a significant holding in Touchstone. Up until January this year the progress of the share price clearly reflected shareholder acceptance of a very credible 'jam tomorrow' scenario and a strong belief that the company was well managed. The 'jam tomorrow' scenario is in my view still intact even though it may now contain a different mix of gas and oil than originally envisaged.
What has been lost is confidence in the ability of Touchstone to deliver results to their own quoted timescales and some doubts at least about their geological expertise and technical ability when drilling wells. Sadly confidence is a fickle concept and it will take both time and more than one success to rebuild in this instance. Touchstone is right to stress that exploration is a bumpy ride, arguably needs to be more realistic about timescales that are not within its control and focus on getting production increasing so that it remains self financing. In the meantime shareholders need to focus on the potential long term value and stop imagining that each RNS will create instant big profits via huge increases in the share price.
And letâs not forget the last RNS Just Days ago....

CASCADURA DEEP-1 WELL TEST CONFIRMS LIQUIDS RICH NATURAL GAS
CALGARY, ALBERTA (April 12, 2021) - Touchstone Exploration Inc. ("Touchstone", "we", "our", "us" or the "Company") (TSX, LSE: TXP) announces the completion of flowback testing of the Cascadura Deep-1 well, confirming a liquids rich natural gas discovery. Touchstone has an 80 percent operating working interest in the well, which is located
Listen from 3.53 onwards very exciting...
PB... is still very optimistic

Spawny this is more than Jam today at these very low share prices..
With outstanding assets itâs virtually a give away.. chinook which is now valued as a ÂŁminus by the markets...could even turn out to be a big oil well..
Coho just weeks away from coming online and Royston Also in weeks...
What is not to like... only days ago you posted this....22
Having got out of these at 160-170 I have to admit to jumping back in quite heavily this afternoon after the flare picture. I couldn't manage to buy all I wanted but got some decent chunks towards the end. I feel confident we'll get some news next week.
