The adverse effect has been formed: (1) The formwork will be removed too early, and the formwork will be pressed against the test block when it is formed according to the specifications, that is, the wall. Don't do this to the roof, it will cause problems. Dismantling the formwork too early and the later maintenance can't keep up, which will lead to strength loss; (2) You use too much cement, and the hydration heat is relatively high; (3) Hydration heat is a normal cement reaction, and generally does not cause adverse effects. If there is any influence, it mainly means that the critical temperature difference of concrete does not exceed 25 degrees, which will cause internal cracks in concrete. It's summer now, and the temperature outside is quite high, and the temperature difference will not exceed 25 degrees. (4) In the end, it seems that your water-cement ratio is wrong. Generally between 0.45 and 0.5. Yours is very tall Strength will be affected.
