The often specified seven-day curing corresponds to approximately 70 percent of the specified compressive strengths. There are a few reasons why this might happen: After completing the CAPTCHA below, you will immediately regain access to the site. An intriguing feature of concrete is that its strength can increase steadily over time, meaning its sturdiness is always growing year by year. Quick-dry uses low water and a mix of cement for quick drying while industrial concrete mixes might take longer. Thanks for the question.
