Concrete Video: 6 Common Mistakes of Ready-Mixed Concrete

, engineers! 6 Common Mistakes of Ready-Mixed Concrete, don't Step on the Pit Again! The first mistake is that the greater the slump, the easier it is to pump. In fact, 150-200mm is enough. If it is too large, it is easy to isolate and block the pipe. The second mistake is that the higher the water reducing rate and the lower the dosage of admixture, the better. Unreasonable proportion will affect the production efficiency and concrete stability. Misunderstanding three, winter mixed with antifreeze does not need heat preservation, maintenance is not in place will lead to strength damage. Fourth, if the test piece is not qualified, the concrete will be judged to be unqualified, and sampling, curing and other links may affect the results. The fifth mistake is to take the laboratory condensation time as the actual time on the spot, and the scene environment will change the condensation speed. Misunderstanding six, the loss side is to blame the short weight of the mixing station, construction loss, drawing errors and so on will also cause the deviation of the volume. Only by avoiding these misunderstandings can we ensure the quality of the project and avoid detours!
