Based on the attached photos, it is likely that the concrete has experienced a chemical reaction due to an imbalance of chloride (Cl) and sulfate (SO₃) levels, along with Alkali-Silica Reaction (ASR). Additionally, environmental factors such as freezing and thawing have likely contributed to the observed damage.

Stream-curing of prestressed poles @Poles And Concrete Ltd. to achive 7-day concrete strength under conventional moist curing within 8 hours! Outline of Steam Curing Steam curing is a method for accelerated curing whereby concrete is cured in hot steam to obtain the required strength early. Concrete that has been subjected to steam curing is called steam-cured concrete. The initial strength of concrete is significantly influenced the maximum steam temperature and the temperature duration. The higher the maximum steam temperature, the earlier the concrete can be removed from the form and the larger the number of concrete production cycles (repetitions of forming and de-forming) per day. Generally, concrete plants produce ordinary-sized concrete products in 1.5 to 2 cycles/day and large-sized products in 1 cycle/day. The minimum strength required of concrete at the time of de-forming is 10–12 N/mm2 and 15 N/mm2 for ordinary- and large-sized products, respectively. In the case of a prestressed concrete product, the required strength is 35 N/mm2 or more because a prestress is introduced to it during de-forming. Therefore, many prestressed concrete products are made in 1 cycle/day. There are cases in which concrete products are shipped early when the required strength is obtained. Usually, however, concrete products are not shipped till they reach the age of 14 days (28 days for certain types of concrete products) #concrete #curing #steamcuring #psc #prestress #earlystrength #precast #civil
