Is Quikrete as strong as concrete?

Does bags of cement have a shelf life?

Most people don't seem to realise that cement comes with a shelf-life. Cement is a hygroscopic product, which means it absorbs moisture. This characteristic of cement makes it imperative that it is used before its 'best before' date to ensure a durable structure. The shelf life of cement is 3 months.

What happens if Quikrete gets wet?

Quikrete and any other bag of concrete or cement can not get wet. When water is added to a dry concrete mix a chemical reaction occurs which causes it to harden. Once the bag becomes wet, the concrete inside absorbs that moisture, the chemical process begins and the concrete permanently hardens and becomes useless.
