I just stumbled upon the question “Why is sand added to concrete? On Quora and so I think there might just be several other people out there with a similar question and so I decided to bring it closer for you my reader too.
On this Post, I’ll explain the reasons why sand is always added to concrete
Why Is sand Added To Concrete?
Because even sand grains on their own still has different sizes, the finer particles stat to fill up holes or pores that the bigger grains of sand could not fill
2. Also, Without sand (fine aggregate), we end up with excessively large holes which must be filled up with (expensive) cement paste.
So, we need more cement paste than we otherwise would. That costs serious money, and also leads to an excessive drying shrinkage figure.
5. Sand is usually abundant and when its just in the right proportion in a mix system, its aids workability. Just imagine a mixture of granite and cement without sand. Less workability isn’t it? Lol
Well, I’ve listed 5 reasons why sand is always added to concrete on this post, you can however suggest other reasons in order to enable us build a more reliable platform for other researchers.
