What epoxy is used to bond concrete to concrete?
It can. You'd need huge amounts of the cement in relation to the aggregate. The sand acts as a filler to help the cement fill voids between the larger pieces in the aggregate. You can mix an appropriate amount of water with just the “portland cement” and let that harden without any sand or rock add.
