How mortar differs from concrete
Mortar is a fine bedding paste for joints, while concrete is a stony mass with coarse aggregate.
When the purchase is complete, return to the original window. It will refresh.
From the opening
Mortar is a workable mix of binder and sand, packed into the joints between bricks or stones. Concrete is binder, sand, and coarse stone, cast as a mass that can form a footing, a wall, or a slab by itself. The opening covers sand and binder in the joint, coarse stone makes concrete, and grout sits between the two.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
