The entrance to our house consists of wood stairs leading up to a cement landing, approximately 3'x 3'. Instead of demolishing it to replace it, we were hoping to lay a wood fixture overtop and then attach that to the cement. I am curious as to what could be used to attached the wood to the cement?

There is another way by using special screws made for concrete. Several brand names are TapCon, Drillcrete, and ConSert.

These screws are installed by drilling a pilot hole through the wood and into the concrete (using the masonry drill bit provided) and then driving in the screw using a power drill.

The screws are made from a coated, hardened, steel that will tap threads into the concrete as they are screwed in. They are available in both hex head or flat head styles and either 3/16" or 1/4" diameter. The flat head style will work best for your application.

You'll want to use a pressure treated wood everywhere that will be making direct contact with the concrete, and all the new available pressure treated woods will corrode most fasteners very quickly. i don't know that they make a hardened nail for it. Tapcons have a coating which will not corrode.

alternately you might be able to use cedar, which will take a normal fastener. you could use cut nails and not have to buy the power nailer. You only need 3/4 inches of the nail in the concrete, a six penny nail for 5/4 decking is sufficient. But thats a good way to make ugly if you screw up, those nails like to decide to not drive at the last second, and not come out. there are exterior glues for concrete too, but i don't know about using them in your situation
