For the design of slabs-on-ground with fiber reinforcement, Chapter 11 in the American Concrete Institute’s (ACI) 360R guide provides detailed information and calculations.

This was followed, at higher loading, by circumferential cracks that connected the radial cracks. Increasing the GFRP reinforcement ratio from 0.71 to 1.62 percent raised the punching shear capacities ...

Q: Tim, my builder is telling me to forget about using reinforcing steel or mesh in my concrete driveway and patio. He says he’ll just add an inch of thickness and that’s good enough. W… ...

The FORTA-FERRO macro-synthetic fiber was used in a very large slab on metal deck project in Middleton, Del., that provided a working surface for the 2nd-level order fulfillment operations for the ...

The new findings show the design required that at least 25 percent of the slab reinforcement bars “be centered” and “pass over” each column, Bell said during the NIST presentation.

Install one-half-inch steel reinforcing bars 2 feet on center both directions in this slab. The steel will look like an empty sheet of graph paper before the concrete is poured.

Roughly two-thirds of the backyard of our new house is covered with concrete slab and so I thought I would go our there and break it up with a sledgehammer in advance of putting in a new garden. The ...

Your patio reminds me of two failed experiments I tried back when I was in my mid-20s. I thought I knew how to build a simple brick patio, but Mother Nature decided she’d teach me a tough lesson.
