Our take on the Quikrete 100680 Crack Resistant Concrete Mix, 80 Lb

Quikrete Crack Resistant Concrete Mix is an 80 lb bag of ready-to-mix concrete rated at 4000 PSI, blended with synthetic fibers that replace wire mesh in slab-on-grade work. It meets ASTM C387 compressive strength and suits slabs over 2 inches thick, from sidewalks and driveways to footings, curbs and equipment bases. The fiber reinforcement is the main draw against plain Quikrete Concrete Mix: you skip the mesh step and get better crack control, at the cost of a slightly stiffer mix and a rougher surface finish. It is a solid pick for both first-time pourers and trades who want one bag that handles structural and non-structural flatwork.

About the Quikrete 100680 Crack Resistant Concrete Mix, 80 Lb

Quikrete Crack Resistant Concrete Mix is a 4000 PSI blend of stone or gravel, sand, Portland cement, special synthetic fibers and other ingredients approved for use in concrete. It comes in an 80 lb bag. The mix exceeds the compressive strength requirements of ASTM C387.

The synthetic fibers reduce cracking caused by drying shrinkage. They also remove the need for wire mesh in slab-on-grade construction. The mix has good workability and impact resistance, and it suits both professionals and first-time users.

Use it for structural and non-structural concrete more than 2 inches (51 mm) thick. Typical projects include driveways, sidewalks, floor slabs, curbs, steps, ramps, walkways, poured walls and footings. It also works for tool shed bases and appliance or equipment bases.

Questions and answers

Does this replace wire mesh?
Yes. The synthetic fibers are designed to reinforce slab-on-grade pours so you can skip wire mesh.
How thick does the pour need to be?
Use it for concrete over 2 inches thick. Thinner pours are outside its intended use.
What strength does it reach?
It is a 4000 PSI blend and exceeds the compressive strength requirements of ASTM C387.
Can I use it for footings and structural work?
Yes. It is rated for both structural and non-structural applications, including footings, curbs and poured walls.
How much area does one bag cover?
Coverage depends on slab thickness; an 80 lb bag yields roughly two-thirds of a cubic foot of mixed concrete.
How does it compare with plain Quikrete Concrete Mix?
It adds fiber reinforcement and a higher strength rating, so it resists cracking better and removes the mesh step, but it is stiffer to finish.
