Quikrete Crack Resistant Concrete Mix is a bagged, fiber-reinforced concrete for flatwork and structural pours at least 2 inches thick. Alkali-resistant synthetic fibers and an air-entraining admixture replace wire mesh in typical slab-on-grade work and improve freeze-thaw durability. It reaches 4,000 psi at 28 days and exceeds ASTM C387 strength requirements. It suits contractors and experienced DIYers pouring driveways, sidewalks, steps, curbs and equipment pads; against plain 4,000 psi mixes it trades a slightly coarser finish for built-in crack control.

Owners and trade users report strong, crack-free slabs and easy mixing, with fibers cutting out mesh work. Complaints center on the visible fiber finish and the coarse aggregate making finishing fussier than a plain mix.
Product Description
The QUIKRETE COMPANIES 100650 is a commercial-grade, crack resistant concrete mix formulated for structural concrete applications. Each 50-pound bag contains an air-entraining admixture combined with alkali-resistant reinforcing fibers distributed throughout the mix. These fibers reduce cracking caused by drying shrinkage, addressing one of the most common failure points in flatwork. The result is a mix with superior workability and finishing characteristics that does not require wire mesh reinforcement in typical slab-on-grade installations. It is suited for contractors, masons, and experienced trade professionals who need a reliable, high-performance concrete mix for structural pours.
This mix is designed for use in structural concrete applications including slab-on-grade flatwork where conventional wire mesh reinforcement would otherwise be required. The air-entraining admixture improves freeze-thaw durability, making the mix appropriate for both interior and exterior concrete placements. It is well-suited for residential and light commercial flatwork where crack control and workability during finishing are priorities. The 50-pound bag format is practical for job sites where mixing volume needs to be controlled or where ready-mix delivery is not practical.
Key Features
• Commercial-grade formula with air-entraining admixture for improved durability
• Alkali-resistant reinforcing fibers dispersed throughout the mix reduce drying shrinkage cracking
• Eliminates the need for wire mesh in typical slab-on-grade applications
• Superior workability and finishing characteristics for flatwork applications
• Designed for structural concrete use
Compatibility
Designed as a commercial-grade crack resistant concrete mix suitable for structural slab-on-grade applications where wire mesh reinforcement is typically required.
Installation Notes
Concrete mixing and placement should be performed by qualified masons or concrete contractors following applicable local building codes. Always power down or de-energize any adjacent electrical or mechanical systems before beginning concrete work in proximity to utilities. Do not add excess water to the mix, as this reduces compressive strength and increases shrinkage cracking. Follow ACI guidelines for proper curing procedures to achieve full design strength.
