Cementitious Powder Addition to Concrete Mixtures for Rapid Pavement Repair

CHEM-CRETE® CEMENTIX® CEM 20M, is a unique, durable and high strength, cementitious powder product that is ready-to-add to a specific concrete mixture for rapid repair of concrete pavement. It is a dry powder mixture composed of specialty mineral powders integrated in environmentally friend product. CHEM-CRETE® CEMENTIX® CEM 20M is designed to be used as a powder addition for preparing concrete mixture specified in table 1 for patching of pavements after it is added to the concrete mixture. For some applications, a lower w/cm ratio can be used (e.g. 0.36).



CEMENTIX® Based Concrete is a workable and a very fast curing concrete that achieves a compressive strength higher than the typical requirement of 20M in two hours. Then, the CEMENTIX® Based Concrete mixture provides a solution to the problem of pavement closure for repair and curing.


CHEM-CRETE® CEMENTIX® CEM 20M can be used for preparing concrete for repair and patching materials for all types of concrete pavement applications.  It is significantly a cost-effective product for the repair of:


  • Airports
  • Highways
  • Ports
  • Bridges
  • Sidewalks & drives
  • Parking surfaces



CEMENTIX® CEM 20M-Based Concrete (described in Table 1) has the following advantages

  • Compatible with concreting materials, 100% green and environmentally friend.
  • Easy to mix and apply.
  • Applicable to all types of concrete pavement structures.
  • High workability with a slump in the range of 3-5 inch (7.6-12.7 cm).
  • Sufficient time after mixing for placement (25 minutes).
  • Minimal temperature rise
  • Achieves very rapid strength gain (about 40 MPa (5800 Psi) within the first 2-4 hours according to ASTM C 39). The early strength development for as shown in Table 2.

  • Achieves a very fast curing concrete with a rapid development compressive strength curve as shown in Fig. 2.

  • Meets the requirements for the Modulus of Rupture (see Fig.3)
