PLASTCRETE FOR TRAFFICABLE CONCRETE REPAIR
Applied concrete floor on a parking lot was frozen during of next night. The surface of the floor was severely
disintegrated on a depth at 15 mm with easy removable concrete layers. The uniqueness of this project is in
repair of damaged concrete by thin concrete layers at 10 mm to 40 mm. Heavy trafficable area required highest
possible adhesion of that layer to the damaged concrete, compressive strength at 35 MPa, and water
impermeability no less than W8. Our mix design of PLASTCRETE exceeded all expectations.
Below is a technique of repair of damaged concrete.
1. Choose test area at 40 SF or 4 m2.
PLASTCRETE MIX DESIGN
MATERIALS MASS, KG VOLUME, M3 NOTICE
Ordinary Portland Cement 200 0.063
Gravel D =2.5 mm ÷ 3 mm 250 0.1058 Not larger than D = 3.5 mm
Coarse Sand #16 550 0.2275
K100® 2 Liters / CM 2.15 0.0020
Water 95 0.095 W/C = 0.475
Total 1097 0.493 D = 2222 Kg/m3
ESSENCIALS AND CURING
1. Do not use curing and heating/cooling techniques.
2. After application, do not provide curing procedure and do not use curing compounds.
3. Do not cover fresh PLASTCRETE with any films or blankets.
4. Achieved results: Compressive Strength at 50 MPa
Tensile Strength at 11 MPa
Water impermeability at W12
Test results are available for your review and cosidiration.
2. Prepare KALMATRON® KF-G in accordance with instruction. Sprayed on a damaged concrete surface it provide adhesion of new concrete layer to old one.
3. Spray that solution on damaged concrete as .025 GL/SF or 1 Liter per 1 m2.
4. Prepare PLASTCRETE in accordance with mix design.
5. Apply PLASTCRETE no later than after 30 minutes.
6. Check test repair area after 12 hours and continue application.
ESSENCIAL: Preparation of concrete surface for repair by flame heating is a history now.
Just spray KALMATRON® KF-G.
All joints were restored with 10 mm thick layer of PLASTCRETE to repeat initial design of parking lot.

SANDCRETE INSTALLATION
1. Prepared first batch must be no smaller than 250 Kg.
2. Turn on mixer no less than for 1 minute.
3. First rotations could be hard, then don’t panic and continue mixing until 1 minute expires.
4. In a case of a batch stiffness use flat-plate vibrators for SANDCRETE flattering.
5. Continue mixing during of application. Do not stop mixer.
6. Apply layer from 10 mm to 40 mm thick only. For thicker layer we have to make adjustments
to this mix.
