Products for ultimate sustainable concrete floors Consolideck® LS® Abrasion Resistance - Taber Abraser LS® & competition vs. Untreated Control TEST RESULT Taber Abrasion Testing H22 Wheel, 1000 gram load using ASTM C1353 % Improvement vs. Control modified for concrete. Concrete Treated with Consolideck® LS® 59 Concrete Treated with Competitive Product A 29 Concrete Treated with Competitive Product B 29 Concrete Treated with Competitive Product C 37 Concrete Treated with Competitive Product D 42 Concrete Treated with Competitive Product E 46 Notes This test establishes abrasion resistance of concrete to simulated foot traffic using grinding wheels under specifed loads for a specified time. The results ® ® LS show LS-treated concrete reduced abrasion loss by 59% compared to untreated concrete. Other concrete hardeners had less reduction of abrasion.
