TWO-LAYER BEAMS OF REINFORCED CONCRETE AND STEEL-POLYMER CONCRETE

CONCRETE SLABS, 10 X 20 X 120 CM. IN SIZE WERE CAST BY USING 1:1.45 CEMENT-RIVER SAND MIXTURE AND WATER-CEMENT RATIO OF 0.48. THE SLABS WERE REINFORCED WITH STEEL RODS. SOME OF THE SAMPLES WERE COATED WITH A MIXTURE OF POLYMER FILM SHORTLY AFTER POURING AND COMPACTING BY VIBRATION. IN SOME CASES THE REINFORCEMENT WAS PRESTRESSED BEFORE POURING. THE POLYMER-CLAD SLABS HAD MUCH HIGHER RESISTANCE TO CRACKING AND IN MOST CASES THEY DID NOT REQUIRE PRESTRESSING. THE THICKNESS OF THE POLYMER LAYER IS DICTATED BY THE CONSTRUCTION REQUIREMENTS AND ECONOMIC FACTORS. IT IS IN THE 6-20 MM. RANGE. /AUTHOR/
