POLYMER-MODIFIED FERROCONCRETE 5 A POLYMER-MODIFIED CONCRETE 300 AND POLYMER-MODIFIED FERRO-CONCRETE 302 IS PREPARED BY UTILIZING PREPACKAGED POLYMER MODIFIED MORTAR 306 AS A MODIFIER TO CONVENTIONAL CONCRETE 304. THE STRENGTH DEVELOPMENT OF PROPOSED POLYMER-RILODIFIED CONCRETE 300 IS SUBSTANTIALLY INCREASED. A RANGE OF QUANTITIES OF PREPACKAGED POLYMER MODIFIED MORTAR 10 306, WERE MIXED WITH CONVENTIONAL CONCRETE 304 OF 30 N/MM 2 STRENGTH TO PRODUCE POLYMER MODIFIED CONCRETE 300 AND THE POLYMER-MODIFIED CONCRETE 300 MOLDED OVER WIRE MESH 310 TO PRODUCE POLYMER-MODIFLED FERRO-CONCRETE 302. THE MATERIAL BEHAVIOR IN TEMIS OF COMPRESSIVE STRENGTH AND TENSILE STRENGTH, TOGETHER WITH DENSITY AND SLUMP IS IMPROVED SIGNIFICANTLY BY INCLUSION OF VARIOUS QUANTITIES AS PERCENTAGES OF PREPACKAGED 15 POLYMER MODIFIED MORTAR 306 TO CONVENTIONAL CONCRETE 304. PREPACKAGED POLYMER MODIFIED MORTAR 306 DOSAGES OF 5 TO 20RESULTED CONSIDERABLY HIGHER COMPRESSIVE AND TENSILE STRENGTH THAN THAT OF CONVENTIONAL CONCRETE 304. ON THE OTHER HAND FURTHER INCREASE IN PERCENTAGE OF PREPACKAGED POLYMER MODIFIED MORTAR 306 RESULTS IN LESS STRENGTH TO POLYINER-MODIFIED CONCRETE 300 AS WELL AS POLYMER-MODIFIED FERRO-CONCRETE 302. 20 25 30 |
