POLYMERIZED LIGHTWEIGHT STRUCTURAL ELEMENTS

IMPREGNATION OF CONCRETE MATERIALS WITH POLYMERS WAS EXTENDED TO INCLUDE THE IMPREGNATION OF LIGHTWEIGHT FOAM CONCRETES. FILLING APPROXIMATELY 90 PERCENT OF THE EXTENSIVE VOID SYSTEM OF THE FOAM CONCRETE WITH A POLYMER INCREASED THE COMPRESSIVE STRENGTH FROM 202 PSI TO 3250 PSI, THE SPLITTING TENSILE STRENGTH FROM 30 PSI TO 1008 PSI, AND THE MODULUS OF ELASTICITY FROM 100,000 PSI TO 425,000 PSI. BEAM STRUCTURAL ELEMENTS WERE PARTIALLY IMPREGNATED TO PRODUCE A "SANDWICH PANEL" ELEMENT WHICH CAN UTILIZE THE FOAM CONCRETE CORE TO ACT AS AN INSULATOR AND AS A SPACER TO SEPARATE THE POLYMER IMPREGNATED SURFACE REGIONS; AND CAN UTILIZE THE POLYMER IMPREGNATED SURFACE REGIONS TO RESIST LOADINGS. THE SANDWICH ELEMENT PRODUCED THUS UTILIZES MATERIALS EFFICIENTLY TO SATISFY THE MULTIPLE FUNCTIONAL REQUIREMENTS OF LOAD AND OF ENVIRONMENT. /AUTHOR/
