Title: ABSORPTION OF CONCRETE IN WATER AS AFFECTED BY AGGREGATES - ITS ULTIMATE EFFECT IN EXPANSION OF ROAD SLABS
Accession Number: 00217816
Record Type: Component
Abstract: PUBLISHED INFORMATION ON THE ASBORPTION OF CONCRETE IN WATER AS AFFECTED BY AGGREGATES IS REVIEWED. IT IS THOUGHT THAT THE KIND OF COARSE AGGREGATE USED MAY BE A FACTOR IN THE BUCKLING OF PAVEMENTS. THE FOLLOWING ITEMS ARE SUGGESTED FOR RESEARCH: (1) EFFECT OF POROSITY OF COARSE AGGREGATE ON STRENGTH OF CONCRETE WHEN DRY AND WHEN SATURATED (2) EFFECT OF ABSOPRTION OF COARSE AGGREGATES ON BOND BETWEEN COARSE AGGREGATE AND MORTAR, (3) AMOUNT OF EXPANSION DUE TO ABSORPTION AND TEMPERATURE CHAMGES OF CONCRETE WHEN DIFFERENT COARSE AGGREGATES ARE USED KEEPING MORTAR CONTENT CONSTANT, (4) EFFECT OF DIFFERENCE IN MODULUD OF ELASTICITY OF COARSE AGGREGATE AND MORTAR, AND (5) EXPANSION OF DIFFERENT ROCKS DUE TO ABSORPTION.
