CONSTRUCTION OF MODEL ARMOR UNITS

TO DEVELOP A MODELLING MATERIAL AND PRODUCTION TECHNIQUES THAT WILL PROVIDE MODEL BREAKWATER ARMOR UNITS WITH THE FOLLOWING ATTRIBUTES AT REASONABLE MODEL SCALES: GEOMETRICAL MODELLING OF DOLOS, TETRAPODS, TRIBARS, AND SO ON; MASS AND INERTIAL MODELLING OF PROPERTIES OF ARMOR UNITS; STRENGTH MODELLING OF REINFORCED CONCRETE; MASS PRODUCTION AT RELATIVELY LOW ACQUISITION COST; EASY HANDLING AND STORAGE; STABLE STRENGTH PROPERTIES AND REASONABLE "SHELF LIFE". IT IS OUR BELIEF THAT A MATERIAL CURRENTLY REFERRED TO A MOD-CRETE MAY POSSESS THE POTENTIAL PROPERTIES TO ACHIEVE THESE OBJECTIVES. MODCRETE IS A SPECIALLY PREPARED MODELLING MATERIAL CURRENTLY USED SUCCESSFULLY IN THE CONDUCT OF PHYSICAL MODEL TESTS OF ICE INTERACTING WITH SHIPS AND OFFSHORE STRUCTURES. THIS MODELLING MATERIAL FOR ICE (MOD-ICE) WAS ORIGINALLY DEVELOPED BY DR. B. MICHEL IN THE EARLY 70S AND SINCE BEEN REFINED & IMPROVED BY THE ARCTEC GROUP IN LAST 10 YRS FOR USE IN MODELLING SEA ICE WITH THE PROPER GEOMETRICAL, MASS DENSITY AND INERTIAL PROPERTIES AS WELL AS MECHANICAL PROPERTIES OF FLEXURAL (BENDING) STRENGTH, CRUSHING STRENGTH AND ELASTIC MODULUS AND FRICTIONAL PROPERTIES.
