![]() ![]() Cracking and breaking observed in blocks on an existing breakwater agree very well with the cracking patterns predicted during the analyses. Specifically, the analyses indicate that blocks may lose shape as their corners break off, or they may fracture completely through the thickness and fall apart. Analyses showed that temperature differentials do have the potential of creating stresses sufficient to crack the concrete. Several parameters were varied in the analyses, including the volume of the blocks, the concrete mixture properties, formwork type, stripping time, and ambient conditions. To simulate the hardening process at the macro scale, the data were used in finite element analyses, which were used to evaluate temperatures and stresses. Concrete in breakwaters, jetties, groins and other marine structures, the function of which is to absorb the energy of waves, must be con-structed to resist truly enormous pressures and instantaneous impact. Tensile and compressive strengths and adiabatic temperature development were evaluated for the concrete mixtures during the initial 7 days of curing. To study the influence of fabrication practices on cubic armor units, six different concrete mixtures were first evaluated using small test cubes. Historically, resistance to wave action has been the main design criterion for large concrete armor units. Mound with superstructure or composile breakW 3 wall breakw ater 4.
