The oldest known concrete boat using steel wire mesh covered with sand and cement plaster was a dingy built by Joseph Louis Lambot Southern France in 1848. The boat was patented and featured in the 1855 World's Fair in France. In this study, the concrete boat using fiber wire mesh covered with cement, rice husk, silica fume, steel fiber, glass fiber wire, sand, water and superplasticizer was design and built in the material laboratory at Chaoyang University of Technology. The length, width, depth and thickness of the boat are about 60, 20, 10 and 1.5 cm respectively. The rice husk can absorb water ranging from 8% to 12% of unit weights, and the unit weight of rice husk is about 105 kg/m3. The use of rice husk in concrete at proportions ranging from 15 percent to 30 percent of aggregate (sand) has been discussed and the water cement ratio is 0.5. The rice husk concrete was found to be workable with a slump value of over 100mm. The incorporation of rice husk in concrete resulted in increase water demand and increased strength. Finally, the concrete boat succeeded to pass the floating waterproof qualifications and attend the remote control tests. The buoyancy is equal to 33.52 N and her waterline, where the hull of a boat meets the surface of the water, is approximately 6 cm. The remote control tests were held in 3 consecutive items, first item for speed tests, second item for maneuver tests, and third item for 30 minute field test remote control driving.

In this study, two types of connecting method were suggested for modularized internally confined hollow reinforced concrete (ICH RC) beams. To evaluate their performances, bending tests were carried out with a single-body specimen and two modular specimens. The two modular specimens have different connections which are distinguished with the shapes of sheath tube and the existence of connecting steel plates. The four points loading tests were performed to investigate the behavior of the modular specimens and their failure patterns. The test results showed that modular specimens have lower strengths than the single-body specimen in the elastic region, but the modular specimens finally exerted almost equal strengths to the single-body specimen at the plastic region. The maximum loads of the modular specimens were measured as 90%~95% of the single body specimen. Those experimental results are supposed by the discontinuity of the concrete at the joint and the fracture of the reinforced coupler. If these defects are reinforced, a modular ICH RC structure may show similar behavior to a single-body ICH RC structure.

: This study explores the structural behavior of module joints in floating concrete structures subjected to shear. Crack patterns, shear behavior and shear capacity of shear keys in joints of concrete module were investigated. Test parameters included shear key shape, or inclination of shear keys, confining stress levels and compressive strength of concrete. Test results showed that shear strength of joints increased as shear key inclination increased. Test results also showed that shear strength of concrete module joints increased with the increase of confining stress levels. The equation for predicting shear strength of joints was suggested, which was based on the test results. Shear strength prediction by using the equation suggested in this study showed good agreement with test results.
