Abstract: The present invention relates to a high visibility concrete composition comprising 12-19 wt% of white Portland cement, 4-9 wt% of water, 30-45 wt% of a fine aggregate, and 33-48 wt% of a coarse aggregate. The high visibility concrete composition further includes 0.001-0.03 part by weight of an admixture based on white Portland cement weight and uses the white Portland cement having 85-96 of whiteness. Limiting the whiteness of the white Portland cement ensures visibility of a structure manufactured by the concrete composition. The concrete composition using the white Portland cement usually has a problem of poor visibility after curing in rainy weather or at night, especially. To solve the problem, the present invention ensures visibility of a concrete composition and hardness such as compression strength by using the white Portland cement having 85 or more of whiteness. The white Portland cement is mixed with one among slag micropowder, fly ash, silica fume, or waste glass. A mixing ratio of the white Portland cement and one among the slag micropowder, the flay ash, the silica fume and the waste glass is 95:5-50:50.

Title: Angle Control Apparatus With Shock Absorbing Structure For Outboard Motor Of Ship

Abstract: The present invention relates to an angle control apparatus for a ship propeller having a buffer structure for an impact applied to a propeller housing by rocks in a ship propeller which rotates a propeller (2) disposed on an outboard output shaft of an engine (1) installed on the stem, and has an angle control cylinder (4) having one end fixed to the stem and the other end connected to the propeller housing (3) so that the propeller (2) is disposed under the water for navigation or lifted up for anchorage. The buffer structure includes a rod clamp (50) which is provided at one end of a piston rod (30) to engage with or release from the same, and of which an outer side is coupled to a piston (20) such that the piston rod (30) is separated from the piston (20) by impact force applied to the propeller housing and then, moves into the cylinder to allow the propeller housing to rotate upward. When the propeller housing, for example, a bottom tail portion, hits rocks during navigation, the piston rod of the angle control apparatus moves while being separated from the piston by the rod clamp such that increased oil pressure causes a support plate to compress a spring to absorb the impact force, thereby preventing damage to the propeller housing, the propeller, and the angle control apparatus and thus, greatly reducing the burden of expenses for a user. The buffer structure has an engagement structure in which the rod clamp can be easily separated from the piston rod by the impact force, thereby reducing manufacturing costs.
