Research this project invents for design and build the water turbine produce the electricity by set up the equipment produces the electric current from water energy flows from the nature which be new choice for Thailand in using energy pays back. then born the idea in energy water lead flows in the tide comes to use is born the advantage The water turbine has produced the electricity that does designing and establish to compose 3 part importance be the part of water buoy water turbine part is the pin wheel that is made of the iron each have a draught 90 centimeter group part carries round which compose the gearwheel yes carry round and a transmitting belt carry round . From pin wheel test produces the electric current that establishes to induce float in a river already record seek feeling numb fire efficiency reaches to open 12 DC good and use inverter to 220 v.

This research presents a study of the compressive strength chloride penetration and resistance to corrosion of concrete containing bottom ash. Fine and coarse aggregate is partially replaced with bottom ash 25 50 75 and 100% by weight of the aggregate. The results show that the compressive strength and low chloride penetration of concrete improves substantially with partial replacement of aggregate with bottom ash. Concrete mix cement containing 25 and 50% of bottom ash can be used to make coarse aggregate. In addition Concrete mix cement containing 100% of bottom ash can be used to make fine aggregate. The use of bottom ash produces concrete mix with good compressive strength and resistance to chloride and corrosion.
