In order to reduce the amount of an organism attractant substance remaining inside concrete that tends be used wastefully and also to allow the organism attractant substance to effectively flow out gradually in a long period of time, an environmentally active, preserving and repairing-use concrete block is provided in which the air content and flowability of the concrete are increased, and the congregating and growing effects for fishes and shellfishes and the adhering and growing effects for algae are maintained so that a high attractant effect by odor of the organism attractant substance is obtained. An environmentally active preserving and repairing-use concrete block is provided with at least three or more legs, and in this structure the environmentally active preserving and repairing-use concrete block is formed by using an environmentally active preserving and repairing-use concrete having high air content and high flowability formed by kneading an organism attractant substance having a specific odor therein.

A blowby gas circulation system for an engine having a crankcase and an intake system includes an oil tank which is independent of the crankcase, a first breather chamber and second breather chamber which are integrally provided with the crankcase. The oil tank supplies engine oil reserved therein to the crankcase and introduces a first gas-liquid mixture generated in the crankcase. The first gas-liquid mixture is separated into a second gas-liquid mixture and engine oil in the oil tank. Then, the second gas-liquid mixture is sent to a first breather chamber, being separated into a third gas-liquid mixture and engine oil. The third gas-liquid mixture is sent to a second breather chamber in which the third gas-liquid mixture is separated into blowby gas and engine oil. The blowby gas is sucked into the intake system and the engine oil is returned to the crankcase.
