A low-toxicity concrete revetment block manufacturing method is provided to prevent the pollution of sea due to toxicity of the cement by using strong adsorption power and a great quantity of anion emitted from silicate minerals. A low-toxicity concrete revetment block manufacturing method comprises the steps of: kneading concrete by equally mixing gravels of 37~41wt.%, sand of 34~38wt.%, cement of 14~16wt.%, sericite powder of 1~2wt.%, chlorite powder of 0.5~0.7wt.%, and sewage sludge incineration ashes of 0.5~0.7wt.%, and then pouring the water of 7~9wt.%; molding a revetment block by inserting a steel frame into a mold and then injecting concrete; and completing the concrete revetment block by separating the mold after the concrete is hardened, and then curing the molded concrete for 6~8 days.
