Abstract
This study investigates influence on concrete adding beverage or detergent, by work man's mistakes during concrete placement in field. Overall, concrete adding beverage or detergent does not affect slump and air content, compared with control concrete. However concrete adding detergent resulted in significantly higher air content, due to inter facial activation ingredient. For the properties of setting time, concrete adding lactic acid beverage indicated the longest retarding properties, next was coffee and soft drink in order. Compressive strength of concrete, which retarded setting time. exhibited slightly improved value at 7 and 28 days respectively, while that of concrete adding detergent significantly decreased, due to higher air content.
