The utility model belongs to the technical field of concrete admixture precipitation prevention, and solves the problems that a water reducing agent is not stirred in advance, precipitation is easy to generate, and the quality of concrete is influenced. According to the concrete water reducing agent pre-stirring control circuit, a coil of a circulating pump alternating current contactor KM1, a power-on delay type normally-closed contact of a time relay KT, an auxiliary normally-closed contact of an air compressor alternating current contactor KM2 and a starting switch SB1 are connected in series to form a first branch circuit; a coil of the time relay KT is connected with an auxiliary normally open contact of the circulating pump alternating current contactor KM1 in series to form a second branch circuit, and a power-on delay type normally open contact of the time relay KT is connected with an auxiliary normally open contact of the air compressor alternating current contactor KM2 in parallel and then is conne
