Disclosed are a high-performance expansion cement clinker, a manufacturing method of the cement clinker, a series concrete expansion agent and a manufacturing method of the concrete expansion agent. The high-performance expansion cement clinker is made as follows: firstly, 50-90 wt% of limestone, 1-20 wt% of bauxite, 5-30 wt% of gypsum and 1-5 wt% of iron powder are grinded together into raw meal, then the raw meal is calcined at 1250-1400 DEG C in a rotary kiln, a tunnel kiln or a roller kiln to get the cement clinker. The cement clinker is milled alone or in combination with sulfur calcium aluminate cement clinker, calcium aluminate cement clinker, anhydrite, calcined gangue, alunite, calcined kaolin and hydration heat inhibiting additives until the specific surface area reaches 200-400m2/kg, so as to get the series concrete expansion agent. The high-performance expansion cement clinker disclosed in the invention is calcium hydroxide-hydrated calcium aluminate sulfate double-expansion source expansion clinker, which is fast in expansion rate and high in expansion efficiency and uses less bauxite of scarce resources; besides, the calcination temperature is low to avoid calcium oxide dead burning, so the preparation is safe and reliable.
