The invention relates to a polycarboxylate composite water reducing agent suitable for low-cementitious material concrete and a preparation method thereof. The polycarboxylate composite water reducing agent suitable for the low-cementitious material concrete is characterized by comprising the following components in percentage by mass: 15 to 25 percent of polycarboxylic high-performance water reducing agent, 1 to 5 percent of retarder, 0 to 0.10 percent of defoaming agent, 0.01 to 0.3 percent of air entraining agent, 0.3 to 0.5 percent of preservative and the balance of water, wherein the mass solid content of the polycarboxylic high-performance water reducing agent is 40 percent. The polycarboxylate composite water reducing agent is applied to the concrete, and has the water reducing rate over 20 percent by comparing the concrete with reference concrete; and the prepared concrete has the advantages of good workability, no dissociation or bleeding, and good freezing resistance and infiltration resistance, and can be used for preparing concrete with various strength grades between C20 and C40.
