Abstract： A new forming device for imitating granite concrete curb was developed, which focused on solving the problems of long forming time, production efficiency and poor appearance quality in the original forming process. The production verification shows that the initial structural strength of the new device product is 2 min, the compressive strength of the product can reach more than 90% of the design strength in 7d curing period, and the production efficiency is similar to that of the original dry process. Compared with the original wet process, the production efficiency is greatly improved, the production cycle is shortened, the occupied site is reduced, and the production cost is reduced. The compressive strength of the new device product reaches 55 MPa, the compactness reaches 2 300 kg/m3, which is better than the original process. The physical properties of the process products have been greatly improved, and the appearance quality of the new device products is smooth, which avoids the shortcomings of rough and hollow appearance of the original dry forming process products.
