Stamped Concrete for Imprinted Flooring Materials

The preparation of concrete is a stage in concrete engineering. The properties of pervious concrete mixtures significantly influence the performance of hardened concrete, and the mixing method is closely related to the properties of fresh concrete. Pervious concrete differs greatly from ordinary concrete in terms of material composition, hardened structure, and performance, hence its preparation methods, molding techniques, and curing methods are substantially different. During the preparation and molding process, it is essential to ensure a certain level of porosity while meeting hardness requirements. Therefore, appropriate mixing techniques must be employed to ensure that the pervious concrete mixture evenly coats the aggregates, and the paste must have suitable cohesion. Force vibration molding methods should not be used to avoid separation of paste and aggregates, which could lead to clogging of the lower pores and loss of permeability. Due to its porous structure, pervious concrete loses water quickly and experiences significant loss in workability over a short period. The impact of curing methods on its performance also differs greatly from that of ordinary concrete.
