The amount of water (E) used may be appropriately adjusted in consideration of the amount of water contained in the synthetic resin emulsion and the amount of water absorbed by the aggregate (C). For example, the amount of water absorbed by the aggregate (C) is preferably measured in advance, and the amount of water used is preferably such that the whole water (including water in the synthetic resin emulsion) does not significantly flow out of the mold. Assuming that an appropriate amount of water is used based on the water absorption of the aggregate (C), the aggregate (C)
