Increasing the fluidity of the RMC industry's distribution
Now we need to improve the cooperation and make a deeper relationship with the main suppliers of the RMC factories, admixture trading companies. They're able to reach every concrete plant in Japan. They visit the plants daily, understand the needs and so become aware of what products may become sellable. For example, chemical admixtures.
