Abstract

Concrete is produced so that the compsn. of the mixture is determined by the humidity rate of the sand which equals at least that of a stored sand. Mixing of the ingredients includes the determination of the humidity of the sand to be used, providing water to supplement the actual content to that required whilst also weighing the sand and the water. Suitable equipemt is described.
