Abstract

Provided is a geopolymer composition manufacturing method that does not cause deterioration of strength development even in the case in which an alkaline solution added in a manufacturing step is replaced with an alkaline powder and water. The method is configured: so as to include an alkaline-powder pulverizing step in which all or a portion of an aggregate is introduced into a mixer first, water employing a portion or all of kneading water as a primary water volume is added to and mixed with the aggregate such that the water is uniformly held at a surface of the aggregate in the mixer, and an alkaline powder is added to and mixed in the mixer to pulverize the alkaline powder; and so that a geopolymer composition is generated by adding and mixing remainder materials containing an active filler after the alkaline-powder pulverizing step. Therefore, the alkaline powder is finely pulverized in the alkaline-powder pulverizing step, the specific surface area thereof is increased, and thus, it is possible to increase the rate at which the alkaline powder dissolves in water. Accordingly, it is possible to increase the chemical reaction rate.

Abstract

In a detection method of a loading anomaly, relationship between a steering control value of a vehicle and a proper turning radius for the steering control value is constructed as a control map. An actual turning radius of the vehicle is calculated by using a self-location detection function of the vehicle. A difference between the proper turning radius and the actual turning radius is calculated by using the control map. It is determined that a loading anomaly of a cargo loaded on the vehicle has occurred when the difference lies outside a predetermined first reference range.
