The invention relates to a dynamic method for determining the formation of a Winsor III microemulsion system, the method comprising the steps of: providing a mixture of an aqueous medium and a hydrocarbon medium in a chamber; continuously altering the concentration of at least one component in the mixture, while the ratio of the aqueous medium to the hydrocarbon medium remains constant and while stirring the mixture; and continuously measuring at least one physicochemical property of the mixture. The invention further relates to a device for determining the formation of a Winsor III microemulsion system.

A method of measuring the viscosity of a resin in a bottom-up additive manufacturing apparatus, includes the steps of: (a) providing an additive manufacturing apparatus including a build platform and a light transmissive window, said build platform and said window defining a build region there between, with said window carrying a resin; (b) advancing said build platform and said window towards one another until said build platform contacts said resin; (c) detecting the force exerted on said build platform by said resin; and (d) generating in a processor a viscosity measure of said resin from said detected force.

The present invention relates to a quantitative evaluation method for concrete workability based on bottom resistance, including the following steps: step 1, carrying out a test for bottom resistance of fresh concrete; step 2, drawing a curve of inserting velocity of steel sheet over time; and step 3, quantitatively evaluating a concrete workability based on conditions of the bottom resistance. This method can quantitatively characterize the sinking condition of aggregate of the fresh concrete by effectively carrying out the test for bottom resistance of fresh concrete, calculating the inserting velocity of concrete and drawing the curves of displacement and velocity over time, so as to achieve the quantitative evaluation for concrete workability and overcome the defects of conventional methods that it is difficult to quantitatively characterize the segregation degree of concrete.

Provided are a physical property measurement method, a physical property measurement device, and a probe that can simply measure physical properties of a surface layer portion of an object. A physical property measurement method includes a step of bringing a probe into contact with a surface layer portion of a liquid or gel-like object and maintaining a contact state, a step of measuring a height of the object rising along the probe in contact with the object, and a step of calculating viscous properties or elastic properties of the surface layer portion of the object using the measured height of the object rising along the probe.
