    • The material under testing is irradiated with a heating beam to deform the material surface forming a protrusion on the same. At the same time a measuring beam acts on the surface so that it is reflected by the protrusion, providing a beam scattered by the protrusion curvature that is detected by a small opening as a spatial filter located closer or farther than the confocal distance. The beam transmission through the disfocal opening varies according to the protrusion curvature induced by heating. The signal transmission allows determining the magnitude of the induced dilation. Said magnitude and its dependence on the modulation frequency allow determining physical properties as the dilation coefficient or the thermal diffusion coefficient, the coating film thickness or the incident light absorption coefficient on the heating beam. Varying the wavelength of the incident radiation it is possible to determine the absorption spectrum of the sample even for very small dimension particles wherein the absorbed energy fraction is negligible.

    • Methods and devices for improved measurement of the thermal expansion and/or chemical reactivity of aggregates used in concrete and for similar substances. Aggregate is placed into the chamber of a metallic container having an enlarged opening. The aggregate is placed in a water bath, and a tightly sealable lid is placed onto the container. The lid carries a linear variable differential transducer (LVDT). A thermocouple for sensing temperature is also retourned within the lid so that a sensor on the thermocouple contacts the water bath when the lid is secured onto the container. The LVDT is operationally interconnected with a storage or recording device. In a preferred construction the lid retains a tower member having a float that is freely moveably mounted upon a guide rod. Movement of the float is indicative of a volumetric change in the aggregate and water. In operation, the dilatometer device is used to determine the information relating to the amount of expansion or contraction of the aggregate in response to thermal changes. In addition, the devices and methods of the present invention are useful for determining the degree of reactivity of the aggregate. The degree of volumetric change for the aggregate alone may be determined using equations that isolate and remove the expansion quotient of the water.
