SONO
Lab-quality concrete testing on site – for your compliance
With the SONO, the water content of fresh concrete can be quickly and precisely determined on site. The device is based on the innovative TRIME® Radar technology and supports simple quality controlprocedures on the jobsite.
An excessively high water content in the fresh concrete leads to capillary pores, whereby water can penetrate deep into the concrete. The consequences are increased frost sensitivity with the risk of spalling and reduced protection of the reinforcing steel against corrosion.
If there is too little water in the fresh concrete, not all cement grains are sufficiently supplied with water. Unhydrated cement can swell when water enters later and lead to cracks in the concrete and thus also to strength losses.
With 4 to 5 measurements, you can obtain reliable information on the water content in fresh concrete with the SONO within 1 to 2 minutes. You can thus quickly calculate the w/c ratio.
Compared to the previously common measurement of the water content in the Darr method (approx. 30 min), the PERI SONO WZ analyzer ensures time savings on the construction site.
The w/c ratio determines the proportion of cement gel, gel, capillary and air voids in the hardened concrete. Capillary and air voids in the hardened concrete have a great influence on the load-bearing capacity and durability of the concrete.
In addition to the physical properties, the water content of the fresh concrete also influences the visual concrete result.
SONO saves valuable time in determining the water-cement ratio not only on the construction site, but also in the laboratory.
Using innovative TRIME® radar technology, reliable measurement results of the water content in fresh concrete can be obtained quickly.
TRIME® radar technology
SONO works on the basis of radar technology with state-of-the-art TRIME®TDR technology (Time-DomainReflectometry). This novel technology has been validated in many years of cooperation with several scientific institutions.
In the so-called time-of-flight measurement, a radar pulse is used to determine the volumetric water content. The basic technology is successfully used for a wide variety of moisture measurements. For moisture measurement in fresh concrete, the method was further developed accordingly. The special probe and the associated handheld meter now offer a simple solution for reliable results on the construction site.
