Sonocrete reduces the reliance on fossil fuels in concrete production and paves the way for an increased application of low-CO2 cements.1,2
The cement and concrete industry creates up to 8% of worldwide man-made CO2 emissions.3 Sonocrete reduces the reliance on fossil fuels in concrete production and paves the way for an increased application of low-CO2 cements.

Heat energy required to set concrete to required compressive strengths can be replaced by the sonocrete process without loss in performance.

In addition to the reduction in energy required to achieve similar compressive strengths Sonocrete allows concrete manufacturers to utilise renewable energy to power the Sonocrete process.

High production rates are the economic target in precast concrete production. This is achieved by using:

  1. Unblended Portland cement with high fineness (high embedded grinding energy) and
  2. High cement content in concrete. Thus the CO2 footprint of typical precast concretes is high.

Energy Consumption1,2

The chart opposite compares the energy consumption required to set concrete. The dotted line represents the theoretical calculation of a single heating of 20K of a concrete with the heat capacity of 1.06 kJ/kg*K

Compressive strengths after heat treatment and sonication are in a similar range after 12 hours.
