Concrete mould curing for pre-stressed units
Our patented technology lends itself very well to concrete curing applications, especially where accelerated initial curing is required. The most important applications are pre-stressed units, such as lintels, T-beams, slabs, hollow-core panels and railway sleepers. In cold weather, these can take several days to reach the required strength for de-moulding, so heat is applied to provide a 24-hour production cycle.
The heating systems can also be used to accelerate curing of other concrete moulds, using bespoke heating and insulation panels.
Traditional heating methods include steam and kerosene burners. However, these techniques are extremely energy inefficient and are not environmentally friendly or safe. In addition, they are difficult to control and may result in lower long-term strength or micro-cracking of the concrete units.
The Limpet Heating concrete curing system overcomes these issues in a number of ways, most notably using a fraction of the energy.
Our concrete curing systems generally consist of three main elements:
In a typical mould there may be more than one ‘control loop’ (typically controlling a ‘zone’ or channel in the mould), each of which incorporates a very accurate temperature sensor that feeds back the temperature information to the MegaLimpet, which then turns the heating on and off, depending upon the ramp rate or the set temperature.
