High quality MCR in Bangladesh - the force of fidelity

Nolasco Ruiz   

Three basic points should be fulfilled in the manufacture of Micro-Concrete tiles (MCR) in order to have an efficient, steady and good quality production.

  • In the first place, vibrating machine and moulds should be accurate, clean and well-maintained
  • In the second place, materials should conform to established standards of quality
  • Third and most important, the person himself. Even with proper equipment and materials, if the workers are not competent, the quality of tiles will be inadequate and the tiles will be useless.

MCR equipment with Battery or Transformer ?

Kurt Rhyner   

Most MCR equipments use a 12 Volt motor to vibrate the screed. In many workshops they connect them to the grid using a transformer. However, the deficient quality of the transformer is often the reason for bad vibration or worse, for overheating and damaging the motor. A transformer has to provide an output of at least 10 Amps in order to guarantee a reliable flow of electricity, and it has to have an equalizer to avoid fluctuations in the current it provides to the motor.

EcoMateriales: Teja de MicroConcreto y Paneles de FerroCemento

The EcoSur network presents a short professional video on two major technologies, the Ferrocement panels and the Micro Concrete Roofing Tiles. Filmed in Nicaragua and Salvador, it shows production and application and gives a summary overview of those two materials that have a relatively small ecological footprint and have widely proven to be sustainable in the three classical dimensions ecology, economy and social acceptance.
