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.

SofoNic: A committed team (part 1) http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/161-sofonic-a-committed-team-part-1 http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/161-sofonic-a-committed-team-part-1 Oxana Delgadillo & Livio González   

SofoNIC, as a team, feels committed to one of the most important tasks in the history of mankind: development and use of the land. We don't need a deep study to realize that one of the main pillars in human development is knowing how to make use of the existing natural resources in order to survive. From primitive times our ancestors based their social development on different rural activities, such as hunting, food gathering and later, agriculture.

MicroConcrete Roof tiles in post-Mitch houses in Honduras http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/162-microconcrete-roof-tiles-in-post-mitch-houses-in-honduras http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/162-microconcrete-roof-tiles-in-post-mitch-houses-in-honduras Víctor Martínez - Honduras   

Honduras, a country severely devastated by Hurricane Mitch, leaving 35,000 homeless families and other 50,000 greatly affected with damages between 10 to 50%, received aid from a multitude of friendly countries which made great efforts in order to help solve the problems of habitation generated by this climatic phenomenon.

MCR equipment with Battery or Transformer ? http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/163-mcr-equipment-with-battery-or-transformer http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/163-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.

Colombian decision-maker receives MCR overview in Riobamba http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/164-colombian-decision-maker-receives-mcr-overview-in-riobamba http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/164-colombian-decision-maker-receives-mcr-overview-in-riobamba introducing MCR as a means of improving the quality of construction in Colombia through these organization, Pedro and EcoSur officers talked over future plans to achieve this goal. They worked intensively to have a good overview of the whole process of producing tiles, and how to lay them on the roof. ]]> paulmoreno@gmail.com (Administrator) August 2003 Thu, 06 Jan 2005 14:56:35 +0000 News - August 2003 http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/165-news-august-2003 http://english.ecosur.org/index.php/past-editions-e-magazine-285/47-august-2003/165-news-august-2003 CP40 blocks now produced in Nigeria
The first CP40 block workshop in Nigeria (the first in the entire African continent) is in production. Sergio Betancourt of CIDEM ensured its installation and quality of the blocks during a second mission for GECOTEC, whereby a local organization in the area of Abuja decided to produce this alternative cement. Because of the astronomical price of lime they decided to use puzzolana alone as mineral admixture, instead of mixing it with lime. This works extremely well. The puzzolana tests were carried out at the University of Kassel in Germany after the first mission to assess the feasibility of CP40 production.

MCR roof in Angola
On their travels throughout the world, colleagues of EcoSouth come across MCR roofs in surprising places. Recently Ivan Labra was in Sumba, a coastal town south of Luanda, in Kwanza Sul Province in Angola. He discovered that Caritas had produced the tiles and roofed its buildings with MCR.

Professors
The construction faculty at the University of Santa Clara, Cuba, has a joint investigation project with the University of Lausanne, Switzerland. They are studying and documenting the new style management based on popular participation that has been implemented by the CIDEM housing projects in the province. Five Cuban professors were in Lausanne at the beginning of June for an interchange about progress of their joint work.
