In this report, concrete blocks for masonry are manufactured and tested, partially replacing the cement required for their manufacture with three types of pozzolan existing in the Antofagasta Region: fly ash, volcanic ash and chuzca. The purpose of this research is to try to reduce the use of cement and therefore reduce the pollution generated by its manufacture, as well as to give practical use to polluting industrial waste (fly ash produced by coal combustion in thermoelectric companies), or to materials that have been deposited naturally (volcanic ash and chuzca). All of the above allows, i...
In this report, concrete blocks for masonry are manufactured and tested, partially replacing the cement required for their manufacture with three types of pozzolan existing in the Antofagasta Region: fly ash, volcanic ash and chuzca. The purpose of this research is to try to reduce the use of cement and therefore reduce the pollution generated by its manufacture, as well as to give practical use to polluting industrial waste (fly ash produced by coal combustion in thermoelectric companies), or to materials that have been deposited naturally (volcanic ash and chuzca). All of the above allows, in addition to the environmental benefit, a reduction in the costs of the construction of masonry blocks, widely used in the Northern Zone of our country. For the research, a type of standard block is produced with 100% of the required cement, taken as a reference, and three types of blocks with different percentages of replacement of the cement by the pozzolanic additions mentioned.
