| Abstract Scope |
Processes of construction and building materials industry have become the results of the quarry exploitation activities. This is associated with inefficient processes due to its large consumption of resources for the sandstones washing which generates waste without use, ie, Sludge and soft clay as principal products. In this work, a waste for a Colombian quarry is stabilized by the use of mineral charges of SiO2 with variable particle sizes, in addition to Ca(OH)2 and Na(OH) with different molar ratios. A statistical design of experiments with a surface response is used, looking for a suitable composition so can obtain a material with a load-bearing capacity and dimensional stability. The use of this methodology is proposed for the stabilization and the use of this material as the raw material for the production of prefabricated; blocks or masonry elements, achieving more sustainable processes in the production chain of the mining and construction industry. |
