Factibilidad del uso del Raquis de Palma Africana en mezcla con agregados de construcción para la fabricación de ladrillos ecológicos

Abstract

It was re - evaluated the rachides of the African Palm, by using it as main component in the elaboration of ecologic bricks that will be used in the branch od construction, overcoming some characteristics of the conventional bricks in resistance and weight. Fort he investigation was made physical - chemical analy ses to recognize the characteristics and the elemental composition of the residue, the physical analyses showed a content of humidity of 33,47%, a capacity of absorption of 81% and a specific weight of 0,10g. To recognize its composition was analyzed chemi cal parameters such as pH, Nitrogen, Carbon, and Silicium, which showed values of 8,35 units of pH (UPH), 0,36kg/mg, 55 ,85 kg/mg and 245 kh/mg respectively. Once it was obtanied the characterization of the filber, four different mixtures were formulated fo r the manufacturing of the bricks, the firts mixture formed by 38% of rachides, 18% of sand, 32% of clay, 32% of cement; the second mixture 41% of rachides and 50% of clay; the third mixture of rachides, 18% of sand and 5% of cement; and the fourth mixtur e formed by 58% of rachides and 34% of cement. Finally to know the mechanic and physical characteristics of the manufacture bricks, compression, flexion and humidity tests were made within the norm. It was proved thet the usage of fiber of rachides in the manufacturing of bricks for aim of construction is posible, since the physical and mechanic properties of the conventional brick improve. In addition, to the diminishing of cost production and the negative shock to the enviroment. T hat is why is recommende d to keep making mechanic proofs to the ecologic bricks whit rachides to kanow their capacity such as acustic and thermic isolators and implement a financial investment Project for the execution of a Factory of ecologic bricks of rachides.
