Abstract

Resumen El objetivo del presente trabajo, busca conocer el posible aprovechamiento de residuos organicos, como es la cascara de almendra, como sustitucion de una parte de la fraccion granulometrica del arido grueso para la fabricacion de hormigones convencionales. Para ello, primero, caracterizamos los materiales de variables, arido y cascara de almendra. Posteriormente, fabricamos las probetas de hormigon con distintas sustituciones (10%, 20% y 30%) de cascara de almendra sobre la fraccion gruesa del arido y procedemos a la realizacion de los ensayos marcados por las normas UNE, evaluando su comportamiento a compresion, traccion, flexion, penetracion de agua, absorcion de agua, hielo y deshielo y termico. Abstract The present work seeks to know the possible use of organic waste, as is the almond shell, as a substitution of a part of the granulometric fraction of coarse aggregate for the manufacture of conventional concretes. For this, first, we characterize the materials of variables, arid and almond shell. Subsequently, we manufacture the concrete specimens with different substitutions (10%, 20% and 30%) of almond shell on the coarse fraction of the aggregate and proceed to carry out the tests marked by the UNE standards, evaluating their behavior at compression, traction, bending, water penetration, water absorption, ice and thaw and thermal.
利用有机废物(杏仁壳)替代传统混凝土生产中的粗骨料=收集有机废物(杏仁壳)替代传统混凝土生产中的粗骨料
本研究的目的是评估在西班牙和葡萄牙使用的两种不同的方法,并评估在西班牙使用的两种方法之间的差异。为此,我们首先对可变材料、干旱和杏仁壳进行了表征。之后,我们构建的试样hormigon不同取代(10%、20%和30%)杏仁cascara关于粗fraccion arido并试验realizacion键连接标准,评估其行为compresion traccion、flexion penetracion水、冰和水,absorcion解冻和termico。摘要本研究试图了解有机废物(如杏仁壳)可能用于制造传统混凝土的部分粗集料颗粒。= =地理= =根据美国人口普查,该镇的土地面积为。随后,我们其他的混凝土不同substitutions标本with(10%、20%和30%)almond和shell on the coarse fraction of the aggregate and proceed to carry out the tests marked by the连接标准,评价其behavior at compression traction、bending water penetration, water吸收,ice and thaw and thermal。
