This paper is a presentation of compressive strength testresults on plastered straw bale block. Guinea corn – straw fiber were baled and plastered with mortar into straw bale blocks of fibers with an average of 6mm thickness, 11.2% moisture content, and baled at a density of range between 0.161-0.190 kg/ mm 2. The fiber blocks were subjected to ver...

... Figure 3.6shown before, the failure mode of the plastered bale tested was clearly failed as a result of the splitting cracks of plaster which is known as global buckling, that is typical well built wall behavior when eccentrically loaded. ...
Context 2
... straw bales' densities as it presented in the Figure3.1 showing that, no standard density can be adopted because of the unused of baling machine but its variation in density, significantly predicted the effect of water absorption as well as compressive strength, example the group of A30 and A32 samples was found to have the least density as well as the compressive strength. ...

Pressed condensation is a key process before the reclamation of loose corn straws. In this study, the effects of stabilization time on the relaxation density and dimensional stability of corn straws were studied firstly, and then the stabilization time was determined to be 60 s by comprehensively considering the compression effect, energy consumpti...

El objetivo de esta investigación es determinar las características físico-mecánicas de los fardos de paja producidos en Ecuador, para definir su posible uso en la construcción de viviendas sismo resistentes. Para lo cual, se utilizaron métodos experimentales propuestos por Vardy (2006) en los fardos, variando su posición para pruebas de carga en plano y canto.
Obteniendo así el módulo de elasticidad del fardo desnudo y revocado en sus caras, con un mortero en base de cal, cemento y fibras naturales previamente diseñado. Se determinó que el máximo módulo de elasticidad del fardo revocado varía entre 12,98 y 18,67 MPa. Estos valores fueron utilizados para realizar el modelamiento estructural de una vivienda tipo, mediante el uso de un software, para proponer una solución habitacional que fomente el uso del fardo de paja producido en Ecuador para la construcción de viviendas sismo-resistentes. Del análisis de este modelo se concluye que las derivas inelásticas máximas de la estructura propuesta, con mampostería portante realizada con los fardos de paja, son menores al 2 %, con un revoco de espesor de entre 3 y 4 cm, concluyendo que las respuestas estructurales obtenidas cumplen con lo establecido para viviendas
