“…Con respecto al suelo utilizado, se observa que se tienen resultados positivos a pesar de tener un 40% de limos y arcillas (Figura 3), siendo que las recomendaciones señalan valores en torno del 30% (GATANI, 2000;AROOZ;HALWATURA, 2018). No obstante, el suelo del sector estudiando (Champa Rancho -Cochabamba) puede ser utilizado en la fabricación de ladrillos de suelo-cemento, incluso se podrían obtener mejores resultados reemplazando parte de los limos y arcillas por arena, en un porcentaje cercano al 10%.…”

“…Si bien su composición es simple, suelo con material inorgánico, arena, y estabilizante, cemento; para su elaboración se requiere una clasificación adecuada del suelo, compactación, estabilización, además de un proceso de cura y secado, lo que garantizaría mayor densidad, menor absorción de agua, mayor resistencia a la compresión, entre otras propiedades (OTI; KINUTHIA, 2012;NAGARAJ et al, 2014). Con relación al suelo a ser utilizado, se recomienda que tenga un elevado porcentaje de arena y se limita entre 20% y 30% el contenido de limos y arcillas (GATANI, 2000;AROOZ;HALWATURA, 2018).…”

La producción de ladrillos en Bolivia todavía es realizada de manera tradicional, a través de un proceso de cocción o quemado, la cual consume recursos naturales y genera impactos negativos al medio ambiente. En la literatura existen diferentes alternativas ecológicas para la fabricación de ladrillos, entre ellas se encuentran los elaborados con suelo y cemento, que no necesitan cocción y utiliza uno de los materiales más abundantes, el suelo. En este sentido, el presente trabajo tiene como objetivo evaluar la resistencia a la compresión de ladrillos de suelo-cemento a diferentes proporciones de cemento, de forma de encontrar los porcentajes más adecuados para su aplicación en la construcción. Para tal motivo fueron fabricados en total 75 ladrillos de suelo-cemento, 15 para cada porcentaje de cemento propuesto (2%, 4%, 6%, 8% y 10%), los cuales se ensayaron a los 7, 14 y 28 días para observar el aumento de la resistencia a la compresión desde su elaboración; el suelo fue seleccionado de la zona sur de la ciudad de Cochabamba, sector caracterizado por el asentamiento de ladrilleras artesanales. Los resultados muestran que, a mayor porcentaje de cemento, mayor resistencia a la compresión se presenta; los ladrillos de 8% y 10% de contenido de cemento mostraron los mejores resultados y, por tanto, su aplicabilidad para su uso en la construcción. Palabras clave: resistencia a la compresión, suelo-cemento, ladrillos ecológicos.

The focus on sustainability is at its peak in the construction industries in the last couple of decades. That includes green constructions such as rammed earth construction. Due to media exposure and carbon emission, people are undeniably turning to green and sustainable buildings. Furthermore, there is an improper management pattern of solid waste management found in developing countries, such as open burning and dumping of solid wastes. In which paper waste is not handled in a good way. There arefew places in developing countries where developing countries follow proper management of solid waste. Paper waste is present in each city because people are using it for daily life. Paper waste has fibre in them and has cellulose content. These components of paper waste are suitable for compressive strength. It has a side effect that it increases water absorbability. The reason for this research work is to reduce paper waste and reduce cement content. This paper also aims to find the durability and strength properties of rammed earth construction.

“…These materials are cement, sand, bricks, steel, wood, glass, tiles, etc. Sometimes harmful pollutants are released by building materials damaging the environment [1]. In the production of cement, there is a large magnitude of creation of CO2 gas which is hazardous to our environment [2].…”

Materials are the most important component of building construction. The demands of construction material are increasing day by day significantly. This demand is increasing the material prices and scarcity of material in construction industry. To achieve economical and eco-friendly criteria naturally occurring material is selected. Clay is a natural material and it can be available easily. This paper interprets the experimental investigation on strength of concrete using clay as a partial replacement to binder content (cement) in concrete. The replacement percentages are grouped as 0%, 10%, 20%, 30%, 40% of clay and 5% of hydrated lime with cement in each series in M25 grade of concrete. To achieve the pozzolanic property of clay hydrated lime was added. Different tests are performed to determine the optimum percentage of clay as a replacement for binder content (cement) in concrete. The Compressive strength test, split tensile strength test and flexural strength test were performed on the specimens. Total 90 cubes of size 150 mm were prepared for compressive strength test, 30 cylinders of 150 mm diameter and 300 mm height were prepared for split tensile strength test and 30 beams of size 150 mm x 150 mm x 1000 mm were prepared to carry out the flexural strength test. The results are compared to find the ideal proportion of clay as a replacement for cement. It is found that 10% replacement with 5% hydrated lime gives satisfactory results.
