“…Se encontró que la resistencia a la compresión está por encima del valor mínimo necesario (3.5 MPa) exigido por la norma técnica colombiana ntc 4205. Con respecto al espécimen preparado a partir de la adición individual de vidrio m2 se encuentra una resistencia 2.6 veces mayor (5.27 MPa) a la muestra de control, en línea con los reportes previos de Akinyele y colaboradores [18], quienes reportaron una mejora en la resistencia a la compresión fuertemente dependiente de la incorporación y del contenido de residuos de vidrio en la preparación de ladrillos de arcilla con adiciones de vidrio. Asimismo, para el material preparado con adición individual de agregados, se observó una mejora mucho más marcada en la resistencia a la compresión, alcanzando una resistencia 9 veces mayor (18.08 MPa) a la muestra de control.…”

“…Con respecto a la densidad de los especímenes, se encontró una relación inversa con el porcentaje de plástico; este comportamiento fue atribuido al peso ligero del pet. Para resolver el problema asociado con la desintegración de los ladrillos, Akinyele y colaboradores [18] investigaron la adición de residuos de vidrio en porcentajes de 1 %, 2 %, 3 %, 4 %, y 5 % en la preparación de ladrillos. Los autores reportaron que este material evita la desintegración de los especímenes durante su proceso de elaboración.…”

El uso de desechos no biodegradables como el vidrio y el plástico en la industria de la construcción ha recibido atención significativa para un medio ambiente más limpio. Este trabajo presenta un estudio de las propiedades mecánicas de ladrillos que contienen agregados, vidrio y pellets de tereftalato de polietileno. Los ladrillos se fundieron a 240 °C durante 3 horas y se enfriaron por convección natural. Los resultados mostraron que un aumento en el contenido de vidrio y agregados genera un incremento en la densidad, que es superior en las muestras con mayor contenido de agregados. La misma tendencia se observó en la resistencia a la compresión: la muestra con mayor contenido de agregados mostró una mejora del 243 % comparada con la referencia (preparada solo con plástico). Los resultados indicaron que las emisiones de dióxido de carbono disminuyeron alrededor del 30 % en las muestras preparadas, en comparación con los ladrillos tradicionales. Se espera que el uso de residuos de plástico y vidrio en la producción de ladrillos se convierta en una ruta para su valorización.

“…The highest strength of 11 MPa was obtained with a (4 + 5)% mixture and was more than 10 MPa (threshold for first-class bricks). The second-class types had a minimum compressive strength of 7 MPa and water absorption of 25% [39]. Except for C45, all other bricks were second-class bricks suitable for external and internal walls without plastering.…”

Manufacturing of Clayey Bricks by Synergistic Use of Waste Brick and Ceramic Powders as Partial Replacement of Clay

et al. 2021

Clay bricks are extensively used as building material worldwide. Natural soil deposits are in constant reduction due to the frequent use of clay to manufacture bricks. About 1600 billion bricks are produced annually by the consumption of millions of tons of natural resources. The prime focus of this study is to assess the feasibility of using a composite mixture of waste brick powder (WBP) and waste ceramic powder (WCP) as a replacement for depleting natural resource “clay” in brick manufacturing. Based upon the previous studies, the replacement levels were kept as (4 + 5)%, (8 + 10)%, and (12 + 15)% of WCP and WBP, respectively. The brick specimens were evaluated in terms of compressive strength, modulus of rupture, density, water absorption, efflorescence, apparent porosity, resistance to chemical attack and sulfate attack, and freeze-thaw resistance. The study reveals that about 27% of clay can be replaced with ceramic waste powder and waste brick powder, which can preserve a massive amount of natural clay without compromising the quality of the bricks.

“…Based on literature review, several pozzolanic waste materials have been utilized as cement replacement in block/brick production such as sewage sludge ash, fly ash, metakaolin, waste clay bricks, ceramic and tile wastes, crushed waste calcined clay bricks, ceramic sludge to mention a few [ 6 , 7 , 8 , 9 , 10 , 11 ]. In addition, several waste materials have been utilized as aggregates in block/brick production such as quarry dust, waste crushed glass, polyethylene wastes and waste tyre rubber, construction and demolition wastes and waste tyre rubbers [ 12 , 13 , 14 , 15 , 16 , 17 ]. It was observed that cement reduction and replacement of natural aggregates in solid/hollow block/brick production is possible without sacrificing their quality as displayed in Figure 1 .…”

Hollow sandcrete blocks constitute more than 90% of residential building construction in developing countries especially in West Africa. Over-reliance on dredged river sands and conventional ordinary Portland cement (OPC) contributes to environmental degradation and post-construction problems such as swelling and shrinkage-induced cracks prevalent in construction projects. The study investigates potential utilization of locally available materials such as laterite, calcite and calcined clay as ternary and quaternary blends to replace cement and quarry dust as 100% replacement of river sand with the aid of Taguchi-Response surface methodology approach. Optimum ternary blend of 24% calcined clay +1% calcite +75% OPC is recommended to achieve volume stability, higher compressive strength and higher flexural load capacity. Alternatively, ternary blends of 24% calcite +4% calcined clay +72% OPC can also be utilized. The improved mechanical properties were attributed to the Na- and Ca-rich aluminosilicates provided by the blended cements. Successful utilization of ternary and quaternary blended cements to produce stronger, durable and eco-friendly sandcrete blocks depends on utilization of high binder-to-aggregate ratio, optimal combination of the constituents, appropriate water-cement ratio and curing/production method. Partial and 100% replacement of river sand with granite dust is possible and contributes to reduction of environmental problems caused by river dredging as well as cleaner, ecofriendly construction. Ternary and quaternary blended cements is recommended to avert post-construction problems such as swelling and shrinkage-induced cracks prevalent in construction projects.
