peer agreement (net): +1flowable fill Explanation: ...at least according to the glossary: http://www.proz.com/?sp=h&id=70720&keyword=hormig�n de limpieza Flowable fill is commonly used as an economical fill or backfill in road construction. It is usually a mixture of coal fly ash, water, a coarse aggregate (such as sand), and portland cement. Flowable fill can take the place of concrete, compacted soils, or sand commonly used to fill around pipes or void areas. Other applications include filling in bridge abutments, foundation subbases, or abandoned man holes and wells. Flowable fill can help put significant quantities of coal fly ash and spent foundry sand, two types of recovered materials, back to good use. http://www.epa.gov/cpg/products/flow-fil.htm -------------------------------------------------- Note added at 28 mins (2004-06-04 09:55:42 GMT) -------------------------------------------------- Well, after looking a little more, I found the following: mud slab - hormigón de limpieza – capa de hormigón de 2 a 6 in. (50 a 150 mm) de espesor entre un piso o zapata de hormigón estructural y un suelo blando y/o húmedo; también se denomina mud mat. http://www.inti.gov.ar/cirsoc/complementarias/Terminologiaho... From the Penguin Dictionary of Civil Engineering: mud slab, mud mat - ACI\'s terms for the UK\'s blinding concrete. (ACI = American Concrete Institute). blinding mat, mattress, sealing coat (mudsill, mudmat USA) A layer of lean concrete usually 5-10 cm thick, put down on soil such as wet clay to seal it and provide a clean bed for laying reinforcement. Blinding concrete A layer of dry lean concrete about 50mm thick covering the bottom of an excavation, either over hardcore or directly on the foundation, to seal the underlying material and prevent mud from dirtying the reinforcement bars or intruding into the concrete of footings http://www.dreamghar.com/b1dic.htm |

peer agreement (net): +1underconcrete Explanation: ADVANTAGES * Control of cracking Significant reduction of cracking due to shrinkage and mechanical loads. * Greater ductility of the concrete Increased toughness of the improved concrete to control cracking. * Improved resistance of cracked concrete Concrete with steel fibres is strengthened and becomes a more ductile material, enabling it to support a greater load when cracked. * Reduced thicknessess Smaller amount of concrete required. The absence of mesh makes it possible to achieve surfaces that are not so thick. * Greater distances between joints Fewer dilation joints. * Even distribution of the reinforcement Less plastic cracks due to shrinkage. The even distribution of the fibres allows greater control over the effects of cracking. Guarantees greater durability of the flooring or paving. * Does not require underconcreting Reduced costs. * Greater daily production capacity The ease with which it is handled and used makes it quick to apply and cuts down the work of placing reinforcements in structural elements. Its easy application means that the fibres can be placed straight into the concrete mixer for mixing or into the mixer lorry. VENTAJAS * Control de la fisuración Reducción significativa de la fisuración por retracción y por cargas mecánicas. * Mayor ductilidad del hormigón Aumento de la tenacidad del hormigón mejorado y controlando la fisuración. * Mejora la resistencia del hormigón fisurado El hormigón con las fibras de acero, se refuerza y se convierte en un material más dúctil y permite una mayor capacidad de soporte de carga en condiciones fisuradas. * Reducción de espesores Menor cantidad de hormigón. La ausencia de mallazo permite obtener superficies de menor espesor. * Mayor espaciado entre juntas Menos juntas de corte. * Distribución homogénea del refuerzo Menos fisuras plásticas por retracción. La distribución homogénea de las fibras permite mayor control en los efectos de fisuración. Garantiza una mayor duración de la solera o pavimento. * No precisa hormigón de limpieza Costes más reducidos. * Mayor capacidad diaria de producción La sencillez en su manejo y uso permiten una gran rapidez de aplicación, reducen las tareas de colocación de refuerzos en elementos estructurales. Su fácil aplicación permite colocar las fibras directamente en la hormigonera para su mezcla o dentro del camión cuba. Reference: http://www.rimsa.com/esp/construccion.htm |
