“…El porcentaje de fibras demostró tener gran importancia en los resultados, lo cual contradice los resultados mostrados por Hoang y Fehling [28]. Por otro lado, los resultados obtenidos en este estudio se asemejan a los alcanzados por la mayoría de los pesquisadores consultados, como por ejemplo Kahanji et al [29], Wu et al [30] y Alsalman et al [31].…”

“…WU et al [30] fabricaron una mezcla de concreto sin fibras y cinco mezclas con fibras para evaluar las propiedades estáticas y dinámicas del concreto sometido a compresión, alcanzando 98,30 y 143,6 MPa respectivamente. Alsalman et al [31] alcanzaron una resistencia a la compresión máxima de 118,6 MPa en especímenes sin fibras y sin tratamiento térmico en el curado, usando materiales comerciales locales, también trabajaron con especímenes incluyendo tratamiento térmico en el curado, alcanzando 127,38 MPa sin fibras y 157,46 MPa con fibras.…”

RESUMENSe presenta un estudio experimental para producir Ultra High Performance Fiber Reinforced Concrete (UHFPRC) incluyendo residuos industriales en la mezcla y determinar la resistencia a la compresión promedio. El estudio incluye arreglos factoriales para realizar análisis de varianza usando ANOVA. Los factores controlables fueron: (i) edad de la muestra; (ii) granulometría de la escoria; (iii) diseños de mezcla; (iv) porcentajes de fibras y (iv) tipo de curado. Los mayores valores de resistencia obtenidos fueron 138.12, 132.17, y 155.29 MPa, con sustituciones parciales de cemento por residuos industriales del 35, 25 y 26% respectivamente. Los diseños de mezcla fueron fabricados aplicando un procedimiento simple, usando en la mezcla materiales como cemento, humo de sílice, escoria de alto horno, polvo de cuarzo y arena fina producidos en Brasil. También se adiciona el superplastificante diluido en agua y las fibras, las cuales se incorporan cuando la mezcla se convierte en una densa masa plástica. Los resultados demostraron que todos los factores controlables tienen influencia significativa en la variable de respuesta y que la probabilidad de que las variaciones en la resistencia sean atribuidas al error experimental es menor al 1‰.Palabras-clave: UHPFRC, sustentable, resistencia a la compresión, ANOVA. ABSTRACTAn experimental study is presented to produce Ultra High Performance Fiber Reinforced Concrete (UHPFRC) including industrial waste in the mix, and determine the average compressive strength. The study includes factor arrangements to perform analysis of variance using ANOVA. The controllable factors were: (i) age of the sample; (ii) granulometry of the slag; (iii) mix designs; (iv) percentages of fibers and (iv) thermal treatment in curing. The highest resistance values obtained were 138.12, 132.17 and 155.29 MPa, with partial substitutions of cement by industrial waste of 35, 25 and 26% respectively. The mixing designs were manufactured using a simple procedure, using materials such as cement, silica fume, blast furnace slag, quartz powder and fine sand produced in Brazil. Also, the mixture includes the superplasticizer diluted in water and the fibers, which are incorporated when the mixture becomes a dense plastic mass. The results showed that all the controllable factors have significant influence on the response variable, and that the probability that the variations in resistance are attributed to the experimental error is less than 1 ‰.

“…In both cases, high-volume silica fume was used, which does not help much in reducing the production cost of UHPC. Alsalman et al, (2017) found that the use of finer sand increases the compressive strength when compared to natural gradation sand, however, this effect is minimal when silica fume is incorporated. In contrast, Ma et al (2004) concluded that the grain sizes of sand had no significant effect on the concrete's compressive strength.…”

“…The usage of very high amounts of cement not only affects the production costs, but also has negative effects on the heat of hydration and may cause shrinkage problems (Alsalman et al, 2017). Incorporation of supplementary cementitious materials has the potential to positively affect the durability of concrete and reduce the production cost.…”

In recent years, ultra-high-performance concrete (UHPC) has attracted interest from the research community because of its excellent physical, mechanical, and durability properties. However, due to very high production cost, its application in civil infrastructures has been thus far limited. In this context, an experimental investigation was conducted to produce lower cost UHPC utilizing locally available traditional fine aggregates. In order to obtain the maximum packing density and minimum matrix porosity, uniquely size graded manufactured fine aggregate was produced. Silica fume, industrial and natural pozzolans were used at different replacement levels of cement content. Flow properties, dimensional stability, and compressive and tensile strengths at different ages of the studied UHPCs were evaluated. More than 120 MPa compressive strength was attained using locally available fine aggregate. Fly ash seemed to be more effective than the natural pozzolan in producing higher compressive and tensile strengths. Incorporation of silica fume had positive impact on strength development of the studied UHPCs. However, silica fume increased the drying shrinkage of concrete.

“…From the definition of RPC, a fine aggregate for concrete is taken in two or three fractions [9][10][11]14]. For example, a coarse fraction of an average of 0.3 mm in an amount of 80% and a small fraction of 0.12 mm -20%, which provides a significant reduction in its intergranular voids.…”

This paper study the process of multilevel optimization of particulate structure of concrete. The improvement of performance characteristics of concrete can be achieved with a minimum binder content. Theoretical and experimental principles for the design of an optimal structure of concrete with an increased concentration of solid phase and operational characteristics, with a complex organo-mineral additive are developed on the basis of a rational proportion of chemical and finely dispersed mineral components. The high density of the structure is achieved by obtaining the dense packages by applying strong particles and grains with high elastic modulus and optimal parameters (dispersion and content) for each structural level. It is shown that it is expedient to use several structural levels of the particles of the clinker phase, and pozzolanization of the matrix must be carried out in accordance with the optimal formulation. Finely-dispersed slag, microsilica and highly dispersed fraction of cement were considered as mineral components, and superplasticizer of polycarboxylate type was used as a chemical additive.
