“…Concrete has been widely used in the field of civil engineering. e addition of aggregate to concrete has been found to improve the shear strength, compressive strength, and tensile strength, and the results show that reasonable aggregate and mixing ratio can effectively improve the mechanical properties of concrete members [14][15][16]. Based on these experimental results, by adding aggregate to resin grout to improve the anchoring force, as illustrated in Figure 2, the influence of external uncertain factors can be effectively avoided.…”

With the advantages of large anchoring force and fast anchoring speed, resin cartridge has become the main anchoring means of geotechnical engineering and underground space engineering support. Based on the theoretical analysis, it is clear that adding aggregate can improve the mechanical properties of grout and the bolt-grout interface stress state; the mechanical properties of aggregate are positively correlated with its improvement effect on anchorage performance. By using the numerical simulation method, it is concluded that the addition of steel segments into the resin grout can improve the stiffness of the anchorage system and enhance the energy absorption and antifailure ability of the anchorage system. Relying on the self-developed anchorage mixing device, the effects of steel segment diameter and addition amount on the anchoring force were studied experimentally, and the optimal addition amount of different types of steel segment to improve the maximum anchoring force was determined.

“…Furthermore, the combined replacement of SF and RA exhibited improved mechanical and hydraulic performance [17] as compared to individual replacements of SF and RA, which exhibited inferior mechanical performance coupled with adequate hydraulic performance [18,35]. Thus, it is possible to obtain improved performance from the combined replacement of materials that produced inferior performance individually [30,53,[67][68][69][70][71][72][73].…”

In recent years, pervious concrete (PC) has gained much attention as one of the strategies for low-impact development (LID) in pavements due to its structural, economic, and road-user benefits. This study sought to review and evaluate changes in the mechanical, hydraulic, and durability performance of PC produced with cement and aggregate replacements. A meta-analysis was conducted to elucidate the feasible range of the replacement percentage and the number of materials that could be used to replace cement and aggregates; single or binary replacements were considered. Results indicated that cement-replacing materials, industrial wastes (IWA), and recycled aggregates (RA) met the minimum requirement for the mechanical, hydraulic, and durability properties of PC. The use of a single cement replacement material provided PC with better performance than when cement was replaced with two or more materials or when cement alone was used. Industrial waste was found to be a better replacement to aggregates than RA. The combined replacement of cement and aggregates with IWA and other cement-replacing materials was the most effective method for improving the mechanical, hydraulic, and durability performance of PC. Replacements of up to 40% was considered viable for cement replacement, while up to 50% replacement was considered practical for aggregate and combined replacement. PC incorporating different cement-replacing materials exhibited equivalent or improved mechanical properties and maintained hydraulic performance compared to cement-based PC. Nonetheless, limited studies are available on the durability performance of PC made with cement and/or replacements. Thus, the durability of PC coupled with the applicability of replacement materials acquired from different locations need to be evaluated to address the viability of producing more durable PC with the use of replacements.

“…Se debe tomar en cuenta la proporción de CCA y otras adiciones para que no afecte el rango de resistencia prevista en su diseño; pues se supone experimentalmente que 15% reduce gradualmente la fuerza compresiva, y que por tanto se recomienda no superar el 10 a 12%; al igual que la tracción en su relación a/c que mientras esta sea mayor, la porosidad también ascenderá, en este caso el porcentaje más adecuado es hasta un 10% (Ayesha, et al, 2018); con lo que respecta a los costos del cemento se reduce en un 31,5% de sustitución parcial (Hu, et al, 2020). Por otro lado cuando se busca diseñar un tipo de concreto permeable para pavimentos es recomendable el HS que logra alcanzar 52,4 MPa con un 9% de masa reemplazante en resistencia pero para una permeabilidad optima se recomienda 6% que resulta un 208% más permeable y 16% menos resistente (Huang, et al, 2020)…”

El presente artículo recopila e identifica la adición de ciertos aditivos minerales de uso más frecuente en la industria de la construcción como modificadores del concreto durante su estado fresco y endurecido, los cuales en su mayoría son usados como remplazo parcial del cemento. Actualmente los investigadores buscan optimizar las propiedades del diseño de mezclas dependiendo al uso por el cual son concebidas, así mismo que sea factible económicamente y respetuoso con el medio ambiente. Se revisaron 50 artículos indexados entre los años 2010 y 2021 distribuidos en las siguientes bases de datos: 37 artículos de Scopus, 10 artículos de ScienceDirect, 2 artículos de Springer y 1 artículo de SciELO. Los aditivos en estudio son escoria de alto horno granulada (EAHG), cenizas volantes (CV), humo de sílice (HS), ceniza de cascarilla de arroz (CCA). En su mayoría presentan una mejora considerable en sus características mecánicas de tracción, resistencia a la compresión y módulo de elasticidad. La adición de CV mejora en la mezcla del diseño durante su estado fresco, la CCA durante su estado endurecido y las mejores resistencias para el HS; sin embargo, la EAHG resulta cumplir con casi todas las expectativas en mayor porcentaje y así mismo junto con la CCA, son potencialmente competitivos.
