Analysis of metakaolin as partial substitution of ordinary portland cement in reactive powder concrete
Abellán-García, Joaquín; Torres, Nancy; Santofimio V, Maria (ASTM International, 2020)Over the last 20 years, remarkable advances have taken place in the research on reactive powder concrete (RPC). However, because of the high contents of cement and silica fume (SF) usually used in those types of concrete, ... -
Effect of FC3R on the properties of ultra-high-performance concrete with recycled glass
Abellán-García, Joaquín; Núñez López, Andrés Mauricio; Torres Castellanos, Nancy; Fernández Gómez, Jaime (Universidad Nacional de ColombiaColombia, 2019)Ultra-high-performance concrete (UHPC) is the essential innovation in concrete research of the recent decades. However, because of the high contents of cement and silica fume used, the cost and environmental impact of UHPC ... -
Factorial design of reactive concrete powder containing electric arc slag furnace and recycled glass powder
Abellán-García, Joaquín; Núñez López, Andrés Mauricio; Torres Castellanos, Nancy; Fernández Gómez, Jaime (Universidad Nacional de ColombiaColombia, 2020)The main objective of this research is to develop an optimized mixture of reactive powder concrete (RPC) containing supplementary cementitious materials (SCM), such as Electric Arc Slag Furnace (EASF), and Recycled Glass ... -
Properties prediction of environmentally friendly ultra-highperformance concrete using artificial neural networks
Abellán-García, Joaquín; Torres Castellanos, Nancy; Fernández Gómez, Jaime (Taylor and Francis, 2020)Ultra-high-performance concrete (UHPC) results from the mixture of several constituents, leading to a highly complex material in both, fresh and hardened state. The higher number of constituents, together with a higher ... -
Statistical Optimization of Ultra-High-Performance Glass Concrete
Abellán-García, Joaquín; Fernández, Jaime; Torres Castellanos, Nancy; Núñez López, Andrés Mauricio (American Concrete InstituteUnited States, 2020)This paper presents the experimental results of research carried out involving the compressive strength and slump flow of ultra-highperformance concrete (UHPC) made with cementitious blends of recycled glass flour, recycled ...
