mechanical and durability properties of slag based recycled aggregate concrete
in this paper, the possibility of using recycled aggregate (ra) and ground granulated blast furnace slag (ggbfs) to produce a structural concrete was studied by compromising strength to a lesser extent. hence an attempt has been made to study the strength and durability characteristics of the ggbfs-based recycled aggregate concrete. four different groups of mixes were designed by replacing natu...
متن کاملReactivity in Recycled Concrete Aggregate
Full scale tests with crushed concrete used in sub-bases in roads show that the material has capacity to reharden, very slowly but also after prolonged periods of time. The rehardening process in crushed concrete aggregate has been analysed with a thermogravimetric method, comparing the change in chemical composition in the aggregate when set with water, compacted and hardened. It has been show...
متن کاملAssessing relationships among properties of demolished concrete, recycled aggregate and recycled aggregate concrete using regression analysis.
Recycled demolished concrete (DC) as recycled aggregate (RA) and recycled aggregate concrete (RAC) is generally suitable for most construction applications. Low-grade applications, including sub-base and roadwork, have been implemented in many countries; however, higher-grade activities are rarely considered. This paper examines relationships among DC characteristics, properties of their RA and...
متن کاملEffects of Adding Fibre on Strength and Permeability of Recycled Aggregate Concrete Containing Treated Coarse RCA
Abstract—This paper presents the experiment results of investigating the effects of adding various types and proportions of fibre on mechanical strength and permeability characteristics of recycled aggregate concrete (RAC), which was produced with treated coarse recycled concrete aggregate (RCA). Two types of synthetic fibres (i.e., barchip and polypropylene fibre) with various volume fractions...
متن کاملFactors Influencing Compressive Strength of Geopolymer Concrete
To study effects of several factors on the properties of fly ash based geopolymer concrete on the compressive strength and also the cost comparison with the normal concrete. The test variables were molarities of sodium hydroxide(NaOH) 8M,14M and 16M, ratio of NaOH to sodium silicate (Na2SiO3) 1, 1.5, 2 and 2.5, alkaline liquid to fly ash ratio 0.35 and 0.40 and replacement of water in Na2SiO3 s...
