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 کاملBasic Mechanical Properties of Basalt Fiber Reinforced Recycled Aggregate Concrete
In order to study the basic mechanical properties of basalt fiber reinforced recycled aggregate concrete, the concrete mix ratio, the length and the volume mixing ratio of chopped basalt fiber yarn are designed for changing factors. A total of 324 specimens have been completed for this investigation. The compressive strength, splitting tensile strength, elastic modulus and axial compressive str...
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 کاملEnhanced Performance of Recycled Aggregate Concrete with Atomic Polymer Technology
The atomic polymer technology in form of mesoporous inorganic polymer (MIP) can effectively improve material durability and performance of concrete by dramatically increase inter/intragranular bond strength of concrete at nano-scale. The strategy of MIP is fundamentally different from most additives currently on the market for industrial applications. When MIP is added to a concrete or masonry ...
