superior performances of self-compacting concrete (scc) in fresh state to achieve a more uniform distribution encourage the addition of fibers in concrete which is a motivation for structural application of fiberreinforced concrete. fiber addition reduces the workability of self-compacting fiber reinforced concrete (scfrc). to provide required workability of the scfrc, more paste is needed in t...

Tire derived aggregate (TDA) has been proposed as a possible lightweight replacement for mineral aggregate in concrete. The role played by the amount of TDA replacing coarse aggregate as well as different treatment and additives in concrete on its properties is examined. Conventional concrete (without TDA) and concrete containing TDA are compared by examining their compressive strength based on...

Four different composite mixtures with varying amounts of expanded vermiculite were exposed to high temperatures of 300, 600, 900 and 1100uC for 6 h. Physical and mechanical properties including unit weight, porosity, water absorption, residual compressive strength, residual splitting tensile strength and also ultrasonic pulse velocity were determined after air cooling. Microstructures were inv...

This experiment aims to examine the strength characteristics of structural light weight concrete generated by substituting aggregates like Cinder (class-F) and ECA for coarse aggregate in M30 grade concrete. Lightweight is created from cinder ECA, with cement substituted at 40%, 50%, 60%, 100%. The mix design project 1:1.24:0.63. Using aforementioned percentage, we cast 15 brick specimens measu...

Abstract This work intends to make structural lightweight aggregate concrete by using artificial expanded clay with different replacement levels from normal coarse and improve it a high-performance superplasticizer increase its strength. The mechanical characteristics covered in the present were compressive strength, flexural splitting tensile strength addition freezing thawing resistance. Diff...
