Impacts of climate change on optimal mixture design of blended concrete considering carbonation and chloride

Xiao-Yong WANG

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 2,   Pages 473-486 doi: 10.1007/s11709-020-0608-5

Abstract: Many studies on the mixture design of fly ash and slag ternary blended concrete have been conducted.This study presents a procedure for the optimal mixture design of ternary blended concrete consideringThird, illustrative examples are shown for mixture design of ternary blended concrete.The analysis results show that for ternary blended concrete exposed to an atmospheric environment, arich mix is necessary to meet the challenge of climate change, and for ternary blended concrete exposed

Experimental investigation on mechanical properties of binary and ternary blended pervious concrete

Rekha SINGH, Sanjay GOEL

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 1,   Pages 229-240 doi: 10.1007/s11709-019-0597-4

Abstract: The purpose of the investigation was to study the effect of binary and ternary blends of cement on the mechanical properties of pervious concrete (PC) specimen through destructive (DT) and non-destructive testing (NDT). Various combinations of fly ash (FA), limestone powder (LP), metakaolin (MK), and silica fume (SF) as mineral admixtures have been investigated to partially replace the cement up to 30% by weight in PC. Standard cube specimens of size 150 mm × 150 mm × 150 mm of binary and ternary blends of mineral admixture of pervious concrete were prepared to conduct standard compressive strength test and split tensile test at 7 and 28 days of curing. The ultrasonic pulse velocity (UPV) test and Rebound Hammer test were used as a non-destructive testing tool to substantiate the robustness of PC and to determine the approximate mechanical properties where other destructive testing tools are not feasible in case of in-place pervious pavements. Overall the pervious concrete made with LP based ternary blends (PLM and PLS) were found to perform better than FA based ternary blends (PFM and PFS) and control mix (PC) in destructive and non-destructive testing.
