Creep of Slag Blended Cement Concrete with and Without Activator

چکیده

Abstract Partly replacing Portland cement (PC) with lower carbon footprint cementitious materials such as ground granulated blast furnace slag (slag) is considered a practical method for reducing CO 2 emissions in the concrete industry. To mitigate slow reactivity of system and enhance early-age strength, addition chemical activator solution. However, effect on creep behaviour slag-blended concretes remains unclear. This work presents sodium sulfate (Na SO 4 ) compressive PC blended 50 70 wt% slag. Four mixes (with without 2.5% Na activator) containing 395 kg material were prepared. The strain measurements conducted 150 × 300 mm cylindrical specimens 140 days under sustained load. results showed that 70% had than 50% concrete. presence helped reduce but slightly increased In addition, applicability predictive model AS3600:2018 high content was assessed.

Effect of Use of Granulated Slag Instead of Portland Cement on the Properties of Concrete

In this research, 210 concrete cube specimens (15cm) were made replacing 0, 5, 10, 15, 20, 25, 30, 35, 40, 50, and 60 percent of slag powder from Isfahan Steel Mill for cement. The control specimens were made with 350 kg/m3 cement content and the water cement ratio in all specimens was 0.51. The Slump value and compressive strength of concrete specimens in 7, 28 and 90 days were obtained and th...

Experimental Research on the Effect of Ground Slag on Basic Tensile Creep of Early-age Concrete

Tensile creep of concrete at early ages is one of the important factors that affect the stress of restrained and partly restrained concrete. But only few data are available on tensile creep of concrete. The effect of ground slag on tensile creep was studied using lever-type tensile creep tester. Early age tensile basic creep of concrete loaded at the age of 3 days was researched. Results show t...
