Thermal deformation and stress of alkali-activated slag concrete under semi-adiabatic condition: Experiments and simulations
نویسندگان
چکیده
This study investigates the deformation of free and stress restrained alkali-activated slag concrete (AASC), respectively, under semi-adiabatic condition. The shows first thermal expansion, which is compensated soon by autogenous shrinkage. subsequent cooling down aggravates shrinkage development tensile stress, eventually results in early cracking concrete. show that condition severer for AASC than isothermal view tendency. evolutions coefficient expansion (CTE) elastic modulus are measured elaborated experimental methods. Simulating summing deformations appears feasible. With consideration relaxation, evolution can be predicted pretty well model used this paper. provides insights into tendency practical circumstances.

SELF-Cured Alkali Activated Slag Concrete Mixes- An Experimental Study
Alkali Activated Slag Concrete (AASC) mixes are manufactured by activating ground granulated blast furnace slag (GGBFS) using sodium hydroxide and sodium silicate solutions. The aim of the present experimental research was to investigate the effect of increasing the dosages of sodium oxide (Na2O, in the range of 4 to 8%) and the activator modulus (Ms) (i.e. the SiO2/Na2O ratio, in the range of ...
متن کاملMechanical Properties and Eco-Efficiency of Steel Fiber Reinforced Alkali-Activated Slag Concrete
Conventional concrete production that uses ordinary Portland cement (OPC) as a binder seems unsustainable due to its high energy consumption, natural resource exhaustion and huge carbon dioxide (CO₂) emissions. To transform the conventional process of concrete production to a more sustainable process, the replacement of high energy-consumptive PC with new binders such as fly ash and alkali-acti...
متن کاملA Study of the Influence of Slag Alkali Level on the Alkali-Silica Reactivity of Slag Concrete
Ground granulated blast furnace slag (ggbs), can reduce the alkali load in concrete, despite its relatively high alkali content. Most research has been devoted to the efficacy of slag with an alkali content of less than 1.0% and this is reflected in guidance documents. A comparative assessment was made of the effect, if any, of the alkali level of ggbs on potential alkali-silica reactivity. Exp...
متن کاملALKALI Activated FLY-ASH Based Geopolymer Concrete
Considering the increasing demand for developing alternative construction materials, due to the growing environmental concerns, this paper discusses the feasibility of alkali activated geo-polymer concrete, as a future construction material. The main objective of this study involves observation of structural behaviours of the fresh fly ash-based geo-polymer concrete, understanding the basic mix...
