Environmental Impact Analysis of Alkali-Activated Concrete with Fiber Reinforcement
نویسندگان
چکیده
The scientific community is shifting its focus towards construction materials with a low carbon footprint, such as alkali-activated concrete (AAC). present study conducts an environmental impact assessment using the cradle-to-grave approach to examine implications of three different types ambient-cured AACs varied combinations precursors. 28-day compressive strength values mixes used for comparing impacts vary from 35 55 MPa. Among these mixtures, one least chosen further inclusion fibers. Three fiber reinforced AAC containing 0.3% steel, glass, and polypropylene fibers, respectively by volume AAC, are in this study. findings show that Portland Cement has 86% 34% higher than on ecosystem human health, respectively. In production sodium silicate found have highest environment, range 30–50% total impact. various fibers used, glass impact, which 12% 13% plain mix,

ALKALI 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...
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 کاملSELF-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 کاملReinforcement of Glass Ionomer Cement: Incorporating with Silk Fiber
The aim of this study was to synthesis of glass ionomer-silk fiber composite and to evaluate the effect of adding natural degummed silk fiber on the mechanical properties of glass ionomer cement (GIC). For this purpose, natural degummed silk fibers with 1 mm in length and 13-16 µm in diameter were added to the ceramic component of a commercial glass ionomer cement in 1, 3 and 5 wt. %. Compressi...
