Cement production is one of the most important industries on planet, and humans have relied use dating back to dawn civilization. manufacturing has increased at an exponential rate, reaching 3 billion metric tons in 2015, representing a 6.3% annual growth rate accounting for around 5–8% global carbon dioxide (CO2) emissions. Geopolymer materials, which are inorganic polymers made from wide rang...

Abstract This paper investigates the effect of silica fume on mechanical properties metakaolin-based geopolymers with different silicon-to-aluminum molar (S/A) ratios. Geopolymer has been extensively studied as an alternative to traditional cementitious material because its low CO 2 emissions. Previous studies revealed that application can improve compressive strength geopolymer, however, optim...

In this research, a study is made on the Pervious Geopolymer Concrete (PGC), which based local material (Metakaolin). The inclusion of Ordinary Portland Cement (OPC) as partial substitute for Metakaolin (MK) production (PGCs) has also been investigated. concrete was outputted from (MK), and ordinary cement by weight MK silicate sodium (Na2SiO3) hydroxide (NaOH) solution. All PGC samples were cu...

The properties and performance of geopolymer concrete have been evaluated in numerous studies recent decades. One the fields study is evaluation durability aggressive environments. In this study, influence four experimental factors, including curing temperature (T), weight ratio sand to metakaolin (S/M), environment type (AE), exposure time (Et) were investigated on mechanical metakaolin-based ...
